When I bought this marker I was looking to replace my old A5 woodsball marker. I was looking for something a faster, more accurate and quiet but still sturdy and reliable. After some research I found out that the BT TM 15 is basically an Invert Mini with a robust shell and I purchased the TM 15 and have not regretted it.
I am very happy with this maker. It was pretty much ready to go out of the box. All I had to do was adjust the velocity. The marker is fast (11bps out of the box-can be set up to 20bps), pretty accurate and extremely quiet and built very sturdy. At first I was not very happy with the trigger. The out of box adjustment is very light but after adjusting the tension on it I have had no complaints with it since. I have shot several thousand rounds through it and have not had a break yet. But in case there is a break the internals are pretty easily accessible.
If I had to make a complaint it would be that this marker is a bit on the heavy side and it is big. However, it is very well balanced. It feels light and nimble. I even played some speed ball with it and to my surprise was able to keep up fairly well.
All in all I think this marker is an excellent woodsball marker. It truly has the speed and accuracy like a tournament marker but still is robust and has milsim looks.
Great woodsball/milsim marker! It combines the accuracy and speed of a tourney marker with the robustness of a woodsball/milsim marker.
