The only other gun I have used is a rental Tippman 98. Comparing anything to a rental is not fair, as the Tippman was well beat, but dependable. The Spitfire is a good gun, and has not left me stranded. Finding parts (o-rings mainly) has been "interesting".
Rhino Spitfire, 100%% stock.
Expansion chamber and higher grade o-rings than factory supplied units. I have experienced muzzle fog on cold days.
Very accurate, high rate of fire, and seldom chops balls - if you pay for good paint. The gun will know if you try to use cheap paint and will slice and dice until you sally up with the good stuff.
Chops cheap paint under rapid fire. The gun is touted to be field strip-able, but my experience says "not fully". Velocity adjustment is under designed and susceptible to damage when the utmost care is not taken. The adjuster should be a knurled knob with a lock, not an 1/8 inch allen socket in the center of a soft aluminum disk -
Excellent gun for the beginner and stealth fighters - beginners because it is simple and inexpensive - stealth because it is fairly quiet and deadly accurate out to range. I rate the gun overall a six because of the excellent quality and simplicity, not any higher because of the under designed velocity adjuster.
