Geissele Automatics Super Duty Center Tab MK16 Assembled AR-15 Upper Receiver - 15" - DDC - 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 15-inch MK16 Kit pairs the mil-spec Super Duty upper receiver with the 15-inch MK16 free-float handguard. This full-length configuration of the USASOC URG-I upper platform gives rifle-length AR-15 builds maximum accessory real estate and the most forward support-hand position in the MK16 lineup.

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 16-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. The 15-inch length suits precision duty rifles, competition AR-15 builds, and patrol configurations that benefit from an extended support-hand position and maximum accessory coverage.

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