Got a carbine stock with sling slots but no way to run a modern push-button sling? The GrovTec Sling Tail Buttstock Base Adapter solves that. It feeds through your stock's existing sling slot and locks in place, giving you a proper QD socket on the other end so you can clip in a push-button sling swivel. No permanent modifications, no drilling, no trip to the gunsmith. It's the kind of small part that punches way above its size once you've got it on the gun.
The piece is built around a one-piece keeper base and a stamped steel keeper that works as a catch lock. That steel catch is what holds everything snug in the slot, and it's threaded through a tough 1-inch nylon web so installation is quick and tool-free. A rubber O-ring is thrown in to quiet down any click and keep the catch lock seated where it belongs. Owners routinely mention how tight and secure the fit feels once it's set in the slot.
This one is a favorite on M4 and CAR-15 style stocks, and folks running AR platforms lean on it constantly. A handy detail is that you can run the sling socket from either side, so lefties and righties both get a clean setup, and swapping it out takes under a minute. It plays nice with plenty of factory carbine stocks right out of the gate. Some Magpul stocks will take it too, though those may need a little extra fitting to seat properly, so plan for a bit of fiddling if that's your stock.
At roughly 3 inches of usable length with a black oxide finish, the Sling Tail is compact, low-profile, and built to disappear into your setup. If you've been wanting to ditch old-school sling loops for a quick-detach system without buying a whole new stock, this is about the easiest way to get there.
It's designed to fit many rifle stocks that have existing sling slots, and it's a go-to for M4 and CAR-15 style AR stocks. The tail feeds through the slot and locks in with the steel catch, so as long as your stock has a sling slot, you're in good shape. Fixed and factory carbine stocks with slots are the sweet spot for this one.
No tools, no drilling, and no permanent changes to your stock. You simply run the nylon web through the sling slot and let the steel catch lock hold it in place. Most people have it seated and ready to go in under a minute.
The included O-ring slips onto the catch lock to quiet any clicking and to help keep the catch seated securely in the slot. It's optional, but it adds a little extra peace of mind that the tail stays put under load. GrovTec also includes a spare catch lock mechanism in the package.
It will work with some Magpul stocks, but those often take a little extra fitting to seat properly compared to standard carbine stocks. If you're running a Magpul stock, expect to spend a couple extra minutes making it fit right. On plain M4-style stocks it usually drops in clean.
