There are too many DIY mods to list them all on one post. I'll tell you a few here.

There is already a guide on almost every DIY mod you can do for fps here: http://airsoftsniperforum.com/showthread.php?t=4260

Then there is the guide on how to silence your rifle found here: http://airsoftsniperforum.com/showthread.php?t=1990

Then you can do the wax inner barrel spacer and the TDC mod (look in my sig for the link). That's all I can remember off hand.
