I have read all the stickied topics above. I have read the Bolt-Action forum. This is not a request for help to become a super l33t sniper. Not at all, I have been recently toying with the idea of getting a decent sniper rifle and upgrading it every now and then as a side project. I have an AEG and I am planning to buy another one soon. While playing recently at a event I volunteered to be a spotter with one of the experienced snipers. I seriously enjoyed that style of game, most we did was relay information and the only two shots that the guy took were both hits. It was alot of fun. So i thought I could slowly start building a rifle and over time not only will I have built something nice and accurate I will also have throughly learned to be a Designated Marksman and I will also have improved my Marksman skills.
Now my question here is what Kind of gun should I use as my base and what upgrades would be vital to improving it drastically.
I was looking at the Well G-22 because It works with my Bundeswehr Loadout. But I am open to ideas, like i said I am planning to re haul the internals so I am more or less just looking at the externals. I know well is the biggest piece of shit you can get. I know the whole you have to spend a lot of money story, I know that and I am willing to, just over time. I am willing to buy the best parts that I can find (given their price is realistic). Also Gas vs Spring what is superior in your guys opinion. I am more leaning towards spring because of its versatility in the winter and it has more reliability.
I am sorry for asking the old sniper question but I feel that I have realized the risks that come with it.
Edit-The TM L96 sounds sexy.

This is the G-22 it is a L96 with a folding stock (Wikipedia says so, I highly doubt that I think it is a retractable stock.) and a few upgrades. In real steel this one shoots a .300 Winchester.
