Rate of Fire
Easy to Clean
this is my TM-15 review, 1 year in.
i got this marker Christmas 2009 for $450 Canadian. as the TM series rip clip wasn't released yet i picked up a Halo B hopper and its worked great since. in order to run this marker you need compressed air, you cant use CO2. also a remote is a very good idea as the stock gets in the way of the tank.
Quiet- the TM-15 is noticeably quieter then any other marker I've used. the barrel and its porting is contained inside the shroud and this muffles the sound of firing. a lot of times playing woodsball the other team never knew that i was even firing.
Easy to Clean- like all BT markers you can clamshell the TM-15. if you only want to grease the bolts etc all you need to do is unscrew two screws at the back, lift the stock up, then twist and slide the bolt/spring out.
Weight- the TM-15 is very light for a marker its size. the TM-15 weighs a little less then an MR3 and about half the weight of a tricked out A5 or BT-4.
Rate of fire- you can put the TM-15 anywhere up to 25bps in full auto. out of the box its something around 10bps. i have mine set to 10.5. this marker feels really good firing in full auto, the action of the bolt is really smooth. when firing.
Accurate- because the marker runs on low pressure (200psi) and compressed air the TM-15 is very consistent. i get very tight grouping with the stock barrel. the nice thing about the low pressure system is that you wont lose performance until your tank is completely empty.
Doesn't Chop- in a year of using this marker, mostly in full auto with the Halo B, i have not chopped a ball yet.
the only issue i have had with this gun have been with durability. when i first gassed this marker up, it didn't work. i took to the local shop, got it back a week later, turns out that it wasn't assembled right. this seems to me to be a 1 in a million chance of happening so i don't really hold it against the marker.
however recently i was playing at the local field and the TM was hit by a shot right about where the board is located. it wouldn't fire. turns out that the shot knocked a wire loose and the solenoid wouldn't cycle. this is the kind of stuff that doesn't happen to purely mechanical markers, however it is the trade off for improved performance.
the gun itself does feel very good though, and the magnesium body can take a beating. and no parts are at risk of breaking.
finally a really nice feature of the TM-15 are all the little features of the marker, the quick change battery in the magazine is awesome. the ball detents are very well designed, the quiet barrel etc. the only thing i don't like about the marker is the velocity adjuster. to change the velocity you slide a panel back which is fine, then you use an Allen key to rotate a knob inside the gun. it is a pain in the ass, and the Allen keys really tear up the knob inside the gun.
All in all this is very good marker. it performs exceptionally. has alot of nice design features built in, its super quiet, and looks awesome.
