Stern Defense SD AR-15 9mm 10.5" Melonite Threaded Barrel

Stern Defense AR Barrels Features The Stern Defense Barrel is machined from 4150 chrome moly steel a material chosen for its strength and ability to handle sustained firing without premature wear. A Melonite coating is applied over the steel adding corrosion resistance and reducing friction during cycling which helps extend the service life of the barrel. The 1:10 twist rate is matched to common 9mm bullet weights supporting stable accurate flight down range. At 10.5 inches the barrel is built for compact AR-15 9mm builds where a shorter overall length is the priority. Threaded 1/2x36 the barrel accepts a range of compatible muzzle devices giving shooters the flexibility to add a compensator flash hider or suppressor mount as their build requires. This threading is specific to 9mm AR platforms so it is designed to work with the muzzle devices already common in that ecosystem. The barrel is finished in black and manufactured entirely in the USA reflecting the quality control standards Stern Defense applies to its barrel production. For anyone building or upgrading a 9mm AR-15 pistol caliber carbine this barrel offers a durable accurate option backed by domestic manufacturing.
