Shoot For Life with the ELMS PLUS Back Cap which allows you to upgrade your existing ELMS Laser Cartridge and get all of the benefits from our patent pending replaceable rubber strike pads. Each Back Cap comes with 5 additional rubber strike pads. This ELMS PLUS back cap will screw onto your existing ELMS cartridge body. When dimpling or wear begins to noticeably affect the laser firing, it’s time to replace or flip over your rubber strike pad. Simply grab the two protruding ears on the rubber strike pad and pull straight out to remove it from the back cap. Each rubber strike pad has 2 identical surface sides where your firing pin hits to engage the laser. This allows you to flip the strike pad over 180 degrees and reinsert the into the back cap or if you’ve already exhausted both sides of the pad, replace it altogether with a new strike pad.
