    – Expo Arms Combat Series 10.3” Upper Receiver with XP-1215KM Muzzle Brake – ($469.99)

    Expo Arms’ Patrol Series Upper Receivers incorporate premium features like chrome-lined or nitride barrels, free-float M-LOK handguards, and optimized gas systems on T-Marked MIL-SPEC receivers. Combat Series Upper Receivers include all the outstanding features of the Patrol Series with an upgraded Combat Series handguard. Combat Series handguards feature a 7075-T6 barrel nut, staggered 45-degree M-LOK slots, top rail lightening cuts, and a dual-screw wedge system for maximum reliability and precision.

    The 11.5” Patrol Series Uppers and 10.3” Combat Series Uppers are available with two different muzzle configurations: A2 Flash Hider and Expo Arms’ exclusive XP-1215KM Muzzle Brake. Created in partnership with Forward Controls Design, the XP-1215KM is an extended single-chamber muzzle brake with KeyMo QD suppressor compatibility. While muzzle brake variants are slightly more expensive, all Expo Arms uppers are priced for affordability, making them an attractive option for any AR build.

    “Expo Arms has an established reputation of quality with our customers, owed to its strict manufacturing tolerances and commitment to 100% American manufacturing,” says Matt Okun, Senior Merchandising Manager at Primary Arms. “Expo Arms upper receivers build upon that commitment, and we know customers will be impressed by the design and craftsmanship of every product.”
