gas sniper rifle

lately I've been thinking , i want a gas powered sniper rifle.
i've been looking for one and i've found the m700 by kjw and I wanted to know who has a gas power rifle or spring rifle for that matter. and I wanted to what your opinions are about said rifles.

personally, gas powered sniper-rifles are a waste, in that they require much more maintenence, cost more, and aren't as unique/custimizable. My spring riflle (a basic UTG M324S) has lasted me a bit already. IMO, you should get a spring powered rifle, but if you really want a gas powered rifle, look for either Ares or UTG. They have really nice, long lasting rifles.

*edit* UTG dosen't have GAS sniper rifles. My bad, lol.

i've had spring rifles before and there not realistic, plus every spring rifle ive had from the vsr10 to the echo1 m28 slam fire. you don't get that from a gas rifle

hm then idk man. I've never fired a kjw before. but like any other gun you buy, just do as much research as you can on these things and make a smart decision
