I just got back into paintball after about 6-8 years of not playing. I had to upgrade from my pump wgp sniper and my MegaZ. I went with the War Machine Assault 80 after shooting one at a friends house. My brother who also just got back into paintball got one too. I bought mine used with every possible upgrade except the overdrive chip for $255 plus shipping on eBay. Paid $258.00 plus shipping for my brothers, brand new. If you can't find one on eBay check out
www.paintballadrenaline.com. (They said they could sell me another one for $269.99).
I definitely do not regret buying this gun. I am able to easily keep up with guys using matrixes, angels, and shockers. Mine needed a few minor adjustments, but my brothers shot great right out of the box.
The Assault uses cocker barrels (which is great since it interchanges with my sniper). I'm using a high pressure setup. The 05 reg keeps things nice and consistant. I'm not sure how many rounds I get from my tank, but its definitely up there. I'm working on setting it up with my warp feed like the 2nd video on their site. As soon as the eyes are done, they will be my next upgrade. Any questions, feel free to email me. About 6 or 7 people I play regularly with are using these guns.
