Sling attachment guidance for the FN PS90. 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
PS90-specific front harness option — aftermarket attachment option.
Urban ERT offers a front harness made for the P90/PS90 body. This documents a platform-specific adapter option, not an integral AR-style QD cup. Confirm the adapter’s connection system and its compatibility with the sling you intend to use.
Aftermarket attachment option: confirm the connector fits and closes fully on the exact attachment. The existence of a loop does not establish McLean connector clearance.
Rear attachment
Stock-specific rear harness option — aftermarket attachment option.
Rear harnesses must match the stock configuration. Urban ERT separately lists a harness for a 2½-inch stock extension; that specialized part should not be assumed to fit an unextended PS90 stock.
Aftermarket attachment option: 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 FN PS90
Bullpup stocks place the action and magazine toward the rear. Check the strap route around that layout and use the documented attachment points to support comfortable, controlled carry.
The McLean design is a two-point sling with a patented retention system: it cinches tight to hold the bullpup 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 bullpup. 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
Before ordering a harness, identify any stock extension and whether the chosen front and rear adapters use proprietary buckles. A complete system from another maker is not evidence that its individual harness automatically connects to a McLean sling.
Use the PS90 owner’s manual to identify the firearm and keep the magazine, controls and access points clear. The PS90 and compact P90 are related platforms, but a photograph of one does not establish the exact configuration of the other.
Questions
Does the McLean Dynamic Retention Sling (DRS) fit the FN PS90?
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 FN PS90?
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 FN PS90?
Front: Aftermarket attachment option: confirm the connector fits and closes fully on the exact attachment. The existence of a loop does not establish McLean connector clearance. Rear: Aftermarket attachment option: 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 FN PS90?
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.
