The Ballistic Advantage Premium Series AR Barrel, .300 Blackout, 10.3 Inch (Ballistic Advantage part number BABL300007P) is machined from 416 stainless steel with a bead-blasted finish, giving builders a match-quality bare barrel for a compact 300 Blackout pistol or SBR project. Ballistic Advantage’s Premium Series barrels feature a nickel boron coated M4 feed ramp extension for smoother, more reliable feeding, and every barrel is both HP and MPI tested before it leaves the factory to catch flaws that visual inspection alone would miss. At 10.3 inches, this is a bare barrel with no receiver included, so it’s an ordinary Title I part to purchase; how it’s ultimately built determines whether NFA registration applies.

Frequently Asked Questions

Does buying this barrel require any special paperwork? No, it’s a bare barrel with no receiver included, an ordinary Title I part. Installing it on a shouldered, rifle-configured lower without proper registration would create an unregistered short-barreled rifle, so build it as a pistol or register it as an SBR.

What does HP and MPI testing mean? High pressure and magnetic particle inspection testing, both used to catch material flaws that wouldn’t be visible from the outside.

What is the feed ramp coating for? The nickel boron coating on the M4 feed ramp extension helps rounds feed more smoothly and consistently.
