AR-15 – Receiver End Plate & Castle Nut – QD / Sling Loop – Multi-Function End Plate
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Strike Industries Multi-Function End Plate with Anti-Rotation Castle Nut gives your AR-15 a cleaner sling mounting setup without the usual staking-only one-and-done headache. Strike builds this setup with an anti-rotation QD socket, integrated sling loops, and a matching anti-rotation castle nut that uses a set screw system instead of traditional peening.
This is a receiver extension end plate and castle nut combo for AR-15 pattern rifles. It is built for builders who want a reusable, cleaner-looking setup with practical sling mounting options already baked in.
Fitment
- Fits AR-15 pattern lower receivers using a standard carbine receiver extension setup
- Designed to pair with the included Strike anti-rotation castle nut
- Black finish
What it does
It replaces your standard end plate and castle nut with a more feature-rich setup that gives you rear sling mounting options and a reusable anti-rotation retention system.
Why it’s worth it
You get built-in rear sling options, a clean upgraded look, and a castle nut setup that is easier to reuse when you change buffer tubes or rework a build later. Less caveman staking drama. More practical function.
