I use a rhino spitfire I just got it and I still haven't even wasted all the co2 out of my tank
Recommended Upgrades:
maybe a longer barrel but that's it:)
Strengths:
It is an awesome gun. It is really cheap for the price but you get alot out of it.The best gun I have used yet even my friends complimented me on it:)hehe.and my gun has a metal trigger and it works fine it doesn't jam or anything and I reall had only about 3 paintballs get chopped out of maybe 350 I mean wow that's great and you can pick it up at farm+fleet. and it's around 60$ to about 90$.This gun is really great on co2 and paint so go out and buy you a spitfire:)
Weaknesses:
The only thing is prolly sometimes the hopper gets kinda loose but you can always get a new hopper but you prolly dont even need a new hopper
Conclusion:
It's my favorite gun so go out and get one now cuz they are a good price and a good product.the only upgrade I recommend is maybe a longer barrel and a sight for it or a scope and then you will be all set see ya on the field
