I've used high-end semi-auto markers but nothing compares!
Blue Mayhem with a 2 piece Taso StoneCold BigBore Barrel, 120z c02, and an ACI drop forward reg.
Nitro or Compressed Air is a must, dont abuse this marker, a new barrel is never a bad idea, this is pretty much an all inclusive package.
Theres so much...lets begin:
-1.5mm trigger pull (extremely light as well)
-Ectronic timing never breaks a ball
-EXTREMELY air efficient
-QUIET as hell (and thats when you dry fire it with c02)
-Very sturdy to hold
-Easy to find barrels
-no side to side play (on the trigger)
-No bolt, spool valve
-Easy to maintain
-Only 3 moving Parts (including the trigger)
The only one thing I didnt like:
-Because this gun runs on such low pressure, it has to get rid of the extra pressure (assuming your regulator doesn't have a blow off valve) and each time the gun fires it shoots excess air out the back of the gun causing for a slight kick, but very tolerable.
This gun wants to shoot, every time you pull the trigger (and sometimes when you shake the gun!) it takes off, almost mocking you, not only does it shoot, but it doesnt it well, without breaking paint, using very small amounts of gas, and extremely accurately. This gun has been wronged, it is horrifically under-rated for it's price!
I bought this marker about 5 months ago and have been nothing but pleased. I've used alot of different electro markers and none compare in reliabilty. This gun never breaks, i've put sawdust down the barrel and its shot flawlessly. Its got three moving parts including the trigger, so you don't have to worry about it breaking, and it's silent as all hell. With a good Air tank, this gun owns. And the best thing about it, is that its cheap, meaning you don't need to be rich to buy it, it's not expensive at all.
