Product Description

Features

  • Steel construction
  • Set screw to retain takedown pin and detent for ease of installation
  • No peening or staking needed with the Anti-Rotation Castle Nut/End Plate design
  • Anti-rotate QD socket
  • Multiple sling attachment points
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.

"Fits my VFC 416D GBBR just fine. Great solution for attaching a sling plate.
by Steven T. on 07/31/2021
"The product itself is solid:
Made from steel, no burrs, cut to spec, choice of QD, Hook, or Wrap attachment, ambidextrous, and priced reasonability

HOWEVER:
This product is meant for real steel and you might run into compatibility issues (TM spec buffer tubes would likely not have an issue, but Ares spec buffer tubes has a high chance or a problem). I have an EMG Daniel Defense and EMG SAI GRY M4 platform (both G&P OEM guns) and I needed to 3D print spacers such that I could use this product correctly (without the spacer, the buffer tube was clipping the battery wires). You could dremel your old endplate into a spacer if you have the right tools – but that’s extra work some folks may not be comfortable with doing.
