Overall this is a great milsim marker for the scenario player. In fact, it is one of the better markers out there. Straight out of the box, I doubt if there could be more satisfaction in firing a milsim- low kick which means placing the paint on your target and better grouping. It's rate of fire via the factory settings was impressive and low and behold this marker is very stingy with air.
I the past I have used primarily A5's and SP8's- both of which hog air. With basic modifications, the best I could ever get was around 1200 rounds with a 45/68. The TM 7 allows you to shoot close to 2100 rounds with the same bottle. This is a significant difference.
The stock barrel is not bad- but not great either. I would invest in an upgrade here, but for the average player, this barrel is sufficient for scenario play. The trigger assembly feels a bit too "plastic" and lethargic. There is no snap to it at all and I can see this being a problem in months to come.
Teardown is a bit intimidating your first time in. A lot of parts to disassemble for a complete teardown and a bit overly complicated. I understand that the performance is driven by the design intent- and the intent was never to perform a complete teardown. I will say however that there are small features that really make this marker a pleasure to own. Changing the battery can be done in seconds- even with gloves on.
It's been a long time since I've picked up a marker out of the box, fired it, and grinned. This is what the TM 7 does for the psyche. Are there features that need improvement? What marker doesn't. Lightwieght, good feel, easy on air, reasonably accurate out of the box, switch selection on the fly, field battery change with ease- what more can you ask for? Again, probably the best "out of the box" milsim marker on the market today.
