Description
If you have picked up a Luth-AR MBA stock, you already know it comes with molded pockets ready for a quick detach sling swivel, but nothing installed. That is where the GT-SL comes in. This is the GrovTec Heavy Duty Push Button Quick Detach Sling Swivel that Luth-AR points customers toward when it is time to actually attach a sling to that stock. It is a simple part, but it is the piece that turns a sling ready stock into a sling equipped rifle.
Why the GT-SL Pairs So Well with Luth-AR Stocks
Luth-AR designed the recessed cups on their MBA-1 through MBA-5 buttstocks around GrovTec hardware, so fit is not a guessing game here. The swivel drops into place and gives you a secure, low profile attachment point without adding bulk to the back of your rifle. It is the same setup Luth-AR uses on their own builds, so you know it was matched to the stock rather than just being a generic add on.
Push Button Quick Detach That Actually Holds Up
The swivel loop is sized for slings between 1 and 1 1/4 inch wide, which covers the vast majority of two point and single point slings on the market. GrovTec builds these with tight tolerances and pull tests them well past 450 pounds of tension, so you are not sacrificing strength for the convenience of quick detach. The push button release is smooth and fast, letting you drop or swap slings in seconds without wrestling with the swivel.
One More Thing Before You Order
This listing covers the swivel itself only. The threaded cup insert that goes into the stock and the installation tool used to seat it are sold separately, so if your stock does not already have a cup installed you will want to grab one along with this. Once everything is in place, this little swivel is one of those parts you stop thinking about because it just works every time you sling up.

Frequently Asked Questions
Does the Luth-AR GT-SL GrovTec sling swivel come with the mounting cup?
No, this listing is for the swivel itself only. The threaded cup insert that seats into your Luth-AR stock, along with the installation tool used to install it, are sold as separate items.
Which Luth-AR stocks will this sling swivel work with?
The GT-SL is built to fit the recessed cup pockets found on the Luth-AR MBA-1, MBA-2, MBA-3, MBA-4, and MBA-5 modular buttstocks. If your stock already has a GrovTec cup installed, this swivel should drop right in.
What width sling does the GT-SL swivel accept?
This swivel is sized for slings between 1 inch and 1 1/4 inch wide, which covers most standard two point and single point tactical slings. Double check your sling's width before ordering if you are running something unusually narrow or wide.
How many swivels do I need for a two point sling setup?
This is sold as a single swivel, so you will typically need two, one for the front attachment point and one for the rear, unless you are only replacing one side. Many Luth-AR stock owners order a couple at once so both ends match.
