PM 4 : Introduction Introduction Term: Brown-bag special Definition: The completely and totally disassembled gun in a bag that a customer or buddy brings to you to put back together because said customer or buddy just “couldn’t stop there.” Usually the brown-bag special is missing one or more key components, and often has unrelated parts in it that were found on the floor adjacent to parts originating from the disassembled firearm. The brown bag special is one of the reasons for this book’s existence. Gunsmiths around the country buy these books for a reason, sometimes just to add to the library (you can never have too many resources in your gun library). Of course, you don’t have to be a gunsmith to make use of this book and it is quite handy for the average dude who simply wants to detail clean or just to learn more about how his firearm works. Okay, straight to business, now. As useful as a book like this is, it is simply impossible to present perfect images of every step, from the best angle, through invisible fingers, palms, and receiver walls. There may come times where it is necessary for the user to read between the lines, or create simple mental images of the description. For example, we may instruct you to remove the four action screws from a rifle, but the picture shows and indicates only one or two, since the other two or three happen to be in similarly obvious locations on the gun. Or a decent image is simply impossible to capture so we point out what needs to be done and the effect that it will have. For example: “This receiver is narrow enough to preclude a good internal image. Drive out this pin and this will happen. Drive out that pin and that will happen. Catch the twelve and a half springs that drop free when you do.” You will find that parts schematics will be of immense help in these instances. The truth is that most gunsmithing or takedown tasks can be accomplished with a handful of useful tools. Many guns require special tools to do this and that, and such will be noted in the text, when applicable. Otherwise, the items detailed in the Tools section in the beginning of this book should suffice for any of the rifles detailed in this guide. There are four tools that are the most useful and I would like to touch on those here. The first and most useful is a functioning brain. “Guns are always loaded” is the maxim and I can confirm that removing any distractions, particularly when unloading or checking the load status, can be critical. Otherwise the operation can result in holes in things that shouldn’t have them. A gun’s primary safety is your well-functioning head, because if that isn’t working, you shouldn’t be anywhere near a firearm. Or me. Triple-check that the firearm is unloaded, especially for firearms with detachable magazines. Too often, people remove a loaded magazine and forget that there is still a live cartridge in the chamber. Stick your finger in the chamber, in addition to a visual check. If the bolt slams shut on your digit, you’ve a pretty good indication that the check was successful. It’s really a treat when it happens with a bolt or other manual action. Please don’t ask me how I know this. The second tool is the digital camera. Its value cannot be overstated. Taking what are essentially free pictures whenever you feel the need will make disassembly and reassembly much more practical. This is not to mention the proof you will have when you tell the customer that you found a bunch of grass, or a key (yes, that really has happened) in his receiver and he meets that statement with profound skepticism. It isn’t unusual when compiling these books to discard half again as many pictures that were, in the end, used. The third tool is the internet. In the 21st century we have access to a tremendous amount of information, because it seems that everybody wants everybody else to know what they are doing and how they are doing it. You will find everything from idiocy to priceless wisdom, so you will have to filter it out. But when you find that schematic you couldn’t find elsewhere you will be thankful indeed for the information superhighway. S5432_pgs001-006.FrtMttr.indd 4 3/1/16 2:23 PM Introduction : 5 The fourth tool is the third hand. Every gunsmith needs one, but alas, not a single one possesses it. So we make do with a heavy, sturdy bench vise with padded jaws. A few more suggestions. Don’t work on guns in thick carpet or outside, since you will drop parts. Always wear safety glasses, since your eyes are way, way more important than your comfort. Read the firearms’ user manuals. I know this is a tall order for the American male (any American honestly), but please do it. Finally, brute force is the enemy. If it doesn’t come out with a light tap, there is probably a good reason. Like a set screw. Or you are trying to tap it out the wrong way. “Hit it harder” and “get a bigger hammer” generally aren’t mantras to live by when working on a firearm. Check out the