BR 180

I never knew these upper receivers/rifles existed. Has anyone built one? What’s the preferred caliber and barrel length? I have an approved sbr lower so I can go either way.

I have been interested in them since they were announced, and now they have released even more configurations. The only thing that’s kept me from buying one is that it’s right hand charging. I prefer left-hand.

That being said, if you have an SBR lower, I’d say your best option is a 10.5 5.56 upper.

If you have an SBR Lower and a .30 suppressor, then a 8-10” 300BLK is money.

Also, keep in mind that if you are really going to utilize the BRN 180 upper, then you should really get an adapter that allows you to omit the buffer tube and add a 1913 rail adapter so you can have a folding stock

I like mine, I got rid of my HBF Galil and bought this in its place. I’m happy with the purchase and mor than likely I’ll get another but in 300 BO.

Here’s my 16 inch 5.56 I really enjoy it

I have tried on and it works great suppressed...but kinda gets real hot real quick. If it weren't so expensive and had more barrel length options for 300blk, I would've gotten a it instead of a 300blk SIG MCX
