Hello. Im fairly new to airsoft sniping, but not to airsoft. Ive gone out and played almost every weekend for 2 years now and recently made a really bad decision. I compulsively bought a Mauser Pro Tac... Well in a phrase, its a complete POS. So I then read some good reviews about the KJW M700 and the only real problems people pointed out was the inconsistency in FPS due to temp of gas, and stock inner barrel. People also said the inner barrel isnt like a tanaka, so I was wondering if someone could make a list of immediate neccesary upgrades that fit the M700 without any modding. Thanks
