T238 Speed loader GBB BB knocker / unloader

Hi! This model is for knocking off the last BB from GBBR mag so you wont break your nozzle. Usually ofc we will load right ammount, but sometimes you are loading partially used mags or there is wrong setting on bb ammount. This can be installed using original screws. Just dont over tight. Put mags feedlips next to a bumb and just pull and 1 bb will come off.
