We ran the announcement from GrovTec for their new Tri-Base buffer tube sling mount for AR-15 rifles back in February. It’s basically a clamp with three quick detach cups that fits on your mil spec buffer tube.
The selling points here are 1) it’s fully ambidextrous, 2) it’s made in the US and, best of all, 3) it doesn’t require you to disassemble your AR-15 to install a sling mount. It’s perfect for those of us who prefer a single point sling and don’t want to mess with replacing the lower’s end plate or hassling with a staked castle nut.
I loved the idea, so I got one.
Only one problem. I forgot that my AR has a commercial buffer tube. If you’re not familiar, that means it has a slightly larger diameter than a mil spec buffer tube. It also meant I couldn’t use my new sling mount.
Lucky for me, I hadn’t returned the Brace Built Modern Carbine yet that JWT had recently reviewed. It has a mil spec buffer tube, so at least I could give the Tri-Base mount a try.
Installation took approximately 30 seconds. GrovTec includes a hex key with the mount so you won’t even have to open up your tool box.
I didn’t install the mount on this gun permanently, but if you’re doing that, you’ll want to use a drop of Blue Loctite on each screw. The fit was snug and perfect.
The TriBase mount gives you three QD cups to choose from when mounting your sling.
I also got a GrovTec Single Point Bungee sling. While mounting it in the center works . . .
A left side mount works better. At least for me. With three mounting options, both lefties and righties will find a position that works for them.
MSRP is $47, but I’ve seen them online for as low as $30. It’s a quick, easy way to add a flexible sling mount option to your AR platform rifle and it definitely doesn’t suck.
