SNIPER Upgrade parts
Usually, the rear of the receiver is a separate section that is held on with a grub screw. This relies heavily on the trigger group bridging the underside to support the two pieces and stop any wobble. However, one trigger screw coming loose can cause a lot of issues so Action Army to the rescue!
