Description
Getting a solid sling point on a carbine with a collapsible stock has always been a little fiddly, and the GrovTec Tri-Base Buffer Tube Sling Mount solves that without turning the job into a project. It's a two-piece clamp that wraps around a mil-spec buffer tube and drops three quick-detach sockets right where you need them. No punches, no springs flying across the bench, no pulling the stock off. You clamp it on with the included hardware and you're done.
The three QD receiver positions sit at roughly the 4, 6, and 8 o'clock spots on the underside of the tube, which gives you real flexibility depending on how you run your gun. Toss a swivel in the 6 o'clock socket for a straight-down two-point setup, or move it off to one side if you shoot with an offset carry or want a cleaner single-point feel. Each base rotates fully, so your sling can follow your body instead of fighting it.
What Makes the Tri-Base Mount Hold Up
GrovTec machined this from 6061-T6 aluminum and finished it with a Type III black hard-anodized coat, so it shrugs off holster wear, weather, and the general abuse a truck gun or range rifle sees. It's light enough that you won't notice the added weight, and the anodizing keeps it looking sharp instead of scuffing up your tube. The mount fits standard mil-spec tubes measuring about 1.14 inches in outside diameter.
Setting Up the GrovTec Buffer Tube Sling Mount
Installation is genuinely quick, and folks who have run one tend to mention getting it on in about a minute. GrovTec includes the Allen key and mounting screws in the box, and the recommended torque on the #8 screws is 20 to 25 inch-pounds. A dab of thread locker on the fasteners is smart insurance so nothing walks loose under recoil. Keep in mind this is the free-rotation version, so pair it with a QD push-button swivel that suits your sling and you've got a clean, dependable setup that carries a lifetime warranty from GrovTec.

Frequently Asked Questions
Do I have to take my stock off to install the Tri-Base sling mount?
No. The two-piece design clamps directly around the buffer tube, so there's no disassembly of the firearm required. You just fit the halves around the tube and snug down the included screws. Most people have it mounted in about a minute.
Does the GrovTec Tri-Base mount come with a QD sling swivel?
It does not include the swivel itself. The mount provides three QD receiver sockets, and you'll add your own push-button QD swivel to match your sling. GrovTec and plenty of other brands sell push-button swivels that drop right into these sockets.
What buffer tubes does this fit?
It's built for standard mil-spec buffer tubes with roughly a 1.14-inch outside diameter, which covers most AR-15 pattern carbines running a collapsible stock. It also works on other platforms that use a mil-spec tube, including some shotguns with adjustable stocks. Commercial-spec tubes have a slightly different diameter, so confirm you're running mil-spec before ordering.
Will the mount loosen up under recoil?
It holds well when installed correctly. GrovTec recommends torquing the #8 screws to 20 to 25 inch-pounds and never exceeding 30. Adding a little thread locker to the fasteners is a smart move to keep everything tight over the long haul.