index in the back if you don’t see the gun you are looking for. Some models are similar or identical to others, and generally the steps to take down the basic model of rifle are going to be the same for the more enhanced target/tactical/deluxe versions of the same gun. It’s also interesting to note that, of late, many replicas of popular centerfire rifles such as the M4 or Uzi have emerged, and several such examples are included in this revision. Furthermore, as traditional rifle sales have given way to “black” rifle and concealed carry pistol sales, manufacturers have had to reimagine how to make a quality and effective rifle at a cheaper cost, i.e. below $400. The result is the use of some interesting technologies and design trends that result in such guns as the Ruger American and Savage B.Mag. Limited space requires new additions to displace older models, so please don’t be offended if the takedown you are looking for is not found here. There are a number of older editions available online and you can also contact the publisher for pdf copies of older chapters. Lastly, space also precludes the inclusion of the oh-so-useful schematics. Many or all of these can be found in the huge Gun Digest Book of Exploded Gun Drawings. Kevin Muramatsu Sleep deprived, yet caffeine supplied White Bear Township, Minnesota October 2015 S5432_pgs001-006.FrtMttr.indd 5 3/1/16 2:23 PM 6 : Dedication Dedication As I finished up this revised edition on October 25th (yes, the manuscript deadline date), I took a break and looked up events that happened on this day in history. One remarkable occasion stood out. On the morning of October 25th, 1944, occurred what is known as the Battle at Samar. This was an adjunct engagement of the rather larger Battle of Leyte Gulf when (the insufferable buffoon) General MacArthur “returned” to the Philippines. Without going into too much detail, because I’d like the readers to look it up, this engagement was one of the most lopsided in naval history yet had a surprisingly lopsided result in turn. For those with short attention spans, Wikipedia has a surprisingly concise account. There are better resources written by many that were present, and these accounts tell the whole story. Anyway, in a nutshell, a powerful fleet of IJN surface warfare ships, four battleships, eight cruisers, and eleven destroyers got into shooting range of a much smaller USN task force composed of six escort carriers, three destroyers and four destroyer escorts. Needless to say, the USN was in as poor a set up as can be imagined, yet the destroyers and escorts plunged head first into a surface engagement that was tactically hopeless, in order to buy time for the six small carriers to escape. In theory, the IJN had all the advantages, yet they lost the battle, being turned away in frustration (their target was the invasion force at Leyte), largely due to the boldness of the attacking escorts and aircraft from the carriers and the mass confusion that erupted in what amounted to a massive melee at short ranges. In the end, we lost “only” two escort carriers, two destroyers, and one destroyer escort. Of particular interest to me was the account of the destroyer USS Johnston and its CO, and of the destroyer escort Samuel B. Roberts. The Johnston was eventually lost after suffering tremendous damage and casualties, with Commander Evans receiving the Medal of Honor, posthumously. The Roberts was also lost after inflicting far disproportionate amounts of damage to the Japanese. Here’s the point. A lot more Americans would have died had not the escorts of Taff y 3 boldly charged into the far larger and more numerous guns of the Japanese battleships. These actions and others similarly performed yet uncounted ensure the freedom we all take for granted. The actions continue to be performed today. I’ll give you one guess to whom this revised edition is dedicated. Acknowledgements As with the last of these books that I revised, I pretty much did and obtained everything myself. So I guess I’m left with thanking Gun Digest for the job of making these revisions and putting my name and mug on the covers. I suppose I should thank the several gun distributors for making sure they had what I needed in stock. Now if only they could produce a PMR-30. Oh, and thanks, Corrina, for not firing me. A Note on Reassembly Most of the rifles covered in this book can be reassembled by simply reversing the order of disassembly, carefully replacing the parts in the same manner they were removed. In a few instances, special instruction are required, and these are listed with each gun under “Reassembly Tips.” In certain cases, reassembly photos are also provided. If there are no special instructions or photos with a particular gun, you may assume that it can just be reassembled in reverse order. During disassembly, note the relationship of all parts and springs, take digital photos of the installed arrangements, and lay them out on the workbench