This is my first carbine build, I shoot the 77 gr and 69 gr bullets more than the 55's. I like the idea of the chrome lined 1-7 twist barrels. My question is; am I going to have problems shooting the heavier bullets with the short gas system? I.E. ripped off case rims as I have seen with some carbines or is that some other problem with the gas system? I am looking at the mid length 1-8 twist RRA barrels also thinking the extra two inch gas system might be the way to go - but then - the chrome lined barrel would out last the SS barrel. Any ideas? Maybe a 14" barrel with a perm installed flash hider? think that would work better? I want at least 1MOA from it , I get that with all my handloads through my 20" barrels w/1-7 twist - free floated
