Description

If you’re looking for the perfect AR-15 upper chambered in .300 BLK, you’ve found it. With a 10.5” mil-spec barrel made from 4150 CMV and a nitride finish, you’re going to get maximum velocity and performance with this compact upper.

This barrel features a nitride coating to dramatically increase barrel length while retaining MOA precision. Nitride coatings afford the same benefits as chrome lining, minus the loss of accuracy. An A3 mil-spec upper receiver finishes off this kit with a Full-Auto (M16) bolt carrier group. Ships test-fired with a Lifetime Warranty.
