B5 Systems QD Receiver End Plate for AR-15/LR-308 - Durable Steel Matte Finish

The B5 Systems QD Receiver End Plate for AR-15/LR-308 is a purpose-built steel alternative to standard buffer tube end plates—designed for shooters who want a quick-disconnect attachment point for single-point slings. This one-piece steel construction is engineered for real durability: limited rotation geometry keeps your sling secure and predictable, and the commercial manganese phosphate finish stands up to field use and corrosion. Made in the USA, it's the kind of no-nonsense part that rewards a good install and keeps working.

If you're running a tactical rifle, a precision .308, or any AR-pattern upper on a commercial tube, this end plate gives you a solid QD mounting point without the extra bulk or complexity of aftermarket receivers. The limited-rotation design means your sling attachment stays where you put it—no spin or drift during movement or transition. Proper staking during installation locks it down for the long haul.

Whether you're setting up a duty rifle, a competition gun, or a workhorse hunting platform, having a reliable single-point sling interface matters. The B5 QD end plate is a straightforward, proven solution that fits your existing lower receiver and buffer tube without additional tools or modifications.

Frequently Asked Questions

Will this B5 Systems QD end plate fit my AR-15 or .308 rifle?

Yes, this end plate is compatible with both AR-15 and LR-308 rifles that use commercial-diameter buffer tubes. Verify your lower receiver is configured for a commercial tube before ordering.

What's the advantage of limited rotation on an end plate?

Limited rotation keeps your single-point sling attachment point from spinning or rotating freely. This means your sling stays indexed the way you set it, reducing unpredictable movement during carry or deployment.

Do I need special tools to install this?

Proper installation involves staking the end plate to the tube to lock it in place permanently. You'll need a small punch and a way to stake the three detents. Do not attempt to use this end plate without proper staking.

Is this made in the USA?

Yes. B5 Systems manufactures this end plate in the United States.
