That depends on what you going do with it. woods ball or speed ball.
Flatline barrel, a regulator if using co2.
Strengths:
Everything. marker is just the best out there. made by tippman....
Weaknesses:
Not much. barrel is too short for some people.
Review:
This is the first marker i ever got. was in a package deal, hopper, tank and stuff. played with my friend's out in the woods here and it just smokes!!! took a 2 year break from playing and just started to get into it again. (have other marker's for play) very durable marker, hardly any maintenance on it. i just oil it up and go play. recently i was playing against a "pro" team here, and the the owner of the field came up to me after a few rounds and asked me what i got in it? i told him stock all stock, he was amazed!! the way this thing fires!! i got a good marker!
Conclusion:
Buy it!!! the best marker out there!!! easy to fix and use!!! this is now my main backup marker. but most players are scared of it. they say it hurts, poor baby's!!!
