The SLR Rifleworks Enhanced Castle Nut and Endplate is a premium endplate solution. Featuring Melonite finished 4140 steel on both the castle nut and the endplate, it is compatible with all multi position buffer tubes.  The end plate has a limited rotation QD socket while the dimpled castle nut offers secure retention without the need for staking.

Includes castle nut, receiver end plate, and hardware. Two set screws on the end plate secure the castle nut by lining up with the dimples. This system allows for easy dissasembly and repeated use of nut and end plate.
