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".
Marker Setup:
Rhino Spitfire, 100%% stock.
Recommended Upgrades:
Expansion chamber and higher grade o-rings than factory supplied units. I have experienced muzzle fog on cold days.
Strengths:
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.
Weaknesses:
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 -
Conclusion:
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.
