The TacFire AR-15 QD End Plate (brand part no. MAR078-S) is a full steel end plate that adds a quick-detach sling swivel attachment point to the rear of your lower receiver. Made in the USA, it’s compatible with both mil-spec and commercial buffer tubes, so it drops onto most AR-15 builds without hunting for a specific fit. The QD socket lets you attach or remove a compatible sling in seconds instead of threading a loop through a fixed swivel. It’s a straightforward upgrade for anyone who wants a QD sling mount without swapping the whole buffer tube or stock.
