Description
Product Overview
Shed unnecessary weight from your carbine without sacrificing strength or duty-grade reliability with the Ultralight QD Endplate for AR15 / M16. Tipping the scales at a featherlight 7.7 grams, this receiver endplate is precision-machined from solid 6061-T6 billet aluminum and protected with a hard-wearing MIL-SPEC Type III anodized finish.
To prevent the wear and tear common to all-aluminum sling mounts, this endplate features a press-fit, heat-treated 17-4 stainless steel QD sling swivel cup. This hybrid design gives ultra-lightweight build enthusiasts the ultimate combination of weight reduction, extreme rotation durability, and secure sling attachment for both MIL-SPEC and commercial carbine buffer tubes.

- Featherlight 7.7g Profile: Ideal for lightweight, competition, and minimalist AR-15 carbine builds.
- 6061-T6 Billet Aluminum Body: High-strength aircraft aluminum body with a tough MIL-SPEC Type III hard-coat anodized finish.
- 17-4 Stainless Steel QD Insert: Press-fit, heat-treated 17-4 SS QD socket prevents steel sling swivels from galling or wearing out the aluminum housing.
- Universal Tube Fitment: Compatible with all standard AR15 and M16 pattern lower receivers running MIL-SPEC or commercial carbine buffer tubes.

Frequently Asked Questions
Why is a stainless steel QD cup used instead of full aluminum?
Steel QD sling swivels can erode or deform softer aluminum sockets over time. Press-fitting a heat-treated 17-4 stainless steel cup into the 6061 aluminum body gives you the ultra-lightweight benefits of aluminum while maintaining steel-on-steel wear resistance where the sling swivel locks in.
Does this endplate come with a castle nut?
No, a standard AR-15 carbine castle nut is required for installation and must be purchased separately if you are not reusing your existing hardware.
Why might the QD socket color vary slightly?
Due to the high-temperature heat-treating process applied to the 17-4 stainless steel QD cup to achieve maximum surface hardness, minor natural color variations in the steel insert are normal.
Will this fit rifle-length (A2) buffer tubes?
No, rifle-length fixed stock buffer tubes do not utilize a castle nut or endplate. This item is designed specifically for collapsible stock MIL-SPEC and commercial carbine buffer tubes.
