Description

A sling changes how you carry and shoot a rifle, and the mounting point matters just as much as the sling itself. B5 Systems built this QD end plate to give you a clean, integrated attachment spot right at the rear of the receiver, with none of the extra bulk that comes from bolting on a separate mount. It swaps in where your factory end plate already sits, so you keep your setup tidy and low profile.

What Sets the B5 QD End Plate Apart

The whole piece is machined from a single chunk of steel, which is what lets it take proper staking and hold up for the long haul. The QD socket is anti-rotational, meaning your swivel gets a limited range of movement instead of spinning freely. That keeps the sling from twisting up on you and helps the rifle sit consistently against your body whether you are shouldering it or letting it hang. The socket works the same for right or left handed shooters, so it fits however you run your gun.

Finish and Fit on the B5 Systems End Plate

B5 gave it a mil-spec manganese phosphate finish that shrugs off corrosion and wear, the same kind of coating you would expect on a hard-use duty part. It measures about 0.35 inches thick and weighs roughly half an ounce, so it adds a sling point without adding any real weight to the build. Made in the USA, it plays nice with all mil-spec receiver extensions on both AR-15 and AR-10 lowers.

Getting the B5 QD End Plate Installed

Installation is straightforward if you have done buffer tube work before. You will pull the buffer and spring, remove the stock and receiver extension, back off the castle nut, and swap the old plate for this one before torquing everything back down and staking the nut. It is a great pairing for a single point or convertible sling, and it is one of those small upgrades that makes the rifle noticeably easier to live with.

Frequently Asked Questions

Does the B5 QD end plate come with a QD swivel?

No, the end plate provides the socket but the QD swivel is not included. You will need a standard push-button QD sling swivel to attach your sling. Most common swivels drop right into the socket.

Will this fit my AR-15 and AR-10 buffer tube?

Yes, it is designed to work with all mil-spec receiver extensions, so it fits both AR-15 and AR-10 lowers running a standard buffer tube. If your build uses a commercial-spec or otherwise non-standard tube, double check your setup before installing.

Is the QD socket ambidextrous?

The anti-rotation design works the same for right and left handed shooters. It gives the swivel a limited range of movement rather than letting it spin freely, which keeps your sling from twisting no matter which side you run it on.

How do I install the B5 Systems end plate?

You will remove the buffer, spring, stock, and receiver extension, then back off the castle nut to swap in the new plate. After reinstalling and torquing the castle nut back down, stake it to keep everything locked in place. The one-piece steel construction is built to take that staking for a lifetime of use.
