Save your fingers and magazines! Simply attach the LULA on top of any AR-15/M-16 .223 magazine and easily load AND unload loose rounds. When we saw it in action we knew that we had to have them! Simply click it onto the mag and work the lever back and forth. It's really that easy! It's lightweight (1.3 oz.) and pocket size, and has only two parts. Fits all .223 magazines including but not limited to: Thermold, Beta, Orlite, Colt, G.I. etc. Already in use by the Israeli Military and under evaluation to add to the U.S. Military SOPMOD kit. "Purchased one at BRC...Wonderful accessory/works great! Will be ordering more for my shooting partners soon." Bravo 5-2 Jon Kenneth, The I.S. Group Inc.
