This is the Butler Creek magazine speed loader for Ruger 10/22 magazines.
Designed to feed the Butler Creek Hot Lips and Steel Lips magazine it will also handle BX series Ruger magazines provided you go gently and don't force it.
Made from polycarbonate and polymer you tip in a box of 50 rounds, give it a shake to drop them into the hopper, then add your magazine and turn the handle. The hopper is removable for cleaning and if you need to clear a case.
