Phase 5 // 7.5" Lo-Pro Slope Nose (LPSN) Free Float Quad Rail - M-LOK

7.5" Lo-Pro Slope Nose MLOK™ Quad Rail (LPSN7.5MLOK)

The LPSN7.5” M-LOK version, inspired by multiple beneficial features that shooters have requested and demanded from us and other manufacturers. The slender design, longer nose, ease of installation and superior construction are some of the features that we 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.
