Tuning kit for xs208(sysng)

[storer916 0]

I have the smk synsg which is part of the 208 range this is a good gun that i use often but i am wanting to add a tuning kit to make it a bit more smoother when firing. I have used it for both hunting and targets and can make clean kills and 1inch groups at 35yards. The main reson for the tuning kit is because i just want to make the gun a bit diffrent as i am getting into modding my guns (all above the law and always under the legal limit). i also have plans to shorten the barrel and add moderater for looks more than anything else.

Any way was just wondering the the best kit would be with out damaging the gun in the long run many thanks guys.

p.s i dont need to be told to spent money on better guns that are not chinese i have other guns including tx200hc and bsa scorpion and this one works just the same as they do with a bit more pratice.
