Most Recent Reviews good looking barrel that works nicely by Jrobe, Verified Owner, June 11, 2024
I bought this barrel for a budget build, so my expectations weren't super high. But the barrel i received seems to be well made and has no visual flaws, so im happy with it.
Most Recent Reviews MID-LENGTH GAS SYSTEM, NOT CARBINE by Stephen Fallis, Verified Owner, April 14, 2024
The info on this listing states the carbine gas system is optimal, but the carbine gas tubes (at least the Aero Precision tube) is not long enough. You will need a mid-length tube for this barrel.
Most Recent Reviews Solid Value Piece by Stephen Fallis, Verified Owner, April 3, 2024
Not the flashiest or most top-grade barrel, but you can do much worse. You can do better, but also waaay worse. Especially for that price point.
