There used to be a guy on here USAGOLD (I think) that sold Rock River parts for a great price.
I have quite a few extra BCGs sitting in the safe thanks to him.
Not seen him post in awhile unfortunately.

And, they're not even in stock. "TO PURCHASE, SEE YOUR LOCAL FIREARMS RETAILER/FFL HOLDER". And, we all know what that means. Probably no one has it.


I got my RRA stripped lower off the shelf here

parabellum, an A1 upper with a forward assist and a Canada Colt A1 stock, can't get any cooler than that.

I like the POF lower because of the integral trigger guard, like the Spike's Crusader lower posted above.


Same, but I’ve been using Aero lowers because the bolt release roll-pin is a screw. It’s SO nice.

Thanks. Looks like it is discontinued, but I think that is a DD 4042? I like the concept.

I use Aero lowers because I can buy them at the LGS and they are good quality. X15 Milspec and M4E1 depending on the build. Aero uppers too, mostly ones without the forward assist.

If you know manufacturing (I do, with 25 years in), you can see how many OEM's use Aero parts. Stag is all Aero, for example.

Ideally, LMT Mars, Radian ambi, or ADM ambi, are the best right now, for me.
