Was looking for a realiable marker that was highly upgradable and came across the bt-4. A friend had one and was highly impressed by it.
The first thing you need to know is you will need to drop about $50 right off for a new barrel as the stock one is 8" long and not all that accurate.
Secondly, the gun is a tank and can really take a beating. I haven't had too many issues with it other then a small air leak in the braided hose fitting and a hex nut that stripped.
The gun is made by Ben Tippmann so you know it's quality. If you are more than a beginner I would suggest buying one of the already upgraded versions of the marker like the assulat, swat or Ironhorse.
