Description
Getting a QD sling onto an M-LOK forearm shouldn't be a project, and the GrovTec Flanged Push Button Base makes it about as simple as it gets. This little adapter drops a push-button QD swivel socket right onto any open M-LOK slot on your handguard, giving you a clean, low-profile attachment point exactly where you want it. Because it's the non-rotating version, the base holds the swivel steady instead of letting it swing freely, which is the setup a lot of folks prefer for a two-point sling that needs to stay tidy against the rifle.
What Makes the GTSW193 Base Worth Bolting On
GrovTec builds this one from precision CNC-machined aluminum and finishes it with a Type-III hard anodized coating in black. That combination keeps the weight down while giving you a hard, corrosion-resistant surface that shrugs off handling, sweat, and the general abuse a working rifle sees. The flanged profile spreads the load where the base meets the rail, and it sits close enough to the handguard that it won't snag on gear or your hands.
Installing the Non-Rotating M-LOK Push Button Base
Everything you need to mount it comes in the package, including the hardware and an Allen key, so you can have it on the gun in a couple of minutes at the bench. One tip worth passing along from folks who've run it: a small dab of thread locker on the screws is cheap insurance against anything backing out under the stress of a sling being yanked, since GrovTec doesn't include any in the box.
It's a popular pick for AR-15s and PCC builds running M-LOK rails, and it works with standard GrovTec push-button swivels along with other common QD sling swivels. If you want your sling swivel to stay planted rather than rotate, this non-rotating base is the way to go.

Frequently Asked Questions
What does the non-rotating design on the GTSW193 do?
The non-rotating base keeps the swivel socket fixed in one position instead of letting it spin freely around its mount. That helps a two-point sling stay tidy and consistent against the rifle rather than flopping around. If you'd rather have the swivel rotate freely, GrovTec makes a full-rotation version under a separate part number.
Will this Flanged Push Button Base fit any M-LOK handguard?
Yes, it mounts to any standard M-LOK slot on an M-LOK compatible forearm or handguard, which covers most modern AR-15 and PCC rails. It works well on both rifle and pistol builds. You just need an open M-LOK slot where you want your sling point.
Does the M-LOK push button base come with everything I need to install it?
It does. The package includes the mounting hardware and an Allen key, so you can install it at the bench without extra tools. A lot of owners like to add a small dab of thread locker to keep the screws from backing out, since none is included.
What sling swivels work with the GTSW193 base?
The base accepts standard push-button QD sling swivels, including GrovTec's own push-button swivels. Most common QD-style swivels on the market will click right in. The swivel itself is sold separately from the base.
