Top one isn’t quite finished just waiting on A2 buffer & spring and changing handle. Threw the RTS style sights and my vmx3t on there for now so it wouldn’t be naked. All 3 rifles are sporting the Rainier mini comp and started out as 80’s. Played musical rails with the two 16" rifles. The top is a adams arms mid length piston build. It was built from parts I accumulated over the course of last year. The bottom was a bcm complete upper I swapped out the rail to a pri gen 3 and fsp to a lo pro bcm gas block. Took the old rail off the bcm and used it on my adams build. The middle was my first 80 and was a bcm 20" complete upper.
Stupid light and pretty effective for what it is. Only bad thing is I had to do a field repair and slipped my cresent wrench on it puting a nice rounded mar on 2 sides of it lol. Not like it matters tho as I could care less about looks.
