Hi all,
Just a quick question: what rail is the gentleman in this video using on his carbine? Thanks.

looks like a monolithic set up to me. not sure though, I’m curious as well
It’s an Aero Precision Monolithic C.O.P. Upper Reciever, available here.
That upper looks just like the Armalite SPR upper. What’s the difference?
Same thing, made for Armalite by Aero Precision.
