Sling attachment guidance for the Beretta CX4 Storm. 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
Front sling swivel on the stock — factory attachment point.
Beretta's current CX4 Storm manual names a front sling swivel and states that swivels are mounted on the front and rear of the stock for the optional carrying sling. These are swivels already fitted to the carbine, not threaded studs or QD cups. The manual also notes that pushing the front sling swivel releases the under-barrel Picatinny rail.
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
Rear sling swivel and side slot-type swivel — factory attachment point.
The same manual names a rear sling swivel and a side sling swivel, describing the side one as a vertical slot type at the rear of the stock. The rear swivel is held by the stock spacer screw, so it comes loose when that screw is removed. Refit it carefully after changing spacers.
Factory attachment point: a webbing slot is not a QD cup or proof that a hook fits. Confirm the connector and webbing dimensions for this opening.

Why this sling on the Beretta CX4 Storm
A PCC is short and light, which makes it easy to carry badly — slung loose it swings into everything. Competition and home-defence use both want it locked flat to the body between stages, then instantly free.
The McLean design is a two-point sling with a patented retention system: it cinches tight to hold the carbine 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 carbine. 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 manual is Beretta's 2022 CX4 Storm user manual (UT007448/00). Earlier first-generation carbines were not checked against their own manuals and may differ in rails and fittings. Match your carbine to the manual supplied with it.
The factory swivels accept a sling strap directly, so a stud-mount or push-button swivel is not needed at these points. The side slot swivel suits a sling that is meant to lie flat against the carbine. Check the width of your strap against the slots before choosing a sling.
Questions
Does the McLean Dynamic Retention Sling (DRS) fit the Beretta CX4 Storm?
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 CX4 Storm?
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 CX4 Storm?
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: a webbing slot is not a QD cup or proof that a hook fits. Confirm the connector and webbing dimensions for this opening.
What length sling do I need for the Beretta CX4 Storm?
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.
