Selling a Gen 2 (2.5) BRN180 Upper in 300blk. Has maybe 200 Rounds through it. I also have the folding stock and picatinny adapter I used for my sbr build. This is a fantastic upper, shoots great as you'd expect. I've had it for maybe a year, built it for a truck gun setup but went a different route.

These are tough to find, no longer available. Asking $900 with folding stock and adapter
