The fully licensed Umarex Beretta APX Red Dot Optics Ready made by KWA gets to be reviewed by Bruce of BB2K Airsoft... "Today we take a closer look at the Beretta APX RDO GBB Airsoft from KWA/Umarex. RDO means Red Dot Optics Ready and therefore mounting plates for Doctor, Trijicon and C-More are included in the scope of delivery. The APX is available in Black, Green & Tan. As with the original, the grip backs can be swapped (unfortunately only one size is included) and the APX has ambidextrous operation. You can find out how it performs in this video. Have fun."
