LanTac USA RPS End Plate & Castle Nut, Black Nitride - 01-UP-RPS

The LanTac RPS is an end plate and castle nut assembly that eliminates the need to stake the castle nut after installation. It features a ratcheted tooth and arm machined into the anti-rotation plate that registers with aggressive grip pattern grooves on the enhanced castle nut to retain it in place. The assembly also provides a QD sling attachment point directly below the buffer tube.
