Questions & Answers
Will this barrel work with an aero upper with m4 feed ramps? Manufacturer Answer

Yes, this barrel will work with an upper that has M4 feed ramps cut, but the "big bore" feed ramp on the barrel extension will not line up with the M4 cuts. This should not impact the function of the rifle.

Excellent Barrel for the Money by Gator D, Verified Owner, July 6, 2021
Purchased this barrel for a deer rifle build. Fit & finish were excellent. Accuracy has been very good on the range sighting in the scope and one shot, one deer to the freezer this past deer season.

Insanely light by Mark Kennedy, March 25, 2020
Coming in at 1-1/2 pounds, this Faxon pencil barrel is a fantastic way to shed weight for an AR build. It was a very snug fit into the upper receiver, eliminating the need for a bedded compound. I can’t wait to take it hog hunting.

350 Legend by CSadler, November 11, 2019
Great barrel for the price. Very accurate but you may have to try a few different brands of ammo to find what shoots the best. Mine shot the federal the best but I only tried the Winchester and Federal.
