Gletcher Grach-A Blow-Back

A little show of how the Gletcher-A blow-back is working. This one got to me with the sealing on the rear of the slide and the necessary blending piece on the back of the magazine. No effects added. The flashy shots are purely an optical effect due to the difference of the air-density and that of the CO2 medium. The Blow-Back action looks great but the kick is just a minor force and the barrel-spring is very soft.
