Bought the BT Delta a while ago, and just took it paintballing. Let me start right now by giving you all a warning about the gun. It may be small and insignificant for you, but it was a big deal for me...
The gun that is pictured on all the websites is NOT what you get in the box. I.E., there is NO functioning cocking knob, or removable magazine. Luckily I was able to get those components off of a display model which Canadian Paintball swapped out for me.
On to the gun itself, The gun is light, and it looks really quite good. It is balanced from front to back, and feels comfortable to hold. I was able to hit targets from quite a distance, although exact numbers are not known. Overall, It was enjoyable, and having used an APEX tipped barrel in the past, the BT Delta's stock barrel was quite a surprise because I managed to get quite a bit of range out of it.
The gun is a BT, so you know that It'll last years, even though it is made almost entirely of plastic.
Conclusion:
Good gun from what I can see so far. It hasn't let me down in testing, nor the first play-through. NOTE, that as I play more with the gun, this review will be updated as such.
Any questions or anything, feel free to leave a comment.
The new models no longer have the real charging handle or removable magazine. As cool as that is anyway, its also kind of pointless. That means you have two charging handles, one that doesnt function, that you need to clean out when a paintball breaks on it. The removable mag, why would you remove it? You dont reload from it, you can store anything it, so whats the point. But at the same time, it is cool to LOOK at, but not for function or play.
