Another M4A1 airsoft electric gun which features a blowback function is available at Airsoft Panda. Made by Accuracy Pneumatics Shooting (APS) this is a full metal AEG with complete markings. This is made in Hong Kong, and comes with a hi-capacity magazine. You can get this from Airsoft Panda for US$152, shipping costs not yet included. Notice the club-foot stock in the photo and we wonder if this is standard in all their packages.
