You can get a rail for the grip, if that's of any use for you.
Though he doesn't answer emails, so it'll be quite difficult to get one.

One of my other hobbies, fixing up the bus.
Incredibly awkward to work on, engine is right underneath the drivers seat so you have a limited work space.
Got it for free so I can't really complain.
Welcome to the forums!
1. Best to check here http://www.airsoftmap.net/Skirmish/
2. To put it simply: yes,
3. Not really, Marui guns have incredible range so you shouldn't have any issues. Ofcourse if you want more punch then get a slightly stronger spring.
Actually, there is. Perfect shimming and/or a good quality motor will make your aeg much quieter. I swapped out the standard motor from my Dboys KAC pdw for a Marui EG700 motor and it shoots a lot quieter.
Prepare to spend a lot on upgrades. Lol.
The best sniper platform you can go for is the Marui VSR, or any clone VSR.
If you don't like the look of them then the Well L96 is also a very good platform.
Other hobbies? Well, lets see..
Building stuff on 3DS Max, Photoshop (concept art), working on my car, was an avid animator a few years ago, RC flying, airsoft...
I've got too many hobbies, lol.
All their M4's and M14's. G&P M14's are super quiet and have incredible performance / rate of fire out of the box, their M4's are pretty standard internally but externally they're gorgeous.
The £50 Combat machine!
Replaced the inner barrel with a 500mm tight bore (Suppressor hides it) added a Madbull clear bucking + H nub, tightened up a few things here and there.
Has pretty good trigger response with an 8.4V Battery!
