The AR-9 4.5" Pistol Upper is designed for compact performance and reliable operation in your 9mm AR-9 pistol build. Featuring a heavy-profile 4.5" barrel, this upper delivers excellent durability and performance. The upper is finished off with a micro flash can compensator, perfect for reducing muzzle flash while enhancing accuracy and recoil management. Whether you’re building your pistol for home defense, range shooting, or adding it to your AR platform collection, this upper assembly offers everything you need to get your build started.
The blowback-operated system ensures reliable cycling with Glock or Colt-style lowers. The sick side receiver is a billet aluminum design, anodized for durability, and lacks a forward assist and dust cover to streamline the build. The upper includes a free-floating 4" slim profile M-LOK rail, which provides flexibility for mounting accessories such as lights, lasers, or grips.
The 8620 steel ramped BCG is milled to perfection for smooth cycling and is compatible with Glock or Colt-style lower receivers. The mil-spec charging handle allows for effortless operation, ensuring smooth and efficient cycling every time.
