- Integrated Quick Detach (QD) sling socket for versatile sling attachment options
- Machined from lightweight 7075-T6 aircraft-grade aluminum for superior strength

- Drop-in compatible with standard mil-spec AR-15 buffer tube receivers
Who This Is For
This end plate is ideal for AR-15 builders and enthusiasts who want a cleaner, faster assembly process without sacrificing reliability — whether you're building a competition rifle, a lightweight patrol carbine, or a custom showpiece where every detail counts. The gold finish makes it a natural choice for two-tone or themed builds that demand both function and flair.

Frequently Asked Questions
Do I still need to stake the castle nut with the Fortis K1 system?
No — staking is completely unnecessary with the Fortis K1 end plate system. The tapered castle nut is precision-machined to create an ultra-snug, self-seating fit against the end plate. Once properly torqued, the taper locks the nut in place mechanically, preventing any rotation or backing out under recoil without the need for staking, set screws, or any secondary retention method.
Is this end plate compatible with my existing mil-spec AR-15 lower receiver and buffer tube?
Yes. The Fortis Lightweight Enhanced End Plate is designed to work with standard mil-spec AR-15 lower receivers and commercial or mil-spec buffer tubes. It replaces your factory end plate and castle nut as a complete unit. Always verify your buffer tube diameter before ordering to ensure proper fitment, especially if you're running a non-standard or proprietary lower.
What type of QD sling attachment is supported by this end plate?
The Fortis K1 end plate features an integrated Quick Detach (QD) sling socket that accepts standard push-button QD sling swivels. This allows you to mount a single-point or two-point sling directly to the rear of your lower receiver for a clean, low-profile sling attachment — no separate QD adapter or additional hardware required.
