Have you ever wanted to build a 9mm AR? Most shooters do.The popularity of 9mm AR builds have reached far and wide in the firearms world. And the parts available from manufacturers for building an AR in 9mm have grown. ODIN Works is one of the best companies building barrels for this specific type of firearm. The ODIN Works 9mm Medium Profile 7.5″ 416R Stainless Steel Barrel takes advantage of the popularity of 9mm AR platforms. It comes in the super well-known 9mm Luger chamber to run inexpensive training ammo, hollow points, and custom loads. The 1:10″ twist rate is cut with button type rifling (meaning the 9mm bullet makes one full rotation every 10″ inches), it has the normal *1/2×28 thread pattern to fit most standard AR muzzle devices*, and the Medium Profile of the barrel keeps it rigid and helps with accuracy. Between the Colt magazine or a Glock magazine compatible AR9 lowers, either one would serve you well for your newest AR9 build. These awesome barrels are available in 7.5″, 10.5″, or 16.1″ lengths to build your AR9 in whatever size you need in your safe. Start your next Blowback-type AR build today with an ODIN Works 7.5″ 9mm Medium Profile Stainless Steel Barrel.

With multiple online reviews getting 5 out of 5 Stars, you can see why this barrel is a great choice for your AR9 build. And the AR-15Discounts Satisfaction Guarantee says if you’re unhappy for any reason, you can send it back to us within 30 days for a full refund.

*NOTE: Even though this barrel uses standard AR-15 1/2″x28 threads on the muzzle, you MUST BE SURE that you get an AR muzzle device that is made for a 9mm (Or larger) bullet to travel through it. Many AR muzzle devices are threaded to 1/2×28 but they are made for 5.56x45mm or .223 Rem. Trying to shoot a 9mm (.354″) bullet through a .223 (.223″-.224″) muzzle device will not end well. When you measure the hole at the end of the muzzle device, it should have a hole for the bullet to exit through that is larger than .354″ (9mm). Check it, then check it again. Don’t trust the package, check it yourself.
