Reminds me of a kid doodling in school. Heck the bolt, carrier and trigger group are worth what you paid, the rest is just gravy!
I knew I'd regret not getting a couple of these, now I'm starting to feel the pangs!
You'd think that a spent 7.62x39 case would fit the bill for those circles. It'll be interesting to see what Tony can find that would fit. They might have been able to just push & twist, that replacement Alby wood is really soft (well some of mine are anyhow, they will take an indentation from just my fingernail)
