Geissele Automatics Super Duty Center Tab MK16 Assembled AR-15 Upper Receiver - 10.5" - BLEMULA

Note: This is a cosmetic blem unit — color and finish will vary and product images may not fully represent what you receive, but function is unaffected.

The Geissele Automatics Super Duty 10.5-inch MK16 Kit pairs the mil-spec Super Duty upper receiver with the 10.5-inch MK16 free-float handguard. This length gives builders the core upper assembly for a compact SBR or pistol build, centered on the same battle-proven MK16 free-float handguard adopted by USASOC for the URG-I program.

Features:

• Full-length M1913 Picatinny top rail with M-LOK slots on all four quadrants
• Anti-rotation tabs and set-screws hold zero under sustained fire
• Super Duty upper forged from 7075-T6 aluminum, machined to mil-spec tolerances
• M4 feedramps, milled T-marks, dust cover, and forward assist
• Type 3 hardcoat anodize for corrosion and wear resistance
• Compatible with mil-spec BCGs and .250 takedown pin lowers — best paired with 10.5-inch barrels

The handguard's anti-rotation tabs and set-screws keep it locked to zero under hard use, and the Center Tab barrel nut design matches the system used on fielded USASOC URG-I uppers. A complete build still needs a barrel, BCG, charging handle, and muzzle device. Color shade variance between matched components is normal and expected. It's ideal for short-barreled rifle builds, duty pistol uppers, and compact patrol configurations where the handguard length allows suppressor use without compromising maneuverability.

Geissele Automatics supplies precision components to U.S. military units and civilian builders, with manufacturing entirely in-house at their North Wales, Pennsylvania facility.
