*** A side note. The clamp system in this kit sees 100% of the shock associated with every round fired. It is of the utmost importance that the clamp be as tight as possible so as not to move backwards. Loctite and frequent checking of the clamps is recommended. If the clamp works loose, all of the energy is transferred to the pins and screws, which are not meant to see that level of shock. ***
