10.5" Lo-Pro Slope Nose (LPSN10.5 MLOK) Free Float Quad Rail M-LOK™

10.5" Lo-Pro Slope Nose MLOK™ Quad Rail (LPSN10.5 MLOK)

The 10.5" LO-PRO SLOPE NOSE M-LOK Free Float Quadrail was developed to accommodate the features of our 7.5" LPSN quad rail to a longer 10.5" version. The LPSN10.5 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 and 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, superior construction and finish quality are some of the features that we designed into this system. The LPSN10.5 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 LPSN10.5 M-LOK make it the perfect choice for your AR-15 rifle build.

True-Fit Technology utilized on the LPSN15™

True-Fit Technology utilized with the LPSN10.5

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.True-fit
