Description

The Magpul RSA QD is one of those simple parts that fixes a common headache: getting a clean, secure QD sling point up front on a rifle or shotgun that runs a Picatinny rail. It clamps directly onto any 1913 rail section and gives you a socket that works with the Magpul MS4 and just about any other push-button quick-detach sling. The attachment point sits at an angle that's dialed in for two-point sling carry, so the sling hangs and adjusts the way you'd want it to instead of fighting you.

What Sets the RSA QD Apart

Magpul builds this one from precision cast steel with a QPQ salt bath nitride finish, which is a fancy way of saying it laughs off corrosion and hard use while barely adding weight to your setup. There's an anti-rotation socket built in too, so your QD swivel won't spin and tangle your sling mid-carry. That little detail makes a real difference when you're moving around and don't want to babysit your gear.

Low Profile That Stays Out of the Way

One thing folks consistently point out is how unobtrusive this mount is. The beveled, low-slung design keeps it from snagging on slings or other gear, and it stays out of your line of sight whether you're running irons or an optic. It's also nice and narrow, so it eats up a single rail slot instead of hogging two like some of the wider mounts out there.

Built for Real-World Carry

This is a favorite among people who put miles on their rifles, from range regulars to guys who carry professionally. It installs quick, locks up tight on the rail, and holds firm until you decide to take it off. If you're setting up a two-point sling on an AR-15, M4, or a rail-equipped shotgun and want a forward mount that'll outlast the gun it's bolted to, the RSA QD is a smart, no-drama pick. Made in the USA.

Frequently Asked Questions

What slings work with the Magpul RSA QD?

The RSA QD is built for push-button quick-detach slings, including the Magpul MS4 and other QD sling swivels. As long as your sling uses a standard push-button QD swivel, it'll drop right into the socket. It's a go-to for setting up a two-point sling on the front end of your rifle.

Does the RSA QD fit on any Picatinny rail?

Yes, it mounts to any standard 1913 Picatinny rail section, so it works on most AR-15s, M4s, and rail-equipped shotguns and long guns. It's also nice and narrow, taking up a single rail slot rather than two. Installation is a quick, drop-in job with the included hardware.

Will the RSA QD get in the way of my optic or iron sights?

No, the low-profile, beveled design was made specifically to stay out of your sight picture and off your gear. It sits low on the rail so it won't obstruct your optic or irons and won't snag on your sling or clothing. That low profile is one of the features people bring up most.

How durable is the steel construction on the RSA QD?

It's cast from steel and finished with a QPQ salt bath nitride treatment, which gives it strong resistance to wear and corrosion. That means it holds up well to hard use and rough weather without adding much weight to your firearm. It also features an anti-rotation socket so your QD swivel won't spin and tangle the sling.
