G&G armament cm16 srxl battleship grey

Here I have my favourite airsoft rifle, it is very reliable never had a single problem with it. I have had it upgraded with new springs and new high torque motor to make it more powerful, it was firing at around 315fps now it’s firing at 345- 350fps. I have also had a new core barrel put in to make it so much more accurate. And it has a max hop up chamber installed. All totalling around with the rifle £550. Comes with a magazine also see pictures. Any questions please don’t hesitate to ask
