The BCM QD End Plate is a steel receiver end plate for AR-15 and M4 rifles with an integral quick-detach sling socket, fitting between the lower receiver and the castle nut.
A rear sling point that adds no length, no bulk and no extra clamp — it is simply the plate that was already there, made in steel with a QD socket in it.
Every AR-15 has a receiver end plate holding the takedown detent behind the buffer tube. Bravo Company USA's version replaces the plain stamped part with one machined from steel and bored for a push-button QD swivel, so the rifle gains a proper rear sling attachment without hanging an adapter off the stock or the tube. Because it is steel rather than aluminium, it accommodates staking, which is how a castle nut is properly secured against backing off.
It is the sort of part that costs little, fits once and is then forgotten about — which is exactly what you want from a sling mount. Pair it with a heavy duty QD sling swivel or the 1 inch D-ring swivel, neither of which is included.
Fits AR-15/M4-pattern lower receivers, sitting between the rear of the receiver and the castle nut on the receiver extension — including UK straight-pull AR-15 builds, where a solid rear sling point matters just as much. Fitting means backing off the castle nut, sliding the stock and tube back far enough to swap the plate, then re-torquing and staking the nut, so it is a stock-removal job rather than a bolt-on. A QD swivel is needed to use the socket and is sold separately.

No. The end plate provides the socket; the push-button swivel that clicks into it is a separate part. The <a href="/products/bcm-qd-sling-swivel-heavy-duty">heavy duty QD sling swivel</a> suits 1-1/4 inch slings and the <a href="/products/bcm-qd-sling-swivel-1-inch-d-ring">1 inch D-ring version</a> suits 1 inch slings.
No. The end plate is trapped between the receiver and the castle nut, so the castle nut has to be backed off and the receiver extension moved before the old plate can come out. Budget for re-torquing and re-staking the castle nut afterwards.
Steel takes staking, which is the accepted way of stopping a castle nut from backing off under use. It is also more resistant to wear at the sling socket, which is a point that takes load every time the rifle hangs off it.
Yes. The end plate is part of the lower receiver assembly and is unaffected by how the rifle is cycled, so it fits straight-pull AR-15 builds exactly as it fits any other AR-15/M4 lower.
