Product description
Armaspec “No Stake” Castle Nut and QD End Plate Combo Eliminates Staking While Adding Quick Disconnect
Features
- Patented self-retention castle nut eliminates staking and thread locker
- Integrated QD sling attachment point on end plate
- Tool-free castle nut installation and removal
- Integrated set screw for easy detent installation
- Made in USA from premium aluminum alloys
This combo solves two common AR build problems – loose castle nuts that require permanent staking and the need for additional sling mounting hardware. It works exceptionally well for tactical applications requiring rapid sling transitions and for builders who want professional results without gunsmith modifications. The combination of self-retention castle nut technology with an integrated QD mount sets it apart by providing both secure buffer tube retention and versatile sling attachment in one complete package.

Customer reviews 1
Verified buyerI have another one waiting for a different build that I tried just to see if it was one-off issue but this appears to be how the nut works. I tried the same with both a Strike Industries enhanced buffer tube and an Aero Precision enhanced buffer tube, same stiffness issues. Maybe a basic milspec buffer would work differently but I don't have one available.
