Description
Running a single-point sling on your AR is one of those upgrades that just makes the rifle feel right in your hands, and Blackhawk's Universal Single Point Sling Adapter is a simple way to get there. It replaces the receiver end plate on any AR-15, M4, or M16 with a collapsible stock, adding a centered attachment loop that lets you clip in a single-point sling and keep the gun tight against your body when it's slung.
What the Blackhawk Single Point Adapter Does Right
The standout here is the fully ambidextrous design. Instead of two loops sitting off to the sides where your support hand keeps catching on them, this one puts a single loop at the rear center of the buffer tube area. That means it works the same whether you shoot lefty or righty, and there's nothing sticking out to snag or dig into your hand during transitions. It plays nice with most conventional sling hooks, so you're not locked into one specific sling brand to make it work.
Fitment for Your AR Sling Adapter Setup
This piece is built for AR/M4/M16 platforms running a collapsible stock, and it slots in where your factory end plate currently sits. Worth knowing up front that it may not fit some Colt rifles, so if you're building on a Colt lower it's smart to double check before you tear things down. The finished metal construction keeps it durable and low-profile, and it tucks in flush against the back of the receiver so your stock can still fully retract.
Installation Notes Before You Start
Swapping it in means pulling the castle nut off your buffer tube, so you'll want a proper armorer's wrench on hand. Folks who've installed it point out that if your castle nut has never been off, it can take some muscle the first time, but the adapter itself drops right into place once you're there. For anyone doing their own AR builds or upgrades, it's a quick job that pays off with a cleaner, better-balanced carry setup.

Frequently Asked Questions
How does the Blackhawk single point sling adapter install on my AR?
It replaces the receiver end plate that sits behind your collapsible stock, so you'll need to back off the castle nut to swap it in. An armorer's wrench makes the job easy, and once the nut is loose the adapter drops right into place before you retorque everything. If your castle nut has never been removed, expect it to take some effort the first time.
Is this sling adapter truly ambidextrous?
Yes. The loop sits at the rear center of the receiver rather than off to one side, so it works identically for left-handed and right-handed shooters. That center placement also keeps the mount out of the way of your support hand during transitions.
Will the Blackhawk sling adapter fit any AR-15?
It's designed for AR-15, M4, and M16 platforms running a collapsible stock, which covers the vast majority of modern rifles. It may not be compatible with some Colt rifles, so if you're working on a Colt lower it's worth confirming fitment before you start the install.
Do I need a specific sling to use this adapter?
No, it accepts most conventional single-point sling hooks, so you're not tied to one brand. Just make sure you're pairing it with a single-point sling rather than a two-point setup, since this adapter provides one centered attachment point for hanging the rifle flat against your body.
