I have never done a 7.62, I have done a S-12 and am in the middle of my .308. I am just waiting for my FCG. I used the Tromix moded FCG in my S-12 and I am waiting for my Dinzag modded FCG for my .308 If you use a regular G2 you will have to grind at some point
The .308 does not need a bullet guide instaled. Aftermarket mags such as surefires are all US parts. The FBMG's current gen only count as one part as the followers and floorplates are imported.
I hope i have helped some
just curious, why do a conversion?
do you guys have pics?
