Description
Getting a sling onto a Mossberg 500 shouldn't mean guessing at hardware or fighting a mount that won't sit straight. GrovTec built this set specifically for the 500, pairing a custom machine screw fore-end base with a rear wood screw stud so you get proper attachment points front and back. The whole kit runs on 1-inch loops, so it works with just about any standard sling you already own.
What Comes in the GrovTec Mossberg 500 Swivel Set
Inside the package you get the machine screw fore-end base, a .75-inch rear wood screw swivel stud, a spacer, and a matched pair of GT Locking Swivels. Everything is steel and wears a black oxide finish that keeps glare down and shrugs off corrosion. The front base is designed to work with the existing Mossberg 500 mag cap setup, and the rear stud threads into the buttstock for a solid anchor. Some light gunsmithing is part of the deal, so plan on a drill for the buttstock hole if yours isn't already drilled.
Why the GrovTec GTSW31 Holds Up
GrovTec has a reputation among gunsmiths and hunters for building swivels to tight tolerances, and it shows here. The close machining keeps the fit snug and quiet, which matters when you're moving through the woods or waiting on a bird. The locking design means the swivels won't pop loose when you don't want them to, and GrovTec rates its standard 1-inch locking swivels to hold up to 300 pounds of tension. That's more than enough backbone for a loaded 500 slung across your shoulder all day.
These are made in the USA, and folks who've run them describe a fit and finish that reads like factory Mossberg parts. If you want a sling setup that disappears until you need it, this is a straightforward, no-drama way to get there.

Frequently Asked Questions
Will this GrovTec swivel set fit my Mossberg 500?
Yes, this GTSW31 set is purpose-built for the Mossberg 500, with a custom machine screw fore-end base that works with the existing mag cap. It also fits many tube magazine lever-action rifles and carbines that use a fore-end band. If you're running a Maverick 88, folks report it fits and installs the same way.
Does installing the Mossberg 500 swivel set require gunsmithing?
Some light gunsmithing is involved. The front base swaps in around the mag cap area, while the rear wood screw stud threads into the buttstock, so you'll likely need to drill a small pilot hole in the stock if it isn't already drilled. It's a job most handy owners can knock out at the bench with basic tools.
What size sling works with these swivels?
The GT Locking Swivels use 1-inch loops, which is the most common sling width out there. That means the vast majority of standard 1-inch slings will thread right on with no adapters needed.
How strong are the GrovTec locking swivels?
GrovTec pull-tests its standard 1-inch locking swivels to hold up to 300 pounds of tension. The all-steel construction and locking design keep everything secure, so a fully loaded Mossberg 500 slung on your shoulder is well within their comfort zone.
