This a very well finished barrel ,a work of art really. I have only shot it a little to sight it in,l have a red dot on it so it is hard to test accuracy at 100 yds. but it is accurate for a red dot.

Great Quality and Accurate

I replaced a PSA pencil barrel with this barrel. The SOCOM contour added a little more weight but the groups went from 3"+ @ 100 yards to the 1" range @ 100 yards. I highly recommend this barrel.

Good starter barrel

This is a good barrel if you’re starting an AR build. No issues so far. Only con is that its a bit on the heavy side for my liking. Other than that I would recommend and buy it for myself again.
