Well MB4411 upgraded hop up and spring , last time it was chrono'd shot 490 on 0.2s , I have only skirmished it twice myself but great rifle to get into a sniper role with, some slight orange marks by the looks of it it was originally orange but previous owner installed the upgrades and painted in a matte green, I think I have reflected the small issues fairly in the asking price, comes with 1 mag but can include the rifle bag and scope in for the asking price , any questions or offers drop me a message. Can post for postage costs.
