Detent rings are nice to have. Other than that it's all preference and comfort.
Strengths:
Light, small profile, as accurate as any good marker.
Weaknesses:
None. It's stock class, not a semi so ROF is not a weakness!
Review:
Took this out for it's first go the other day. She worked beautifully! So nice and small, agile and shot beautifully! I need to get a bit more used to the pump action and making sure to pump back fully, but that is me and not the marker. Excellent 12gram efficiency.
Cleaning was easy and swapping bodies and gas source is fast and easy in the thumbscrew/modular design.
I'll put some more in after using it out a bit longer.
Conclusion:
If you want to try Stock Class or pump, then this is the marker for you. So many customizable pieces to set it up exactly how you want. Don't expect to be able to go out and conquer all the semi players out there. Against the newest electros the Phantom is outgunned and requires different tactics but you can still be competitive. But it can be very fun and rewarding to take out an electro toter with one well placed shot!
