Geissele Automatics Super Duty Center Tab MK16 Assembled AR-15 Upper Receiver - 9.3" - 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 9.3-inch MK16 Kit pairs the mil-spec Super Duty upper receiver with the 9.3-inch MK16 free-float handguard. This length hits the sweet spot for compact AR-15 builds, the short-configuration complement Geissele cites alongside the longer MK16 sizes in the URG-I program family.

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 to 11.5-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 a versatile choice for SBR builds, compact duty configurations, and pistol uppers where meaningful accessory space matters without the length penalty of a mid-length handguard.

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