I was looking for a 1/8 twist mid length 4150 QPQ barrel for a build and found this one and it’s perfect! Zeroing in my sights this barrel was very accurate!

Do your research and you will see Faxon barrels consistently show up among the best. Their products undergo vigorous quality control and it shows. I got perfect fit with the M4 feedramp and upper receiver. I’m very happy my purchase.

I don't have any feedback on the barrel, I"m still in the process of building out my gun, but I have bought the barrel on the reviews I've read elsewhere and I'm looking forward to seeing how far I can push the lead down range. I chose this barrel because of Faxon's reputation, the weight and the fact that it uses both the gunner and pencil profile in the design. We'll see how accurate it is soon.
I have bought a lot of my components including the upper and hand guard at AT3 and I'll keep coming back.
I bought a econo model A/R with a 1.9 Wylde barrel and got decent groups with 55 gr. at 100 yards but want to shoot out to at least 500 yards. This Faxon gunner barrel gave me tighter groups at 100 yards and gave me an acceptable group at 500 yards. With a little more practice I am very confident I can obtain my goal. The barrel makes a huge difference.
