Cyma Platinum SR-25 6 metal 150 rd mid-cap magazines that I modified to fit correctly. 1 high-cap magazine Maxx Hop Chamber Prometheus Purple Bucking Prometheus Barrel Gate Titan Mosfet ASG Infinity Motor PTS Enhanced Polymer Grip Shooting around 1.4 joules. Sounds slightly screechy. True "quick change" spring. That's my favorite feature. The handguard is a bit wobbly. It works but it can be replaced if it bothers you. There's a screw missing from the back of the stock, but it still stays closed. The stickers should come off easily. There's a lot of good parts here, but it needs some tech love. Includes the original box. Retail: https://www.evike.com/products/20730/
