Phase 5 13" Lo-Pro Slope Nose LPSN Free Float
Choose Quad Rail or M-LOK for your AR15 AR-15
The Phase 5™ LPSN™ was developed as an improvement to our previous quad rail. The new LPSN™ 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 LPSN™ make it the perfect forearm choice for your Carbine or Pistol build.
ALSO AVAILABLE IN M-LOK (CHOOSE STYLE)

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.
