The LPSN7.5” M-LOK version, inspired by multiple beneficial features that shooters have requested and demanded from Phase 5 and other manufacturers. The slender design, longer nose, ease of installation and superior construction are some of the features that they designed into this 7.5“ M-LOK quad rail system. The LPSN7.5” M-LOK undergoes a rigorous extra de-burring process in order to ensure a smoother snag free finish. The details and level of care during the manufacturing of the rail make it the perfect choice for your Carbine or Pistol build. M-LOK is a modular locking accessory mounting system that is a direct attachment method for hard mounting accessories to a negative space mounting point. Designed by Magpul Industries as an evolution of the MOE® slot system used since 2007.
