Quad Rail: The LPSNx15 was developed as an improvement to our previous quad rail. This rail was inspired by lots of beneficial features that shooters have requested and demanded from us and other manufacturers. The LPSNx15 undergoes a rigorous extra de-burring process to ensure a smoother, snag free finish. The details and level of care during the manufacturing of the LPSNx15 make it the perfect choice for your Rifle build.

Muzzle Device: The 2 large (FAT) ventilated baffle sections and chambers create the compensation needed to reduce the overall recoil felt by the shooter. The FATman Hex Brake includes two top ports machined at a 20 Deg. forward directed angle. These top ports help direct the energy of the spent gas in a manner that maintains a flat consecutive result shot after shot. The design of the FATman Hex Brake allows the first chamber wall to sit as close to the barrel crown plane as possible. This design element was included to maintain the full accuracy of the barrel.
