new barrel as the stock one leaves something to be desired
ease of use
Havent found any yet
OK, i took this outta the box and i was amazed! the milling isnt too extravagent but its nice and sets u apart from the other timmys. After playing with my trigger for a bit i got my *ss over to my friends house to use his air cuz i was out but i couldnt wait to air this up. After i shot it i think i sh*t myself because combined with the weight, speed, and accuracy i was amazed and forgot about all the cash i dropped on this so get off ur couch and get this gun!
