i have used an avalon gt commando 3 and a Pirahna STS 2k3 G-force
right now, i am still using the avalon GT commando 2 because it shoots so straight and it is so nice when you shoot it.
i would upgrade from the stock barrel to maybe a 21"barrel that may be $30 and it works much much better with mine.
this gun shoots straight, and hard ive never had a better 1
the stock barrel
i have paintballed for 7 years, and thsi is 1 of the best, cheapest gun i have used. i would reccomend using this gun because it shoots so nice and accurate. you can upgrade many parts on this gun too, it is one of the best guns i have used, i have had it for 2 years, and it almost never chops a ball.
i would deffinitley reccomend buying this product because of how good it is for the price.
