I was wondering about the GT commando 2 paintball gun . It has 1 O ring through out the whole gun and there is ABSOLUTELY no plastic parts what so ever . I was wondering if anyone has this gun or now someone who does , are they worth buying or is there something better for the money ( $164 ) . It also comes with a sub zero expansion chamber ; are they any good . One more question ; what about the 16" dye barrels for the spyder . Are they worth buying ? Thanks for reading my retarded question .
