so I am new to autocockers and had a few questions about them. I want to upgrade my trigger and frame and am unsure to what will fit, I would like to go electronic if i can for a reasonable price, I am looking at the system x v2.0 frame don't know if i can use it on my marker. Plus I need suggestions for barrels
Yes, it will bolt right on to your marker. For barrels, a barrel kit is always best since autocockers are closed bolt, but if you don't want to spend the money on that, get a good inexpensive barrel such as the Proto 2-piece.
LPR requires an adapter to work I think (can't remember 100%). If you wanted to eventually get an eframe, that would require an adapter to mount it. TechT shaft kit is a great purchase if you plan on getting a different mechanical frame, as it will allow for retiming of the 3-way.
If you like the SystemX you mentioned earlier, get it. It's basically the same as the WGP hinge. For mechs, I consider all hinge frames to be identical, as I prefer slider frames.
