Description
Anyone who has run a QD sling on a fixed cup knows the frustration of a swivel that locks in at one angle and stays there. The GrovTec Flanged Push Button Base solves that with a full-rotating socket that spins freely once your push-button swivel is clicked in. That means your sling follows you as you transition between shooting positions, sling up on a hunt, or shift the rifle across your back. It threads onto any M-LOK handguard and gives you a clean, direct attachment point right where you want it.
What Sets the GrovTec M-LOK Push Button Base Apart
This base is precision CNC machined from solid aluminum and wears a Type-III hard anodized black finish, which is about as tough as anodizing gets for handling abrasion and corrosion. The flanged design seats the mount flush and adds stability, keeping everything aligned and rock solid under a loaded sling. It stays compact and low-profile, so it doesn't snag or add noticeable bulk to your forearm. GrovTec has been building this kind of hardware in the USA since 1987, and it carries a lifetime warranty.
Getting the Flanged Push Button Base Mounted
Installation is genuinely quick. The base ships with the hex screws and an Allen key you need, so you can pull it out of the package and have it on your rail in a couple of minutes without hunting through your toolbox. It accepts standard push-button QD swivels, making it an easy match for the sling setup you're already running.
If you want the freedom to move without your sling binding up, the full-rotating design is the big draw here. Folks who have swapped over tend to stick with these and keep a spare or two on hand. It's a small piece of kit that makes a real difference in how a rifle carries and handles.

Frequently Asked Questions
Does this GrovTec base work with any M-LOK handguard?
Yes, it's built to mount on standard M-LOK slots, so it fits M-LOK compatible handguards and forearms across most rifles. It attaches directly to the rail using the included hardware, giving you a QD sling point wherever you have an open M-LOK position.
What does full rotating mean on the flanged push button base?
Full rotating means the swivel socket spins a complete 360 degrees once your push-button swivel is locked in. This lets the sling move with you as you shift shooting positions or sling the rifle, instead of staying stuck at the angle it clicked in at. GrovTec also offers a non-rotating version if you prefer a fixed swivel.
Do I need any extra tools to install it?
No, the base comes with the hex screws and an Allen key needed for the job. Most people have it mounted in just a few minutes right out of the package.
Does this include the push button swivel itself?
This listing is for the flanged M-LOK base only, which accepts standard push-button QD swivels. If you don't already have a swivel, you'll want to add one to complete the sling attachment. GrovTec makes matching heavy duty push button swivels that pair right up with this base.
