Stiffer detents, and slotted bolt, definitely get a second pressure gage for the high pressure side, it will help in fine tuning and break-in.
How about FAST, LOOKS, Design, performance, JUST VERY SWEET
Requires regular maintenance (greasing various components)
This marker is awesome, here are my favorite things about this marker
1. It can keep a very high rate of fire without breaking balls.
2. The looks grab alot of attention, and will definitely get you some nice compliments on the field.
3. The trigger is very sweet with a quick short pull to ensure your rate of fire is fast.
4. It is very, very light.
5. It has a simple modular design, so you can make upgrades as you wish, and is pretty intuitive on how it works so you approach it with some confidence as you break it apart.
6. Service, the guys at BLAST are great, thanks Terry!
7. High quality construction and durable internal pneumatics (no external tubes all over the place just begging to get pulled/broken)
This marker sits atop of my list of markers out there. Its simple high performance design makes this marker pretty untouchable. If you want a marker that will give all the performance and has looks too, then definitely add this one to your short list for consideration. I PROMISE YOU WILL NOT BE SORRY!
