WTT Remington optics mount for collapsable AR stock
Al's Custom Optic Mount for Remington vent rib shotguns. It's the "no gunsmithing" model and is .306". I used this on my Remington Competition Master.
It's basically a Picatiny rail that clamps on the barrel rib. Very solid.
It's $60 new + ship.
WTT for a 6 position AR collapsable stock with receiver extention and buffer/spring. Prefer RRA, but will consider others.
If you want to buy it, I'll sell it for $45 shipped to you in the CONT US.
Thx for looking.
