Finally got my stamp back and finished my 1st SBR build. It's registered as a 300BLK (picture with the quad-rail) but I've also got the 5.56 upper ready to go. I've got a little work left to do but I'll have a dedicated .22LR upper as well for it.
I'll probably swap out a few parts but here it is so far...just wanted to share
