5 To personalize the GraCoil recoil reduction system, bring the gun to your shoulder as if you are ready to call for a target. If the unit compresses when you perform this action, the compression of the unit is set too light. Remove the pad again according to Step 2 and increase the compression ONE TURN by inserting the 3⁄32" Allen wrench into the hole in the center shaft and turning the wrench counterclockwise (heavy) to increase compression. COMPRESSION ADJUSTMENTS ARE A MATTER OF TRIAL AND ERROR. Adjust ONE TURN at a time until the unit ceases to compress when brought to the shoulder. If the compression is set too light, there will be excess motion from the gun when shouldering, thus affecting accuracy. If the compression is set too heavy, more recoil will be felt. FIGURE 19 Insert Allen wrench here FIGURE 20 PROPER ADJUSTMENT OF THE GRACOIL SYSTEM IS ESSENTIAL. FAILURE TO PROPERLY ADJUST THE COMPRESSION COULD RESULT IN PERSONAL INJURY. IF THE TENSION IS SET TOO LIGHT, THE UNIT COULD COMPRESS ENOUGH TO PINCH THE SHOOTER, RESULTING IN INJURY. 6 Once the gun can be shouldered without compressing the GraCoil system, the system is properly set-up and will effectively absorb recoil without affecting accuracy. 7 Reinstall the butt plate by sliding it back into the stock and tighten the set screws using the 3⁄32" Allen wrench. Do not not to over tighten the set screws. 21
