One of the better built STBBs! The barrel is from an Empire Mini, it has a Trinity clamping feedneck. I was able to get this to cycle good on liquid CO2 but was having trouble with HPA.
It will need some tweaking to get going. This item is in the category "Sporting Goods\Outdoor Sports\Paintball\Paintball Markers".
The seller is "krazypeg" and is located in this country: US. This item can be shipped to United States.
