badman400 3 Posted March 25, 2010 Report Share Posted March 25, 2010 What would cause a semi-auto MAK-90 AK-47, milled receiver, to double up or go FA on 2-3 shots? This has only happened twice and after the first time a new trigger was installed, which seemed to cure the problem. This seemed to happen when using a certain magazine, although I dont' see how that could make a difference. I know that everyone is hesitant to talk about full auto in general for obvious reasons, but I am asking so I can find out what to look for and repair to make sure this never happens again. I'm not a novice with firearms, and everything I have is legal, but I just can't figure out why this happened. Any help would be appreciated. Quote Link to post Share on other sites
SirROFL 13 Posted March 25, 2010 Report Share Posted March 25, 2010 I'm no expert, but, it sounds something like a slamfire to me. In case you don't know what that is... http://en.wikipedia.org/wiki/Slamfire Make sure your bolt face is clean especially around the firing pin so it doesn't get stuck, and see if your MAK has a firing pin spring to hold it back during regular cycling. Anyone else got any ideas? Quote Link to post Share on other sites

Moe Zambeak 53 Posted March 25, 2010 Report Share Posted March 25, 2010 Weak/ wrong sized disconnector spring can be a cause too. Quote Link to post Share on other sites

MT Predator 2,294 Posted March 31, 2010 Report Share Posted March 31, 2010 Buddy of mine had a .22LR AK that went FA on him at a public range that has pretty restrictive rules. Lucky for him it was a .22 and nobody noticed. The range is frequented by local LEO as well. Consequently, that rifle was returned to the manufacturer for a replacement. As it was a new rifle, I'm guessing maybe a slam fire because it was gummed up with cosmoline? Quote Link to post Share on other sites
