My custom built recoil 416. The BRSS has some very decent recoil to it. Bolt has released a 416 recoil model but it is only available in Japan. I decided to make my own -I call it the Faux-16. I modified an old A&K 416 upper that I had laying around to fit my Bolt B4A1 and threw on an ICS 416 style stock. Bolt\'s rifles have decent parts in them to begin with so the only thing I did was swap out the motor for a Lonex A1.
