hi all
im thinking about getting a TM vsr-10 and upgrading it my self,

first off, does any one know of a web site that shows manuals and instructions for taking apart the vsr 10 and how to install a new spring, etc?
ive had a lot of experiance upgrading AEG's but never single action guns.

second, im wanting to buy the gun and the upgade parts on a budget. so what is the bare minimum needed to upgrade the gun to shoot at 500 fps.

third, if any one can talk me through the process involved in changing the spring etc, as ive heard you have to drill into the cylinder to remove the spring? ive tried searching for guides to upgrading the vsr-10 but ive had no luck,

hope some one can help
Cheers
