I have a pencil problem.  AR6720, R6001, now this.

Procured this upper Friday at AIM’s garage sale.  Yeah, it has a 1/2 moon bolt but everything else is normal.  Hand cut M4 ramps w/o finish, “4” stamp at the front (is this a leftover XM4 receiver?) and an A2 (800) elevation wheel with no Z.  Accurate Forge marked, skinny six hole H/Gs; I’m guessing 1992-Y2K ish.  No barrel date, just “O”

Any other ideas?
