The 13″ LO-PRO SLOPE NOSE M-LOK Free Float Quadrail was developed to accommodate the features of the 7.5″ LPSN quad rail to a longer 13″ version. The LPSN13 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 LPSN13 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 LPSN13 M-LOK make it the perfect choice for your AR-15 rifle build.
