13" lo-Pro Slope Nose (LPSN13) Free Float Quad Rail


CLEARANCE ITEM: includes 2X LPSN-smPIC (picatinny sections) and 1X MHS-DT-BLK (Mini HandStop) with every purchase.

The 13-inch LPSN Quad Rail was inspired by lots of 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 system. Another development feature is the finish quality. The LPSN 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 LPSN13 make it the perfect choice for everyone.

Built-in QD mounts with internal stops.

True-Fit Technology utilized with the LPSN13

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
