An amazing barrel for the price
As usual Faxon has created a really great barrel. I built a small ar-9 PCC with it and so far I’ve put 200 rounds through it with 0 failures. I love their regular AR barrels and was curious to see if Faxon could pull off a PCC barrel. They definitely can. I will probably get a slightly longer one as well since I know it’s going to be a dependable piece of gear.

best value out there
I spent quite a bit of time researching barrels before making my purchase. This is a lot of barrel for the money. I was very pleased with the quality and overall finish. I really liked the fact that the threads are 1/2x28 since I already have a suppressor mount in that size. The lightweight profile is a big plus also. While I haven't had a chance to shoot it a lot, I can say that function has been 100% and it has been plenty accurate for ringing steel plates with no trouble. I would highly recommend it for anyone building an AR based 9mm pistol or SBR.
