Geissele MK8 Rail
The SMR MK8 is one of the first rails available to utilize the Magpul M-LOK technology. These rails are designed to give the user full modularity while maintaining a strong and rigid platform. Maximum venting at the lower 45° quadrants create maximum heat dissipation and also dramatically reduces the rail's overall weight. Utilizing Magpul's M-LOK technology at the 3, 6, and 9 o'clock positions, as well as the upper 45° quadrants. The SMR MK8 is both versatile and modular, allowing the user to tailor their platform to his or her unique needs.

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.
