Description
The TROY M4 Rear Push-Button Sling Mount replaces your factory receiver end plate and gives you rock-solid attachment points for your rifle sling. Two ambidextrous QD positions mean you can mount your sling on the left or right side depending on your stance or mission setup. It's one of those upgrades that makes your rifle feel purpose-built rather than factory-issue.
What Makes the Troy M4 Mount Different
Troy built this thing from hardened aircraft aluminum, which keeps weight down without sacrificing strength. The stainless steel push-button release operates smoothly even when you're running gloves or working in low-light conditions. You get the included QD swivel right out of the box, so you're ready to mount a compatible sling immediately. The anodized finish matches mil-spec black receivers and holds up to field use without flaking or wearing through quickly.
Installation and Compatibility
This is a straightforward swap for your existing end plate. No special tools needed, and most builders can handle it in a few minutes. The mount sits low-profile and doesn't interfere with your buffer tube or castle nut, though you'll want to be careful during installation since the ambidextrous knobs on both sides do limit wrench clearance slightly. Works with standard mil-spec AR-15 and M4 platforms. Note that it may not fit properly on rifles with extended or modified receiver extensions, so double-check your setup before ordering.
Performance and Real-World Use
The Troy mount positions your sling attachment at the rear of the receiver where it stays out of the way during normal handling but gives you a solid mounting point for single-point or two-point slings. Owners consistently report excellent fit with minimal play, and the aluminum construction delivers the durability you'd expect from Troy's lineup. The QD swivel moves freely enough to prevent binding while remaining secure under load.

Frequently Asked Questions
Will this Troy M4 sling mount fit my AR pistol or short-barreled rifle?
Yes, this mount works on AR pistols and short rifles with standard mil-spec buffer tubes. However, it may not fit properly if your rifle has an extended or modified receiver extension. Check your specific setup before purchasing, as these variations can interfere with proper installation.
Can I use any QD sling swivel with this mount?
The mount comes with a heavy-duty push-button swivel, but it's designed to accept standard quick-detach sling swivels. Most quality QD slings from manufacturers like Magpul and Blue Force Gear will work, though fit can vary slightly between brands.
How difficult is installation of the Troy M4 sling mount?
Installation is straightforward and requires no gunsmith work. You remove your factory end plate and install this one using the same pins and castle nut. Most people finish in a few minutes, though the ambidextrous design does limit wrench clearance on the castle nut, making it slightly snugger to tighten than some alternatives.
What makes this better than the factory end plate?
The Troy mount provides two dedicated QD attachment points instead of a single fixed sling loop. The ambidextrous design lets you switch sides, and the hardened aluminum construction is tougher than most factory options while keeping weight minimal. You also get the included swivel, eliminating the need to purchase one separately.
