My advice would be get a decent regular rifle, and learn to use i
I agree, that makes sense.
But since it doesn't make any gorram sense to run around the woods pewing bits of plastic from toy guns to begin with, I went another way.
Well MB-03 @ £57
Spring, guide and piston upgrade kit @ £23 (the trigger and sear are already metal)
Plus a sighting solution.
Give that a try. You'll have the fps, and to spare: be prepared to cut the spring down, mine chronoed at
600fps with that kit in. But once you get it to 500fps, you'll be capable of slinging BBs as far as any other sniper, and then it'll come down to how heavy a BB you can hop, and how consistently you can hop it.
Then you can think about more upgrades.
6.03mm inner barrel @ £13. A
ZCI from ak2m4 would be better, if it were in stock.
Then on to the hop. The stock unit, well, it functions. You can throw in an Airsoft Pro aluminium arm, but you might have to shim it with tape, and file down the 'nub'. Or replace the unit with any of the aftermarket solutions.
In the meantime, get yourself a sidearm, and for that I'd suggest not a pistol, but an AEG carbine or SMG. The basic CYMA M4s work, and the CM.506 / 513 / 516 are shortish and lightish. Or one of the PDW or slidey/foldy stock MP5s, or a P90, all of which can be had for under or around £100. Heck, I'd suggest the JG Mac-10 if it didn't take those AEP batteries, but that could be rewired for lipos, or there are plug in lipo batteries becoming available.
Treat the sniper as an ongoing project. See how it works on each day. If it's not slaughtering your foes as you'd wish, switch to the AEG and you'll instantly be effective. Sling the sniper, or just prop it against a tree and get stuck in. Or use its scope for spotting, that's a useful activity in and of itself.
It's true that £200 spent on an AEG will be more effective, but if your heart is set on sniping, and you only have £200 in your budget, you
can get started. Just give yourself a viable backup option as well.
