Sling for the Mossberg 590A1 | Fitment & Mounts

Yes — the McLean Shotgun Sling fits the Mossberg 590A1. The front of the sling carries its own hook, so up front it only needs a loop to clip onto — never a second hook.

Front attachment

Sling stud on the magazine tube cleanout knob — already on the gun.

Mossberg lists the 590A1 front sling stud as an OEM part, fitted at the magazine tube cleanout knob. Retrograde builds carry it as standard.

No extra hardware needed here. The sling’s own hook clips straight onto it.

Rear attachment

Sling swivel stud — already on the gun.

Stud in the synthetic stock. SGA-stocked guns take QD cups instead.

Why this sling on a Mossberg 590A1

Duty, home-defence and competition use put a shotgun on and off the shoulder constantly, often with a hand busy loading. Retention matters more here than raw comfort: the gun has to lock against the body and release without a second thought.

The McLean design is a two-point sling with a patented retention system: it cinches tight to hold the shotgun against your body hands-free, then releases into a ready position in one pull. It ships in one size and adjusts, so there is no length to choose.

Fitting it

Clear the shotgun. Tube unloaded, action open, chamber checked visually and physically.
Front: clip the sling hook to the sling stud on the magazine tube cleanout knob.
Rear: attach at the sling swivel stud.
Adjust wearing your kit. A setting dialled in without a vest comes up short once it is on.
Check the transition. It should shoulder without pulling tight across your chest.

Questions

Does the McLean Shotgun Sling fit a Mossberg 590A1?

Yes. At the front the sling uses its own hook, so it needs a loop to clip to: the sling stud on the magazine tube cleanout knob (already fitted). At the rear it attaches at the sling swivel stud (already fitted).

Do I need a snap hook for the front of my Mossberg 590A1?

No. The McLean sling carries its own hook at the front as part of the retention system. It only needs something to hook onto — a factory loop, a swivel, or any loop you add. Buying a second snap hook for the front is wasted money.

What do I need to buy for a Mossberg 590A1?

Nothing at the front — the sling stud on the magazine tube cleanout knob is already on the gun. At the rear the sling swivel stud is already there too.

What length sling do I need for a Mossberg 590A1?

There is no length to choose. The sling ships in one size and adjusts, so the same sling covers carry and cinched retention. Set it wearing the kit you actually carry in — a setting dialled in without a vest or heavy coat comes up short once it is on.
