Phase 5 Weapon Systems SQDEP Sloped QD End Plate AR15/M4 Black Aluminum

The Phase 5 Weapon Systems SQDEP Sloped QD End Plate for AR15/M4 is a purpose-built replacement for your stock carbine end plate, engineered to give you quick-disconnect capability without the extra weight. If you run a QD sling or need the ability to attach and detach accessories on the fly, this sloped quick disconnect end plate lets you do it cleanly—and at the 30-degree angle it's cut at, the QD mount sits naturally for sling orientation and operator comfort.

Built from black aluminum and made in America, the Phase 5 SQDEP fits mil-spec and commercial-spec receiver extensions, so it'll drop into nearly any standard AR-15, M4, or .308 AR-platform lower receiver. The 200 lb pull-force rating means your QD swivel won't fail under field use. This is the kind of upgrade that doesn't show up on paper—lighter than the factory alternative, fully compatible with standard push-button QD swivels, and it just works.

Whether you're building a duty rifle, a hunting platform, or setting up for tactical training, a quality QD end plate is one of those foundational pieces that improves handling and flexibility. Phase 5 has been refining AR components for years, and this end plate is a no-nonsense example of their engineering: it meets military specifications while actually solving the real problem—letting you attach and remove your sling (and other QD gear) without fumbling with standard end plate hardware.

Frequently Asked Questions

Will this end plate fit my AR-15 or M4?

Yes—the Phase 5 SQDEP is compatible with mil-spec and commercial-spec carbine receiver extensions found on standard AR-15, M4, and .308 AR-platform lower receivers. It also works with Phase 5 Pistol Buffer Tubes. If you're running a standard AR setup, this will fit.

What QD swivels and slings does it work with?

The SQDEP accepts standard push-button QD swivels. If your sling or accessory uses a standard QD attachment point, it will work with this end plate.

Why is the QD mount angled at 30 degrees?

The 30-degree angle positions the QD mount naturally for sling orientation and ergonomic operator comfort, so your sling hangs and releases the way your body expects it to.

How strong is the pull force?

The SQDEP is rated for a 200 lb pull force, meaning your QD attachment will handle heavy field use and remain secure under normal shooting and movement conditions.
