If you have purchased a Shotgun or a Paintball Compact, you can use the Brass Swap Kit to easily convert your collector over to be able to pick up pistol and rifle brass. The brass swap-out kit can convert your Compact so that it can pick up 9mm, 10mm, 40, 45 Auto, 38 Special, 357 SIG, .308 (7.62mm), .223 (5.56mm), and much more. The Ammo-Up will pick up all rifle and pistol brass with the exception of the .22 rimfire. Ideal surfaces are concrete, carpet, dirt, sand, and grass up to 4-inches long. Detailed instructions included.
