The BT TM-15™ is an excellent choice for any woodsball or mil-sim paintball enthusiast. Its high performance body is strong, yet light enough in weight for all-day action. Equipped with features usually found on much more expensive markers, the BT TM-15 features a true electropneumatic operating system as well as reduced sound signature for stealth firing in any of the multiple firing modes. With the standard multiple Picatinny rails, accessory options are nearly endless. Internal airline operation eliminates external hoses. Plus, front and rear sights ensure you get your shot.

The TM-15 was an impulse buy for me. It just felt right in my hands in the store, and presto, bought the gun.
My first day of play wasn't ideal, as the gun immediately had problems - when I gassed it up using a remote hose, it would expel a paintball from the breech (even when it was not on). Velocity was inconsistent at +/- 20 FPS.
Using the rip-clip was problematic because it would not pick up the sound of the gun firing (and this is the rip-clip for TM-15s and TM-7s, which should have the better microphone) - finally, it would break balls in the barrel - every 150 rounds or so.
Tried different barrels, including my Redz Pepper Sticks, no difference.
I removed the Rip Clip and put on the standard elbow with an Eggy 3 - same ball breakage problems in the barrel, but the loader had no problem keeping up with even the highest fire rate on the TM-15.
Because I had been warned about solenoid problems with the BT TM guns, I just replaced it with BT's "upgraded" solenoid. All problems solved immediately.
Gun is extremely quiet, shoots very straight (it just feels right, and seems easy to aim)
I replaced the plastic sights with adjustable metal sights - the plastic ones are non-adjustable, and are level, which means that even at close range, you can never see the ball flying as it drops below the sight picture as soon as you shoot.
Because the top rail is broken up by the feed port on top, it's hard to mount scopes and red dots behind the loader. Also, the loader gets in the way of the sight picture on sights - rip clip solves this, but see my comments on the problems I have had with the rip clip.
The selector switch is well placed, and the gun is fairly easy to program. I set the fire rate to the max for three-shot and full-auto and whee! Great fun. The rip clip has trouble keeping up with the max fire rate though - either because it can't hear the gun or because it's a max rate of fire issue. I suspect it's a problem with the microphone hearing the rapid rate of fire and thinking it's fewer shots because the sound runs together. I'm going to keep the rip clip in case I ever play in a scenario game where tac caps are required - otherwise, it's staying in the box. I have used and Eggy 3 and a Halo Too on the gun with no problems - well, the Eggy had to be mounted backwards because the breech is so far back on this gun.
The body is strong, but i'm pretty sure it doesn't require something like 15 screws to keep it together. Seems to have "rub" marks on it already on the spots that stick out.
The gun has Invert Mini pedigree, but since the solenoid is no longer in the pistol grip, there is no need to keep the distinctive Mini grip shape, and the $%?&* mini ASA/regulator. A standard 45 grip with a gas line inside would have been ok. As always, screwing a tank into the ASA is very diffcult even with lube on the threads.
The battery mag is neat. No more screws to get at the battery between game days! I'd like to see a shorter mag though - no need for that huge empty plastic thing under the gun. I also want another left and right shell, so I can cut it shorter. I think the gun would be very nice with the front shroud about 5 inches shorter.
Once the solenoid was replaced, the gun was marvellous. Not impressed with the rip clip or the sights. Not sure if a paintball marker costing over $500.00 should require additional purchases just to make it work - but BT, why on Earth would you sell an "upgraded" solenoid, AND ship guns with a known solenoid problem? How does one decide if it's time to upgrade to a "better" solenoid? When the stock solenoid turns out to be crap?
I'm giving this a 7 because no matter how great the gun is NOW, it was not functional out of the box. If someone replies to this and tells me that BT now ships the gun with a proper solenoid - I'll up the score by a couple of points.
