Got a MAK 90 that sheared its rear trunnion pins and need to get it fixed. Anyone near Olympia or Lakewood have AK jigs and a shop press? Also, does anyone have advice to offer for dimpling the thick Chinese receiver? Do I also dimple the trunnion or can it just be chamfered with a drill? Sent from my STV100-1 using Tapatalk

Please forgive my ignorance on this platform, and my jumping off topic, but is this area a common failure point? Is it basically a rivet?
Thanks, curiosity was bugging me.

Sent from my Nexus 10 using Tapatalk It's not basically a rivet...it IS a rivet. Two in fact. I wouldn't say it's "common" but it does happen on high mileage AK's or ones that have had the wrong rivets installed and incorrectly pressed. I have owned and built more than a few AK's and I have never had it happen to me. The reason is because all the mass of the bolt and carrier slams into that rear trunnion/stock tang every time it's fired. After repeated use they can fail. A lot of guys will put a recoil buffer in there which is actually doing more harm than good. Leave the recoil buffers out and periodically check the stock for front to rear movement. Adding to that, I recommend removing the stock and checking the trunnion itself for the movement because sometimes the stocks fit so tight into the receivers that they won't wiggle if installed.
