Ballistic Advantage Modern Series 9mm AR-15 Barrel 5.5" Straight Contour - 1/2x36

The National Firearms Act regulates the configurations of some firearms assembled with barrels under 16” long. Know the NFA laws in your state before purchasing this item.

The Ballistic Advantage Modern Series barrel is combines the durability and strength of 41V50 chrome moly vanadium steel with the exceptionally corrosion resistant salt bath nitride treatment. This provides not only an impressive barrel life, but ensures excellent accuracy and an affordable price.

This 5.5" straight contour barrel is chambered for 9x19mm Luger ammunition and threaded for 1/2x36. This barrel will require the use of a magwell conversion (Colt/Rock River style) with UZI magazines or a dedicated 9mm lower with Glock magazines.

As the barrel extension is an integral part of this barrel, the stated length is the actual overall length of the product. For example, an 11" 9mm barrel will have the same overall length as a 10.5" 5.56 NATO barrel.

NOTE: Before installing a muzzle device, ensure that a 9mm round will drop freely through the bore of the muzzle device to avoid catastrophic failure.
