Tallpine,
Ok, I think the breech and thus lock are a bit too far forward, giving the tang area a flat area, sorta hump back. It usually happens with precarves if you don't take the barrel channel back more, but sometimes you cant, especially if the lock is already inlet, thus my question...
I agree with Mike's other observations and would suggest also a different tang, not necessarily a long lollipop, but a pointed tang with a screw or even two in it would be more SMR like than the older flared tang.
No offense intended and I'd be proud to carry it as is, just making my observations.
