Sling attachment guidance for the AR-10 / .308. 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
M-LOK slot in the handguard — aftermarket attachment option.
Large-frame ARs use the same M-LOK handguards as the AR-15, so the front sling point is added rather than factory. Weight is the reason to care where it goes: further back balances a heavy .308 better on the carry.
Aftermarket attachment option: a webbing slot is not a QD cup or proof that a hook fits. Confirm the connector and webbing dimensions for this opening.

Stock QD socket or receiver end plate — not confirmed for every configuration.
Most large-frame stocks carry a QD socket; where yours does not, a QD end plate behind the lower does the same job.
Attachment details are not confirmed for every configuration. Check the exact model and manufacturer documentation before buying hardware.
Why this sling on the AR-10 / .308
A .308 AR is heavy enough that the sling stops being a convenience. Carried muzzle-down over a day it pulls on the shoulder, and a loose loop swings hard when you crouch or climb. Locking the rifle to the body is what makes the weight manageable.
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.
Questions
Does the McLean Dynamic Retention Sling (DRS) fit the AR-10 / .308?
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 AR-10 / .308?
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 AR-10 / .308?
Front: Aftermarket attachment option: a webbing slot is not a QD cup or proof that a hook fits. Confirm the connector and webbing dimensions for this opening. Rear: Attachment details are not confirmed for every configuration. Check the exact model and manufacturer documentation before buying hardware.
What length sling do I need for the AR-10 / .308?
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.
