Great barrel! Review by Cal
Bought this barrel for a 300 BLKOUT Pistol build.
Shipped fast and arrived on time. Could not be more pleased with its performance. I was hitting close to target before I even began to adjust the irons. Great barrel, well built, very accurate. (Posted on 4/5/2019)
Superb BarrelReview by Bernard
I have had this Performance Series barrel over a year. It was used for a frankenbuild 300 BO pistol. Nothing fancy, mostly Aero parts and an ALG trigger with a Primary Arms red dot. The quality of the barrel is evident as soon as you unwrap it, with flawless machining and markings.
Once installed, I fired 1 subsonic through it unsuppressed to insure function and determine if the bolt would lock problem.

Off to the range, it was sighted for 50 yards with my handloads shooting a mixture of 147gr pulls and 110gr Hornadys', both using Little Gun and H110 powder. The pistol functioned flawlessly and this barrel's precision will exceed most people's ability. I easily grouped an inch or so without much effort shooting freehand. I next tried some VTX 110 factory loads and the accuracy was equally impressive. I have since purchased 2 other Performance Series BA barrels, a 16" in 300 BO set up to hunt hogs and an 18" 5.56 for a range toy.
Those barrels, like the 9", deliver the goods. I would recommend these barrels without hesitation. (Posted on 5/20/2017)
