Description
The Midwest Industries MI M-LOK QD Sling Attachment does one job and does it right: it turns any open M-LOK slot into a solid quick-detach sling point. If your handguard came bare or you want to move your sling forward for a better carry angle, this is the simple fix. It bolts straight to an M-LOK rail and gives your push-button QD swivel a clean home that doesn't spin or rattle loose on you.
The whole piece is machined from 6061 aluminum and finished in hard coat anodized matte black, so it holds up to real handling and blends right in with the rest of your setup. At roughly 0.6 ounce, you're not going to feel it on the gun, which matters when you're building a lightweight carbine and counting every ounce. It's also 100% made in the USA and backed by a lifetime warranty, which tells you Midwest stands behind the machine work.
Why the MI M-LOK QD Sling Attachment Holds Up
The QD socket here is fully supported and rotation-limited, meaning the swivel seats deep and stays put instead of flopping around. That's the difference you feel when you're transitioning the rifle across your body or running a course of fire. Folks who've mounted these consistently mention smooth QD operation and a fit and finish that's dialed in right out of the pouch.
Setting Up the MI M-LOK Sling Adapter
Installation is about as easy as M-LOK gets. The attachment hardware comes in the box, and you'll just need a small Allen wrench to snug it into an open slot on your handguard. Because the footprint is compact and the profile sits low, it leaves plenty of surrounding real estate free for lights, grips, or wherever else you want to run gear. Works with any standard push-button QD sling swivel, so whatever sling you're already running should drop right in.

Frequently Asked Questions
Does the MI M-LOK QD Sling Attachment come with the mounting hardware?
Yes, the attachment hardware needed to bolt it to your M-LOK rail is included in the box. You'll just want a small Allen wrench, typically a 3/32 inch, to install it. Once it's snugged down, it stays put.
What kind of sling swivel works with this adapter?
It's built for standard push-button QD sling swivels, which is what the vast majority of modern slings use. The socket is rotation-limited, so your swivel seats deep and won't spin around while you run the rifle. Most any QD sling you already own should drop right in.
Will this fit any M-LOK handguard?
It's designed to mount to any M-LOK compatible handguard or forend that has an open slot to spare. As long as your rail follows M-LOK spec, this adapter will bolt right on. Its compact footprint also leaves room around it for other accessories.
How much weight does the MI M-LOK QD Sling Attachment add?
Almost nothing. It tips the scale at roughly 0.6 ounce thanks to the machined 6061 aluminum build. If you're putting together a lightweight carbine, this is one of those additions you won't feel on the gun.
