Bought the SP-1, which is a Vibe in tactical bodywork. Out of the box, it performed flawlessly. Suppose to get into it's first game today (lost my hopper?!). But just outside practising, it's a great marker. A good rate of fire, adjustable trigger pull, LIGHT, efficient... what's not to like about it?
What would I change? Not much! A faster fire rate would be nice ($100 option by changing the board). Color body skins would be nice for Vibes (SP1 could use a camo body
). Not sure if the Vibe barrel is longer than the SP1 (10" for SP1) but I just added a 16 and experienced improved accuracy. That's just personal choice.
Problems? Only one. I hooked up the tank and heard an internal air leak. 2 Allen keys and <1 minute later the bolt was out. Wiped it clean and re-oiled it, back in and ready to go in less than 2. No leaks. So far I've put about 700 rounds through it and am extremely satisfied with the gun.
