Early American attempts to produce an AK were absolute crap - why? Might have had something to do with the American fascination with "straight and tight". A couple of the makers thought that they should use the best quality parts they could find - including rivets. In went the steel rivets, to hold the front trunion exactly square to the receiver. After the gun destroyed itself, they tried hardened steel rivets. Same result. The answer? Leaded rivets, like the ones the Russians and Chinese use. It doesn't help accuracy to have the front trunion wandering around on flexi-rivets, but then, it isn't meant to. If you take Rifle Dynamics AK builder course, you'll find that there is a different design and build philosophy at work, this philosophy extends to the T81 since the folks who designed the T81 were educated by folks who grew up in the culture that produced the AK. Incidentally, there are folks who can shoot these rifles very well indeed, just not off a bench and not at one inch targets, because it isn't a bench gun and it isn't a target gun. It is better than a 5 inch gun, more like a 3 inch gun (if you can shoot 3 inches with irons standing unsupported) - 3 moa is 9 inches at 300, put a pie plate on your chest and ask if that's fit for purpose. If the gun is bent at rest when cool, what does that mean when the gun is hot and being fired, and the trunion and barrel both move? I don't know, and neither do you
