Cute little gun. Pretty quiet. Very accurate. Parts list Action Army Zero trigger Novritsch cylinder assembly M130 spring cut down a bit Novritsch Hopup chamber Maple leaf autobot bucking Madbull 6.03 black python ll inner barrel Project gun I put together from scratch. Trigger itself retails for $100. Shoots right at 1j, but is capable of more with a spring change. The internals will definitely handle it. At the moment, the stock piston and guide is installed as I find them quieter at 1j, but I will include the novritsch piston and guide. The “iffy”. The receiver screw threads stripped, so it’s held in place with some duct tape. Doesn’t wobble or anything, securely in there, but you’d have to re-tap the hole if you want to take the tape off. In the meantime, I put camo fabric tape over the duct tape. The other screws are all intact, however. The hopup is adjusted with a nut inside the chamber sticking through the outer barrel. It takes advantage of a groove in the novritsch chamber, making it like a sliding tdc mod. Stays in place, and is protected by the scope from accidental bumping. Worth noting though. Suppressor is not included. If you pay the asking price the scope is included. I know it’s a bit of a chop-shop gun in the age of the ssg10/tac41, so I’m selling it cheap. Just need to free space.
