New 9mm Barrels from Rosco Manufacturing



Rosco Barrels


Rosco Manufacturing recently announced it was now producing 9mm barrels for the AR platform. The new barrels are part of the company’s Blood Line series and are available in a range of sizes: 5.5″, 7.5″ and 14.5″. According to information released by the company, these barrels were designed to meet the needs of competition, self-defense and suppressor equipped guns.

These barrels are made of 4150 CMV steel. According to the company, Rosco Manufacturing uses a proprietary rifling and polishing technique that is followed by a salt bath nitride treatment. Presumably, this is a treatment similar to the Tennifer and Melonite treatments used by a variety of other companies to increase the metal’s resistance to corrosion.

All three of the barrel lengths have a 1:10″ twist. Additionally, each of them are threaded (1/2×28) and have a 11˚ crown.

When it comes to price, barrel length matters. The shortest of the bunch has a suggested retail price of $105. The 7.5″ barrel carries an MSRP of $115. For the longest barrel, the 14.5″ version, you will spend up and pay $140 at full retail.

Rosco Manufacturing is based in Rhode Island. The company offers a range of barrel products including options for 5.56 NATO, .223 Wylde and 300 BLK builds.
