Bleiz39 talks about an old workhorse, the Jing Gong MP5A3 RIS AEG which is hard to find these days. The MP5 has a metal gearbox for maximum durability and a polymer lightweight body. It features an A3 adjustable stock, battery wired to handguard (small tamiya), and ~350 FPS with .20 BB. The flashider has 14mm- threads and the gun has full auto and semi-auto firing modes. The package includes the MP5, a metal 240rd high-cap magazine, manual, and a black MP5 flash hider muzzle to cover the orange.
