So I've been interested in the .300 blackout round for a while now, and so I decided on a .300 blackout (.300blk for short) build for my deer gun for next season (at least that's my excuse for another gun build ), and parts are starting to roll in so I thought I'd post up a few pics. It will be built up as a pistol, and the lower was transferred as such until I file for and receive my stamp to go the SBR route. I'll update as stuff shows up.
