The Blemished IX 7.5-inch Carbine-Gas 1:10 9MM AR-9 Freefloat M-Lok Handguard Pistol Assembled Upper Receiver is an ideal choice for gunsmiths who value precision and functionality.

The 1:10 twist rate ensures optimal stability and accuracy, while the 9mm Flash Hider A2 Bird Cage reduces muzzle rise.

The upper receiver is constructed from billet aluminum, paired with a robust 7" M-LOK freefloat handguard in black, which includes a full top Picatinny rail for accessory mounting. Included is the Northtac Ronin P-11 Red Dot Sight, featuring a 20mm objective, a 1x magnification, and 0.5-MOA click adjustments for precise targeting. The combination of these features makes this upper receiver set a functional addition to any 9mm AR platform.
