Strike Qd End Plate, Si Ar-ul-mfep&acn-red End Plate & Anti-rotate Nut Gun Sock and tab position indicationThe si multi function end plate and anti rotation castle nut are designed to update and upgrade the often neglected castle nut and endplate system. While the traditional endplate and castle nut works extremely well in retaining your receiver extension, the peening of the castle nut is not conducive to rebuilding. With the vast amount of aftermarket support for the ar system today, we felt that there's a need for a secure system as adaptive as you are.
