14.5” middy

Nice, I'm sure it'll run great. You've got a great BCG and the Geissele buffer/spring solution. And that's the heart of the rifle. As long as the receiver set is within spec, and the buffer weight is appropriate for the amount of gas it should run like a scalded dog.

👍 it’s soft as they get shooting suppressed or un-suppressed. Tbh there are better buffer solutions that aren’t proprietary but it was something that I wanted to try.

They aren’t advertised as FN barrels but the mountain series is done by FN https://www.rainierarms.com/rainier-...l-5-56mm-nato/

They are cheap because Rainier is clearing them out. I picked up an 18" CHF Mountain barrel at a great price.
