I have used a tippman 98,a couple of spyder markers that are similar in looks, automag, and a autococker markers.
I currently use two bruizer pro markers. I have 12" and 10" taso power barrels, 8" and 10" taso splash barrels, and a 8.5" taso ss barrel. Also I have a Brass eagle laser sight.
LAPCO Auto cocker to VM-68 barrel adaptor..... allows you to fit any autococker barrel on VM-68 and old bruizer paintball guns.
Three years ago I recieved a Bruizer Pro marker. At the time Nuline Bruizer pros were a unknown gun, so I took it to the local range to show it off. Alot of people were very impressed at how the gun performed overall. I have played against almost every type of gun on the market and this bruizer pro has held its own agoins extremely expensive guns like the Automag, Autococker, and many competion grade guns. This gun is a great entry level gun and I have to dissagree with an earlier review and give it some competion potential. If you study technique and learn and apply new stratagies you will find that this gun can be used to dominate any setup. Seal usage for the DURA-VALVE valve sytem on the gun is extremely mimimal(my first seal replacement on both of my guns for the valve system was after 3 years of use). Versitile and underated is my positive comment!
Stock barrel sucks and it is hard to find the Vm-68 threaded barrels for the gun. LAPCO has now came out with a Vm-68 to Autococker barrel adapter. This fixed the only problem I have everseen with the gun's compatibility issues.......for only 14.99 to 25.99$!!!!!!!!
If you buy a barrel adapter, learn technique, and buy a good after market barrel ,you will be able to perform as well and any semi-automatic gun on the market. Use a midgrade to high grade paint and it will pull you out of the toughest situations!
