This is my complete teardown of the Umarex Gauntlet in .22 caliber. While I tore the gun down I took photos and made some tweaks to help get more performance out of the rifle. I increased the barrel transfer port size, I polished the Hammer and Hammer tube, I chamfered all ports to assist in a better and less restricted flow of air to the back of the pellet.
