Geissele Super Modular Rail MK4 M-LOK Handguard - 15, DDC

Geissele Super Modular Rail MK4 M-LOK HandguardThe Super Modular Rail (SMR) MK4 M-LOK is Geissele's ultra-lightweight M-LOK option. These rails are purpose-built and feature integrated M1913 Picatinny rail sections at the fore of the rail in the 3, 6, and 9 o'clock positions. Maximum venting for heat dissipation also dramatically reduces the rail's overall weight, while maintaining its same strong and rigid platform. Utilizing Magpul's M-LOK technology at the 3, 6, and 9 o'clock positions, as well as the upper 45 quadrants. The SMR MK4 is both versatile and modular, allowing users to tailor their platform to their unique needs.The SMR MK4 also features Geissele's proprietary 2.25 long barrel nut. This increases the surface contact where the rail interfaces with the receiver and creates a platform that can be trusted to be straight and true throughout the entire length of the free-floating rail. This increases accuracy and zero repeatability during disassembly and reassembly when performing maintenance.Specifications Model: MK4 Height: 2.3" Length: 9.3",13.5", or 15" Color: Black or DDC Inner Diameter: 1.35" Outer Diameter (DAQ*): 2.11" Installed Weight (w/Hardware) 9.5": 11.0 oz 13" - 14.1 oz 15" - 15.4 oz
