The 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. Enter the MFEP and ACN.
The MFEP and ACN offer an anti-rotate QD socket or sling loops built
in. The Anti-Rotation Castle Nut is specifically designed to work with
this end plate. Instead of peening the endplate to secure the castle
nut, a set screw fulfills this function to allow for multiple uses as
you upgrade, or update your build.
The Multi-Function End Plate is reversible, and has three integral
sling mounting options. A traditional sling loop, a loop for hook style
attachments, and a QD socket gives you the flexibility in using
whichever attachment you prefer.
