Not really a super-duper customised M4 gas blowback airsoft rifle. But nevertheless if you prefer a King Arms M4 Gas Blowback rifle that has been fitted with Magpul PTS MOE furniture, then you can get this at War 4 Toys International for US$355. This has a power of 400-450fps on top gas, which means you have to use some other gas to lower its power for game sites that require 328-350fps.
