the billet style lower they introduced is better looking but nice to have some options for lowers that don't need a buffer tube.
The more important thing is that Brownells is selling a retro AR180 stock using a Sig-sourced folding 1913 knuckle. I sent their OEM partner the stock from a Sterling AR180 I have in maybe Oct/Nov and they 3D modeled it from that. They still have my stock and will be sending it back to me with one of the new versions out of the first batch.
I promised not to say anything but now that it's on the wall at SHOT, here are some pics from the show:
and the new Retro lower with a brace on it:
here's a pic of the "forged" style lower meant for a modern AR180 build using the BRN180 uppers (I think it's made by Aero based on the features shown on Brownells webpage)
