Geissele MK4 SMR Super Modular Rail, 13.5″ MLOK, Desert Dirt Color

Geissele MK4 SMR Super Modular Rail, 13.5″ MLOK, Desert Dirt Color

The Geissele Super Modular Rail MK4 is one of Geissele’s legacy rails that brought them to fame.

These rails have three sides of MLOK in the 3, 6 and 9 o’clock surfaces and another two sections of MLOK in the upper 45-degree surfaces. The MK4s also feature 1913 picatinny sections at the ends of the rail towards the muzzle.

The MK4 is installed using Geissele’s proprietary barrel nut, allowing easy installation and maintenance but also zero repeatability. The Geissele SMR is precision machined using 7000 Series Aluminum due to its strong, rigid and light properties, and is finished in durable Type-3 Hardcoat anodized.
