The 15" LO-PRO SLOPE NOSE M-LOK Free Float Quad Rail was developed to accommodate the features of their 7.5" LPSN quad rail to a longer 15" version. The LPSN15 M-LOK was inspired by beneficial features that shooters have requested and demanded from us and other manufacturers. 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. The slender light weight design, longer nose, ease of installation and superior construction and finish quality are some of the features that we designed into this system. The LPSN15 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 LPSN15 M-LOK makes it the perfect choice for your AR-15 rifle build.

TRUE-FIT TECHNOLOGY UTILIZED WITH THE LPSN15™

Phase 5’s True-fit™ technology was developed to secure the rail system onto the barrel nut with an accurate and solid full contact method around the entire surface area. The Phase 5 Weapon Systems Inc. True-fit™ rail attachment system gives the operator peace of mind and confidence that the system will not move or come loose. This is accomplished with 6 screws that form the rail with our True Fit feature around the barrel nut without distorting or pinching the rail at the bottom like in other rails on the market. Phase 5’s True-fit™ rail attachment system allows for the repeated removal and reinstallation of the rail without fatigue.
