Feb. 19, 2006. We traveled to the PSP Texas Open Paintball tournament in Round Rock, TX.  In between competitions, we asked a volunteer to test the strength of our Muzzle Spiker, Barrel Blocking Safety Device. Meet Adam Ellis of Henderson, NV. After putting our Muzzle Spiker on a Tippman 98 barrel, we asked him and a friend to pull it off. In a tug of war style battle, they were unable to do so. So then We asked Adam to unload a complete hopper into the Muzzle Spiker. 200 rounds were fired and the Muzzle Spiker did not move an inch. Adam and his friends were very impressed.