in the order they were removed. By following this procedure, and referring to your own digital images, you should have no difficulty. S5432_pgs001-006.FrtMttr.indd 6 3/1/16 2:23 PM TOOLS Tools : 7 Countless firearms, old and new, bear the marks, burrs and gouges that are the result of using the wrong tools for taking them apart. In the interest of preventing this sort of thing, I am including here a group of tools that are the best types for the disassembly of rifles. Except for the few shop-made tools for special purposes, all of those shown here are available from one of these three sources. Brownells, Inc. 200 South Front Street Montezuma, IA 50171 B-Square Company P.O. Box 11281 Fort Worth, TX 76109 Williams Gun Sight Company 7389 Lapeer Road Davison, MI 48423 General Instructions: Screwdrivers: Always be sure the blade of the screwdriver exactly fits the slot in the screw head, both in thickness and in width. If you don’t have one that fits, grind or file the top until it does. You may ruin a few screwdrivers but better them than the screws on a fine rifle. Slave pins: There are several references in this book to slave pins, and some non-gunsmith readers may not be familiar with the term. A slave pin is simply a short length of rod stock (in some cases, a section of a nail will do) which is used to keep two parts, or a part and a spring, S5432_pgs007-011.Tools.indd 7 together during reassembly. The slave pin must be very slightly smaller in diameter than the hole in the part, so it will push out easily as the original pin is driven in to retain the part. When making the slave pin, its length should be slightly less than the width of the part in which it is being used, and the ends of the pin should be rounded or beveled. Sights: Nearly all dovetail-mounted sights are drifted out toward the right, using a nylon, aluminum, or brass drift punch. 3/1/16 2:25 PM 8 : Tools 1. 2. 3. The tiniest of these fine German instrument screwdrivers from Brownells is too small for most gun work, but you’ll see the rest of them used frequently throughout the book. There are many tight places where these will come in handy. 4. For heavier gripping, these Bernard parallel-jaw pliers from Brownells have smooth-faced jaw-pieces of unhardened steel to prevent marring of parts. 5. For situations where a non-marring rap is needed, this hammer from Brownells is ideal. It is shown with nylon faces on the head, but other faces of plastic and brass are also available. All are easily replaceable. 6. For drifting out pins, these small all-metal hammers from B-Square are the best I’ve seen. Two sizes (weights) are available and they’re well worth the modest cost. When a larger screwdriver is needed, this set from Brownells covers a wide range of blade sizes and also has Phillips- and Allen-type inserts. The tips are held in place by a strong magnet, yet are easily changed. These tips are very hard. With enough force you might manage to break one, but they’ll never bend. You should have at least one good pair of bent sharp-nosed pliers. These, from Brownells, have a box joint and smooth inner faces to help prevent marring. S5432_pgs007-011.Tools.indd 8 3/1/16 2:25 PM Tools : 9 7. For situations where reach and accessibility are beyond the capabilities of sharp-nosed pliers, a pair of large sharp-nosed forceps (tweezers) will be invaluable. 8. One of the most-used tools in my shop is this nylon tipped drift punch, shown with an optional brass tip in place on the handle. It has a steel pin inside the nylon tip for strength. From Brownells, and absolutely essential. 9. A good set of drift punches will prevent a lot of marred pins. These, from Brownells, are made by Mayhew. The tapered punches at the right are for starting pins, the others for pushing them through. Two sizes are available-4 inches or 6 inches. 10. These punches by Mayhew are designed specifically for roll pins and have a projection at the center of the tip to fit the hollow center of a roll pin, driving it out without deformation of the ends. From Brownells. 11. Some of the necessary tools are easily made in the shop. These non-marring drift punches were made from three sizes of welder’s brazing rod. S5432_pgs007-011.Tools.indd 9 3/1/16 2:25 PM 10 : Tools 12. From Brownells, this wrench is specifically designed for use on the barrel nut on the Winchester 150/250 and 190/290 series. 13. The B-Square stock bolt tool automatically centers in the access hole at the rear of the stock, and its wide cross-piece easily “finds” the screw slot. The T-handle gives good leverage. 14. This is the end of the B-Square general stock bolt tool, showing the replaceable cross-piece which contacts the screw slot. S5432_pgs007-011.Tools.indd 10 15. This excellent new hammer from B-Square is the same size and weight as the larger of the two hammers shown elsewhere in the tool section, and has an additional feature-knurled replaceable striking faces, in your choice of brass or steel. 