- Tapered castle nut self-seats and seals without staking required
- Integrated Quick Detach socket for easy sling attachment and routing
- No set screws, no ratcheting system, and zero backing out under recoil

- Anodized matte black finish resists corrosion and wear in harsh conditions
Who This Is For
This end plate is ideal for AR-15 builders and serious shooters who want a clean, tool-friendly assembly that still locks down with confidence — whether you're running a competition rifle, a home-defense carbine, or a precision patrol build. It's especially well-suited for anyone who attaches a sling and wants a dedicated QD socket integrated directly into their lower receiver's buffer tube area.

Frequently Asked Questions
Does the Fortis K1 End Plate work with standard mil-spec AR-15 buffer tubes?
Yes. The Fortis K1 Enhanced End Plate is designed to work with standard mil-spec AR-15 buffer tubes and lower receivers. The included tapered castle nut threads onto any standard mil-spec buffer tube thread pattern, making it a straightforward drop-in replacement for factory end plates during any AR-15 build or upgrade.
Do I still need to stake the castle nut with this system?
No — that's one of the biggest advantages of the Fortis K1 system. The tapered castle nut is precision-machined to self-seat and lock into the end plate as it's torqued down, eliminating the need for staking entirely. This makes installation cleaner and allows the buffer tube to be easily removed in the future if needed, without damaging the lower receiver.
What size QD sling swivel is compatible with the integrated socket?
The integrated Quick Detach socket on the Fortis K1 End Plate accepts standard 1.25-inch QD push-button sling swivels, which are the most common size used on AR-15 compatible sling systems from manufacturers like Blue Force Gear, Magpul, and Vickers. Always verify your specific sling swivel diameter before purchase.
