Description
M-LOK slots are great for cutting weight and staying modular, but they leave you without a spot to hang a sling or clamp on a bipod that runs off a traditional swivel stud. That is exactly the gap this MDT adapter fills. It bolts a standard swivel stud right into any M-LOK slot on your chassis, handguard, or forend, so you can run the gear you already own without buying a whole new setup.
What the MDT M-LOK Swivel Stud Does Best
This is the go-to fix for anyone with a Harris-style bipod sitting in the closet and an M-LOK forend that won't take it. Drop the stud into a slot, snug down the included hardware, and you have a mounting point in a matter of seconds. It works just as well for slings, giving you a clean carry option on a precision rifle or an AR build. Because you can place it wherever an M-LOK slot lives, you get real control over balance and reach instead of settling for whatever position the factory gave you.
Built to Take Some Abuse
MDT machines the stud from 6061-T6 aluminum and finishes it with a hard black anodize, so it holds up to field use and shrugs off scuffs. It keeps a low profile too, so once your bipod comes off, the stud stays out of the way and doesn't snag on gear or your hands. Folks who run it tend to mention how sturdy and simple it is, which is about all you want from a part like this.
Fits a Wide Range of Setups
Since it uses the universal M-LOK interface, this stud plays nice with MDT chassis systems like the TAC21, LSS XL Gen 2, and ESS, plus the Oryx forend and pretty much any other M-LOK compatible handguard out there. If your rifle wears M-LOK, this gives it a swivel stud without any permanent changes. It ships with the mounting hardware you need to get it locked in and shooting.

Frequently Asked Questions
What will the MDT M-LOK sling swivel stud mount?
It gives you a standard swivel stud on any M-LOK slot, so you can hang a sling or clamp on a Harris-style bipod. This is a popular way to run a bipod you already own on an M-LOK forend that otherwise wouldn't accept it. It handles both jobs equally well depending on where you place it.
Is the M-LOK swivel stud hard to install?
Not at all. It drops into an open M-LOK slot and tightens down with the included hardware in a matter of seconds. No gunsmithing or permanent changes to your rifle are needed.
Will this fit chassis and handguards from other brands?
Yes. Because it uses the universal M-LOK interface, it fits MDT systems like the TAC21, LSS XL Gen 2, ESS, and Oryx forend, along with just about any other M-LOK compatible handguard or forend. If your rifle has M-LOK slots, this stud will work.
What is the swivel stud made from?
MDT machines it from 6061-T6 aluminum and finishes it with a hard black anodize for durability. That keeps it lightweight while still standing up to field and range use. It also sits low profile so it stays out of the way when your bipod is off.