16. When dovetail-mounted sights are not supertight, this “Sight-Pusher” will move them out or into place gently, without the marring which can occur with the hammer-and-drift method. From Williams. 3/1/16 2:25 PM Tools : 11 17. A digital camera, even a cheap, low-resolution model can be invaluable. The ability to take a quick, free photo of anything that you are doing for reference is a modern convenience that one would be foolish to neglect. Inner Magazine Tube Disassembly: With very few exceptions, the disassembly of the inner magazine tube is the same for most rifles having this type of magazine system. The knurled knob at the end of the tube is retained by a cross pin, with one or both ends of the cross pin protruding to lock the tube in the gun. Most of the pins are driven out toward the non-protruding (or smooth) side. The tube should be supported in a V-block or a slightly opened bench vise during this operation, to avoid deformation of the thin walls of the tube. When the pin is out, the knob can be removed from the end of the tube, and this will release the magazine spring and follower. In some cases, the spring will be slightly compressed, so take care that it doesn’t get away, and ease it out. In those cases where the cross pin protrudes on both sides, the pin will be slightly tapered. These should be driven out toward the larger end of the pin. Some box-type magazines can be disassembled, but most of them are of staked construction, and in normal disassembly should not be taken apart. A Note On Coin-Slotted Screws Many action takedown screws and main stock retaining screws have slots designed for use with a coin, the theory being that a shooter in the field might not have a large screwdriver at hand, but would be likely to have pocket change. The slots in these screws are wider than normal, and the floor of the slots will be curved, to match the curve of a coin edge. It is possible, and advisable, for the gunsmith or advanced amateur to alter a large shop screwdriver to exactly fit these screws. In general, though, the following advice applies: Do not use an ordinary, unaltered large screwdriver on coin-slotted screws. S5432_pgs007-011.Tools.indd 11 3/1/16 2:25 PM 12 : Anshutz MSR RX22 Anschutz MSR RX22 Similar/Identical Pattern Guns The same basic assembly/disassembly steps for the MSR RX22 also apply to the following gun: ISSC MK22 Data Origin: Manufacturer: Cartridge: Magazine capacity: Overall length: Barrel length: Weight: 6.9 Anschutz MSR RX22 Germany J.G. Anschutz GmbH, Ulm, Germany .22 Long Rifle 16 rounds 35.8 inches 16.5 inches pounds The Anschutz RX22 is a match grade bulky-looking thing that resembles the FN SCAR rifle. Unlike the SCAR, the RX22 is a rimfire rather than centerfire and is somewhat lighter in weight. Available in several configurations and colors, this rifle is quite accurate with a match grade barrel and adjustable match grade trigger. The ISSC MK22 is virtually identical, with some minor cosmetic changes and with a different trigger group. The takedown steps should apply greatly for that rifle as well, and they should, since both companies collaborated in order to make the rifles. S5432_pgs012-019.Anschutz MSR RX22.indd 12 3/1/16 2:25 PM Anshutz MSR RX22 : 13 Disassembly: 1. Remove the two screws at the forward and rear ends of the fire control housing. The push the remaining pins out to the left. 2. picture A Lift the upper assembly from the fire control assembly. picture B 3. Remove this screw and its opposite on the left side (picture A). Fold the stock and then remove this screw (picture B). Removal of this screw frees the buttstock, the stock unit being pushed from the receiver by the thick recoil reduction spring. 4.

Remove them to separate the left and right halves of the assembly module. Remove the bolt. 33. A small set screw is in this hole. Remove it and push the pin that the screw retains out from the other side through this screw hole. This frees the firing pin to be removed out the rear of the bolt, and the firing pin safety plunger out to the left. 34. The bolt cover on the top of the bolt is held by three Torx screws. Remove this cover. Inside the top of the cover lies the firing pin return spring. 35. Tap out this pin from the bottom up to remove the extractor and spring. Reassembly Tips: 1. When rebuilding the fire control assembly, place the parts in the right side housing wall. Be sure to control the hammer spring. Then reattach the left side wall (which should have the hammer rebound spring mounted in it) to the right side. As the hammer is about to seat, pull the long upward pointing leg of the rebound spring in front of the hammer spud that it sits against. 2. The bolt guide rods are easily reassembled into the bolt assembly by partially inserting the rods from the rear as the springs are inserted from the side and forward. The springs will be compressed, but not by much. S5432_pgs012-019.Anschutz MSR RX22.indd 19 3/1/16 2:26 PM
