The TacFire Mar078S QD End Plate is a US-made buffer tube cap designed to modernize your AR-15's rear end with quick-detach (QD) sling attachment capability. If you're running a tactical rifle, hunting rifle, or competition build, a quality end plate transforms how you deploy and manage a sling—no more fumbling with traditional fixed swivels or makeshift attachment points. This steel construction end plate handles both Mil-Spec and commercial buffer tube diameters, so it works with virtually any standard AR platform you're building or upgrading.
Built from solid steel and finished in black matte, the Mar078S offers a no-nonsense, durable platform for mounting quick-detach sling swivels. The matte finish resists glare and blends seamlessly with other tactical components. Whether you're setting up a precision rifle, a duty-style build, or a field gun for hunting, a QD end plate eliminates the need for permanent sling loops and lets you swap or adjust your sling setup in seconds.
Installation is straightforward on any AR-15 with a castle nut already in place—the end plate simply screws onto your existing buffer tube. It's a small upgrade that pays dividends in handling and ergonomics, especially if you're running your rifle hard or prefer the flexibility of quick-detach gear.

Yes. The Mar078S is compatible with both Mil-Spec and commercial diameter buffer tubes, covering the vast majority of standard AR-15 builds.
Any quick-detach (QD) sling swivel with a standard QD socket will mount directly to the Mar078S. You'll need to source a QD swivel separately if you don't already have one.
The end plate threads onto your buffer tube where a standard end plate would sit. Your castle nut must already be installed; the Mar078S simply screws on in its place.
No. You'll need to remove your current end plate and unscrew it from the buffer tube, then install the Mar078S in its place. It's a simple job and requires no gunsmithing.
