Geissele MK4 Rail
The 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 the user to tailor their platform to his or her unique needs.
Inner Diameter: 1.35"
Outer Diameter: 2.11"
Weight: 7” Rail - 9.7oz
BCM Mod 4B Medium Latch Charging Handle
Optimizing the contours into a snag-free profile that facilities immediate manipulation with and end user’s reaction side grip, the range of BCMGUNFIGHTER™ Charging Handles is available with both ambidextrous and MIL-SPEC controls. Redesigned to eliminate the load on the pivot pin (like USGI handle fitted with an extended latch) and keep the energy from charging close the centerline of the carbine/rifle, BCMGUNFIGHTER™ Charging Handles provides an larger interrupted engagement surface with a smaller silhouette.
