Green Mountain barrel blanks..... Blah. OK, so to be fair; what have you heard about Green Mountain? Longevity? Accuracy?
5.56, and 300blk
I have a 12.5" right now if interested. I've been running them on my SBR for reliability, and it runs like a charm.
I will start a barrel thread in the IP section in the next day or so. it will be open for discussion, for things you would like to see in the 5.56, and 300blk realm.
OK, so i opened this for Double D Armory, LTD specific barrels discussion: https://www.ar-15.co/threads/124987-...ee-for-barrels
