Im sure this question has been posted to death but how would one fix mag wobble on a wasr 10? I seem to remember hearing something about shims but I dont know were to find them. Any help would be appreciated.
Most just don't fix the wobble, unless it's so bad to impact relibability it's not really a big concern. Using Bulgarian waffle mags will tighten things up, if you add shims it's just tabs of metal welded to the inside of the mag well that stop the mag from wobbling.
The shim method uses computer slot covers.
If you look on the back of a PC you'll see stamped steel covers over the unused slots. One type has a "dimple" that's about the same size as an AK receiver dimple, but not as deep.
Get two covers. (Most computer repair stores will probably give you several).
Saw and file the cover away from around the dimple until you have a dimple with a narrow border around it. This will leave a flat surfaced area around the dimple to help bond it to the receiver.
There are two methods of bonding the dimples into the receiver. One is soft solder, the other is epoxy glue.
For the soft solder method, remove the paint or finish from the inside of the receiver where the dimples will be attached. (Solder will not stick to paint or gun finishes, it has to be removed). Leave the area rough by using sand paper to roughen the metal.
Remove the finish from the bottom flat area of the dimple.
Apply flux to the dimples and apply a thin coat of soft solder to the flat border area. Let cool.
Put the dimples into the receiver one at a time and warm the receiver JUST until the solder melts. DO NOT OVER HEAT. All you need is about 350 to 400 degrees of heat and that isn't that hot.
After soldering, wash out the receiver with hot soapy water to remove the flux fumes to prevent rusting.
To epoxy, roughen the areas in the receiver and the flat border of the dimples with sand paper to improve the bond.
Clean the dimples and the receiver THOROUGHLY with a strong liquid cleaner like Simply Green or Greased Lightning, then clean again with Acetone or lacquer thinner to thoroughly degrease both the dimples and receiver. Dry both.
Use a wax like Johnson's Paste Wax or even shoe polish wax to wax everywhere you DON'T want the epoxy to stick. This prevents stray epoxy from making a hard to clean up mess.
Get a really good measured mix of the epoxy to insure a good bond. You can do it by eye, or by using a powder scale to weigh the two components.
Get a good mix. I'd use 1 hour epoxy and mix at least 2 minutes longer than the label says. Try not to whip the mix and get air bubbles in it.
Apply the epoxy to the under side of the dimple and lightly clamp in place with a "C" clamp.
Put the receiver somewhere warm, like in the sun or inside a car on a hot day. The heat will speed and strengthen the cure. Allow the epoxy to harden to the consistency of firm rubber, then use a plastic or brass "knife" to cut away any excess. (Note that heat will cause the epoxy to set up faster than you think so watch it closely).
Allow to fully harden then clean up the receiver and remove the wax.
An alternate method is to use Loctite Red bonder instead of epoxy OR you can use the new Loctite "Black Max" that Brownell's sell. Black Max is made to bond shotgun sights on and is a Super glue type glue mixed with a rubbery bonder to improve strength.
A buddy of mine had a fair amount of slop in his WASR, which caused some reliability probems with TAPCO mags. The milsurp ones were plenty tight, and the problem went away. i would try other mags if there was some issue. shims are just asking for a headache, unless it's not reliable at all, the shim away.
I have had great success in making mags fit better by bending the front lug out slightly. this works on AK, PSL and AK-74 plastic magazines. you take an adjustable wrench and slip it over the front of the mag to a point just below the lug, then bend foward slightly. AK steel mags need the wrench braced against the floor as they are harder to bend. other mags don't need as much force and plastic mags will crack easily so take your time.
this does work and to date I have fitted magazines to several rifles including a WASR1, WASR2 and my PSL.
No need for repair, you have a rifle that any mag you can get your hands on will fit. And if your like me and too lazy to count your shots give 'er a shake, usually the fewer rounds in the mag the more pronounced the wobble is. I have a wasr gp 10/63 that has zero wobble when mag is full, and beaucoup wobble when empty.
