Another howto video from Evike.com showing you how to replace and put in the CO2 cylinder into the APS CAP CO2 Pistol Magazine... "The Combat Adaptive Pistol or CAP is the CO2 powered sidearm offering from APS. The CAP features an ergonomically molded polymer frame, with lightly textured grip panels, providing a comfortable and effective non-slip grip.

At the business end of the frame is a 4-slot 20mm accessory rail, perfect for mounting weapon lights or lasers making it an effective weapon platform for both day or night operations.

The slide is constructed from a heavyweight metal alloy giving the CAP a hefty, realistic weight making it perfect for training and simulation. Front and rear serrations make weapon manipulation easy and milled channeling along the top of the slide keeps glare to a minimum and a stamped American flag gives you a sense of patriotism while dispensing plastic freedom out on the field."
