The Aim Sports MTMSG870 Modular M-LOK Rail System for Remington 870 transforms your shotgun into a highly configurable platform while keeping weight to a minimum. This monolithic aluminum rail stretches nearly the full length of the barrel, combining a 1913 Mil-Spec Picatinny top rail with generous M-LOK slots along the sides and bottom for streamlined accessory mounting.

Designed to fit most Remington 870 shotguns, this system installs with a straightforward bolt-on design and includes a front mag-tube barrel clamp for added stability. The wide ejection port opening maintains reliable operation, while the removable 6-shell holder keeps extra rounds close at hand for range sessions, training, or defensive setups. Aim Sports brings thoughtful engineering and practical innovation together in a rail system built for shooters who value modularity and efficiency.
