Sling attachment guidance for the Swiss K31. Check your exact configuration and both connectors before choosing the McLean Dynamic Retention Sling (DRS). Factory attachment points do not by themselves confirm a direct fit.
Front attachment
Sling loop on the lower band — factory attachment point.
The Swiss Army technical regulation for the carbine states that the sling loop on the lower band serves to attach the carrying sling. It is a fixed loop on the band, not a stud or a QD socket. Check that the band and its loop are present on your rifle.
Factory attachment point: confirm the connector fits and closes fully on the exact attachment. The existence of a loop does not establish McLean connector clearance.
Rear attachment
Sling bar on the side of the butt — factory attachment point.
The same regulation names a sling bar set into the side of the butt as the rear attachment. It is a fixed bar on the side of the stock, so the sling lies along the side of the rifle. It is not a swivel and it will not accept a push-button QD swivel.
Factory attachment point: confirm the connector fits and closes fully on the exact attachment. The existence of a loop does not establish McLean connector clearance.
Why this sling on the Swiss K31
Lever-action and traditional rifle stocks can have fitted swivels, bare studs or no sling base. Establish the correct attachments first, then choose a carry setup that remains comfortable while walking and keeps excess strap controlled.
The McLean design is a two-point sling with a patented retention system: it cinches tight to hold the rifle 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 rifle. 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 regulation covers the K11 and the K31 together and describes the same sling fittings for both. It also records that the issue sling carries a snap hook so that it can be released quickly. That hook belongs to the sling, not to the rifle.
A strap or hook has to fit under the side bar and through the band loop. The regulation does not give the size of either opening. Measure both on the actual rifle before choosing a connector, and check a replacement or sporterized stock for its own hardware.
Questions
Does the McLean Dynamic Retention Sling (DRS) fit the Swiss K31?
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 Swiss K31?
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 Swiss K31?
Front: Factory attachment point: confirm the connector fits and closes fully on the exact attachment. The existence of a loop does not establish McLean connector clearance. Rear: Factory attachment point: confirm the connector fits and closes fully on the exact attachment. The existence of a loop does not establish McLean connector clearance.
What length sling do I need for the Swiss K31?
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.
