The BT-4 is in the same league as the Tippman 98c, and well it performs much like the same in my opinion. Ther marker has a tough shell, but because of this it is heavy. I really doubt you could break it however. Stock the marker in incredibly slow, and not overly accurate, but not horrible either. The marker is a good woodsball gun if your looking for something other than an A-5 or 98c, but its practically the same thing. My biggest gripe would have to be cleaning. Stripping, there is not field strip to begin with, and I find it annoying to clean paint out of the picatanny rail. It has an offset hopper, which allows for aiming down the barrel, which is nice for beginners but absolutly unnecassary for experienced players. An E-trigger and E-hopper would be a great upgrade for this marker to competetive. Also a longer, new barrel. If your getting into speedball just dont even bother though, its simply not worth it. Woodsball, its a decent gun, and has worked flawlessly everytime I have used it, even under demanding conditions. HPA would help its consistency a lot as well, but runs fine on CO2 no problems.
Its a tough reliable marker. Not recommended for speedball, would use for woodsball however, some ups make it a great marker. Decent marker stock as well.
