Viking Tactics LPSM
Low Profile Sling Mount (LPSM) - my favorite sling mount. Presents a lower profile on your weapon so the sling mount doesn't get in the way when the sling isn't attached. Attaches to the top rail of the Extreme Battlerail eliminating the need for additional rails to be attached. The LPSM is compatible with all Picatinny rails. The VTAC LPSM is designed to make the Heavy Duty Quick Detach (HQD) Swivel lock in and limit the rotation, which feels much more secure to me by eliminating swivel rotation during movement. HQD sold separately.
