Excellent barrel by Chris O., September 15, 2020
I’ve had this barrel for over a year now and it’s fantastic. It’s sub moa, looks great and came professionally packaged. Couple this barrel with a SLR or Rosco gas block (also made by SLR) and you’ll never have any issues.

Very accurate by Jr, Verified Owner, January 29, 2022
Theses are sturdy very accurate barrels, I have the 13.7 and 14.5 barrels and they make solid builds. I use them when ever I have a new build. The .223 Wylde barrel is perfect for a carbine class with ammo availability what it is now days.
