Choose another barrel - New Frontier Armory New Frontier Ar9/40 Match Bbl 8" 1:16 40s&w Black

I realize for 40 caliber there’s not many choices. Don’t choose this one until they fix the problem. Barrel has a feeding problem maybe 1 out of 4 will feed in correctly. The rest jam up and put a crease in the brass ruining the casing. Comparing this barrel to my 9mm AR barrel from another brand, the 40 practically doesn’t have a feeding ramp explains why it jams so much. You’d think for the price you’d get decent product.
