Nice rifle. My first build was a 5.56 infantry rifle (20" barrel). My second is a 6.8. Each time I get better at picking the right components. I spent a fair amount of money on economy parts I later replaced with premium parts. I would have been slightly better off if I slowed down and purchased the best barrel, best HG, best trigger, etc. in the first place. Oh well, so it goes. In the end, I have a nice lower and two nice uppers. Plus I'm tempted to build another 6.8 upper with even better parts. Its an expensive hobby. - CW
