UPGRADE

I think I am going to use my ECHO 1 G36C as my main weapon so I would like to make some upgrades to it. I was hoping that some of you guys could give me some ideas on what parts and brands to get, and also what each part will upgrade since I am not sure what all the parts will do. For example a different spring will give me higher FPS. I was planning on spending around $100 or so. I would like it to be a little more accurate and have a little more FPS ( not a lot, I think its shooting around 350-370 right now ) I think it already has metal bushings, metal spring guide and has an M110 spring installed. I am totaly new to this so any help would be great.

Thanks

for accuracy and a boost in FPS I'd get a system M120 spring (not the M120s there is a difference) and a madbull 6.03 tightbore barrel 247mm length for the G36C.

So there is a difference between the System M120 and any other brand M120? Also I have been looking for an M80 spring to put in my JG MP5 so I can use it for CQB but the closest thing I have been able to find is a Systema M85. Will that work or do I need to find an M80, and if so do you know where I can find one?

Thanks for your help

Indeed there is a difference between the spring brands. I bought an ICS M120 and it put me up to 450 which I wasn't expecting.

the M85 spring will put you under 300.
