Sling attachment guidance for the Beretta A300 Ultima Patrol. 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

The barrel clamp carries integral M-LOK slots and a QD socket, and takes a QD attachment on either side.

View mount →Why this sling on the Beretta A300 Ultima Patrol
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. 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.
Questions
Does the McLean Shotgun Sling fit the Beretta A300 Ultima Patrol?
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 Beretta A300 Ultima Patrol?
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 Beretta A300 Ultima Patrol?
Front: Factory attachment point: a QD cup needs a matching swivel; a socket provision may also need a separate cup. Confirm what is installed and what the hardware includes. Rear: Factory attachment point: a QD cup needs a matching swivel; a socket provision may also need a separate cup. Confirm what is installed and what the hardware includes.
What length sling do I need for the Beretta A300 Ultima Patrol?
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.
