Ballistic Advantage 8.3" 9MM Modern EPC Series AR-15 Barrel 1:10 TwistThis Ballistic Advantage EPC Straight Profile Modern Series Barrel is machined from 4150 CrMoV steel with a QPQ Corrosion Resistant Finish and 1/2-28 x .4" full profile threads.Features Designed to work with both Colt/RR and Glock-style AR builds. Compatible with standard mil-spec uppers. Numerous dedicated 9mm upper options work. Requires the use of a unique magwell conversion (Colt/Rock River style) with UZI mags or a dedicated 9mm lower with Glock mags. A 9mm round on an AR-15 platform operates by blowback and does not require a gas block or gas tube. Threaded 1/2x28 instead of 1/2x36 to give you greater versatility when choosing a suppressor. Integrated feed ramp and barrel extension. Since the "barrel extension" is an integral part of the barrel, the length stated is the true overall length. For example, an 11" 9mm barrel has the same outer dimensions/length as a 10.5" 5.56 barrel. Enhanced Feed RampNotes A standard 1/2x28 flash hider will not have enough clearance for a 9mm round to pass. Before installing a muzzle device, ensure that a 9mm round will drop freely through the bore of the muzzle device.Made In the United States of America
