cool so it is do-able, just not guaranteed by CSA
I never planned on a 7.62 build, but the barrel showed up and it was hard to resist. I will be putting the upper together next weekend, but I did hand tight assemble the barrel to the upper receiver and ran the bolt to feed 7.62 through .223 lar mags and it seemed to work fine with 3 rounds, but would jam if I put in 5
mind you, I wont be running corrosive through it, and price of non corrosive is more than .223 costs
bolt is DPMS, bought from fabsports, they only had 1, and that was 2 months ago. Probably not as good as the other brands, but 1 bolt is better than 0 bolts
