Shoots Nice
I decided to convert a long barrel 300blk to this. My first barrel swap. Everything went together great. Took her out to the forest and she shot right where I wanted and smoothly.

A diamond in the ruff
The quality of the machining and overall fit & finish is excellent. So how does it shoot right. Well I took some Hornady Black 75 gr BTHP and AAC 77 gr OTM and consistently got 1/2 MOA at 100 yards, as the barrel heated up the largest group was 1 inch @ 100 yards. Out to 500 yards, I was hitting a IPSC steel target 10-10 times. Hands down the best barrel purchase I've ever made.
US18” SPR Ballistic advantage barrel
Great barrel and shot very well.
USTack Driver
Arrived in perfect condition, this thing just SHOOTS. I've only shot the 77 gr Sierra BTHP because that's what I bought it for. Awesome value for the money....it's $175 on the BA website.
USGood looking barrel
Good fit and finish for my rifle-sized AR-build.
