Our unique popper base is made completely out of AR500 and offers 3 setting options all on the same base. You can use it as a forward fall, or add an extra bolt through the base to make it static for practice or long range shooting when you don't want to have to reset it. All this is done without having to use any tolls to switch positions unless you have to calibrate the rear fall, and you can switch plate sizes without tolls as well. We also have the only 2 plates in one base double popper base that is being used in matches all over the country. These bases are made to be mounted to a wooden base, but can be mounted to anything you want, we have even had guys just stake it down to the ground.
Double popper base are built to order only, and may take some time to make before they ship. Call for lead time or availability if time of deliver is a concern.
