What to do with parts in the junk drawer.

[Skip]

I'll use a "Sig Brace on it just to be safe........

You might want to write the ATF and make sure how you use the Sig Brace doesn't change the definition of the locker.

[ZERO THEORY]

Good idea, I need to do something with the close to 30 I have laying around

I'll take a couple off of your hands. I, for one, actually like A2 grips.

Spare parts?? I thought if you had as much as an extra roll pin, you were suppose to start a build?
