How to Fix Sliding Forward While Shooting With AR Stock

The AR variant of rifles is based on the military M-4 rifle that was introduced during the Vietnam War. This rifle operates on a gas system that cycles after each shot. When shooting with a standard AR stock, the recoil may push the rifle back and your cheek forward, making for uncomfortable follow-up shots. It's possible to install a cheek riser on the stock of most standard telescoping rifle stocks to help stabilize the shooting platform and prevent your cheek from slipping.

Instructions

    • 1

      Pull back the charging handle on the rifle to clear the chamber of any ammunition. Make sure the rifle is clear of ammunition before continuing.

    • 2

      Extend the AR stock as far back as possible by depressing the adjustment level on the inside of the stock.

    • 3

      Place the cheek riser over the top of the stock, making sure the flat portion of the cheek rest is facing your shooting side. If you are right-handed, for example, make sure the flat portion is facing the left of the stock.

    • 4

      Press down on the riser until it clicks into place. Pull back and forth on the riser to make sure it's firmly in place. Some models of cheek risers require the use of two set screws to secure the riser. In that case, place the riser over the stock, press down until it clicks into place and secure the screws on the bottom of the riser with an Allen wrench or screwdriver as needed.
