MAGS LLC EFX-A1 Enhanced Fixed AR-15 Stock is a replacement for your A1 or A2 fixed stock. The cheek weld has a correctly angled comb to align your head with the sights. The club foot shape is lighter and less bulky than the full A1 stock. The length of pull is only 13.375 inches to ensure a quick shot, even while wearing thick winter clothing. The rubber butt pad keeps the gun shouldered throughout any barrage of fire. There are two sling slots that can accept military nylon slings up to 1.25 inches wide. There are also slots for QD slings on either side. The large underside compartment will hold the spare parts you need in the field.
