Geissele 13.5" Smr Mk16 Mlok Blk

The Geissele 13.5" SMR MK16 MLOK BLK is a precision modular rail system engineered for AR-15 platforms demanding maximum performance and reliability. Built for operators, competitive shooters, and military professionals who require lightweight yet rigid accessory mounting, this rail combines proven engineering with modern ergonomics. At 1.38 lbs, it delivers the strength-to-weight ratio critical for extended missions, CQB engagements, and competition shooting where every ounce impacts handling and fatigue.

The Super Modular Rail MK16 employs Geissele's updated barrel nut design—a proven platform trusted across law enforcement and military units—ensuring rock-solid consistency and zero deflection under tactical loads. The MLOK (Modular Lightweight Mounting System) slots provide uncompromised mounting flexibility for optics, lights, and vertical grips without proprietary hardware limitations. Anti-rotation tabs lock the rail to your upper receiver, eliminating shift during recoil and aggressive maneuvers, while the 13.5" length balances sight radius, accessory real estate, and overall weapon length for both short-barreled and mid-length configurations.

Operators running 10.5" to 16" upper receivers will find the MK16 ideal for maximizing rail coverage without excessive overhang or weight penalties. Installation is straightforward—the barrel nut interface accepts standard AR-15 uppers, and removal for maintenance requires no special tools. The anodized black finish resists corrosion in field conditions while maintaining low reflectivity. Whether outfitting a duty rifle, precision platform, or carbine build, the Geissele 13.5" SMR MK16 MLOK sets the standard for modular rail systems where rigidity, adaptability, and operational durability matter.
