Fortis Manufacturing, Inc.
The Fortis Lightweight Enhanced AR15 end plate is a thoughtfully engineered alternative to traditional castle nut assemblies. Built around Fortis's K1 system, this end plate uses a tapered design that seats and seals the castle nut automatically—no staking, no set screws, no ratcheting mechanism required. If you're building or upgrading an AR and tired of wrestling with conventional end plates or worrying about them loosening, this is a cleaner, more reliable approach that simplifies the back-end of your receiver extension.
The end plate is machined from 7075 T6 aircraft-grade aluminum, keeping weight minimal without compromising durability. The tapered castle nut fit is precision-tight enough that it locks in place on its own, eliminating the failure modes that plague looser designs. That means no backing out, no need to re-stake after shooting, and no risk of the nut gradually walking free under recoil. It's the kind of thoughtful engineering that prevents headaches down the line.
The included quick-detach socket makes installation and removal straightforward, so whether you're field-stripping for cleaning or swapping your buffer tube setup, you won't need improvised tools or your armorer's vise. The gold finish is cosmetic, but it pairs well with other anodized components if you're building a cohesive look.
