Well a lot of this info has been very helpful, thanks. However Id still like further elaboration on what needs to be done inside the rifles action parts wise, and where I can find a direct source for parts or a complete accurized rifle.
I already know how to do most of this stuff to a bolt action, however the workings of a semiauto are a little more complex, and still a bit of a mystery to me. so if anyone can shed some light on what I need to do to the inner workings, it would be helpful.
As for the claims of sub MOA out of the box rifles, I really dont know what to say, other than I have never heard of a 1/2 MOA semiauto rifle yet in existence. most that are affordable are around 1 MOA give or take, and tend to hit where you aimed at 100 yards and do it repetedly. If it was so easy to get a semi auto to shoot a reliable 1/2 MOA there would be no bolt action sniper rifles in police or military service anymore.
Furthermore only 11% of snipers actually can take full advantage of a 1/2 MOA rifle, its basically more accurate than it needs to be, or than can be exploited by most skilled marksmen. The competition world record 5 shot group is 4.5 inches -just under 1/2 MOA- center mass at 1000 yards with a bolt action Mcmillan.50 cal, and it was fully sandbagged into place, the shooter needed only pull the trigger. furthermore the current U.S army Designated marksman rifle, the M-14 based 'M-39 EMR' shoots just under 1-MOA and its fully tooled up. so theres no way an out of the box Norinco is going to pull sub MOA groups without some work. basically 1/2 MOA rifles are just a means of improving the odds of a cold boar shot hitting somewhere where you want it to at extreme ranges, up to, or significantly greater than 1000 yards.
Just the facts jack, thats all I need.
