I keep seeing these nice smooth and light gas blocks without the picatinny rails. Can you buy a kit like that? I dont see it listed on the AA website.
I am interested in this too. I see them on the ultralite uppers, but not sold separate
I'm also patiently waiting. I already finished my build, just waiting for this light weight piston kit to come out. I heard that the 308 will be coming out also, so I bought a Bushmaster 308 ORC . I guess I'll be waiting for a while till those come out too.
