AR-15 – Castle Nut & End Plate – QD – Enhanced
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Strike Industries Enhanced Castle Nut and Extended End Plate combo upgrades the rear of your AR-15 with a longer steel castle nut and an extended QD end plate that pushes the sling mount rearward. It is built to improve support on the receiver extension threads while giving you a cleaner, more useful sling interface.
Fitment
- Fits AR-15 receiver extension / buffer tube setups
- Includes QD sling socket on the end plate
- Black finish
What it does
It replaces the standard rear end plate and castle nut with a more robust and more feature-rich combo that supports sling mounting and cleaner rear-end geometry.
Why it’s worth it
Good upgrade for rifles meant to be used hard. Better rear sling location, better thread support, better look. No mystery there.
