Sling attachment guidance for the Mossberg 835 Ulti-Mag. Check your exact configuration and both connectors before choosing the McLean Shotgun Sling. Factory attachment points do not by themselves confirm a direct fit.
Front attachment
Magazine cap sling swivel stud — factory attachment point.
Mossberg’s release for the 835 Ulti-Mag Field pump lists a mag cap sling swivel stud as standard. The front attachment on that model is a stud on the magazine cap. It needs a stud-mount swivel and is not a QD socket.
Factory attachment point: a stud needs a compatible sling swivel to provide a loop. Confirm the swivel dimensions and attachment type; the sling hook does not attach directly to a bare stud.
Rear attachment
Rear sling swivel stud — factory attachment point.
The same release lists a rear sling swivel stud on the 835 Ulti-Mag Field. Mossberg’s optic-ready 835 turkey release also lists sling swivel studs. Confirm the buttstock stud on your own shotgun.
Factory attachment point: a stud needs a compatible sling swivel to provide a loop. Confirm the swivel dimensions and attachment type; the sling hook does not attach directly to a bare stud.
Why this sling on the Mossberg 835 Ulti-Mag
A hunting shotgun spends most of the day carried, not shouldered — across fields, in and out of a blind, over a boat gunwale. The sling needs to sit still while walking and come off fast when a bird flushes.
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. Unload and clear it following the firearm manufacturer’s instructions before fitting any accessories.
- Front: confirm a compatible connector and follow the sling and attachment manufacturer instructions.
- Rear: confirm the matching connector for your stock or rear attachment; do not assume a slot, stud and QD cup are interchangeable.
- 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.
Choosing hardware for your configuration
The cited Mossberg releases cover the 835 Ulti-Mag Field models and the optic-ready turkey model. Other 835 versions, including older combos and guns with replacement stocks, should be checked directly for the same two studs.
A replacement magazine cap may not carry a stud. If the cap on your shotgun is plain, the front attachment described here is not present. Check both ends and the swivels you already own before ordering.
Questions
Does the McLean Shotgun Sling fit the Mossberg 835 Ulti-Mag?
Compatibility depends on the exact configuration and connectors. Confirm both attachment points and the connector fit before ordering. A factory attachment point does not by itself confirm a direct fit for the McLean sling.
Do I need a snap hook for the front of my Mossberg 835 Ulti-Mag?
The McLean sling already carries a front hook. Choose a compatible attachment loop or swivel for that hook, and confirm its clearance and closure on your exact setup before buying additional hardware.
What do I need to buy for the Mossberg 835 Ulti-Mag?
Front: Factory attachment point: a stud needs a compatible sling swivel to provide a loop. Confirm the swivel dimensions and attachment type; the sling hook does not attach directly to a bare stud. Rear: Factory attachment point: a stud needs a compatible sling swivel to provide a loop. Confirm the swivel dimensions and attachment type; the sling hook does not attach directly to a bare stud.
What length sling do I need for the Mossberg 835 Ulti-Mag?
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.
