Hi All,
I'm not sure if anyone has seen this lower receiver, and initially, I thought, oh great, another featureless rifle for communist states.
But being a fan of traditional rifles and shotguns, I thought this lower would probably mate up and shoot comfortably with the 450BM.
with a short mag, it would be a nice streamlined design.

That's very interesting! Wonder how it would look with my 6.5 Grendel?

That is interesting. Looks like its only available as a complete rifle though. Makes the AR 50 state legal.
