Hey, has anyone ever fired milsurp 5.56mm NATO out of a Mini-14, or other .223 civilian rifle? Does it give decent accuracy, or could one expect to be dissappointed? The reason I ask, is that I know the M-16A2's that the Military has used for the last few years had a different barrel twist than the M-16A1 and earlier weapons, due to the adoption of a(n) Belgian-designed projectile. ( I was going to buy some at my local gun store, but all available supplies of 5.56mm surplus have dried up, for the time being.) However, I've got a friend who has some he gave me, just wondering...
