Howdy gang! So with impending ammunition shortages, I've been doing a lot of plinking with a .22. I've recently been looking at the GSG 44 Stermgewehr (chambered in .22 LR): It seems like a cute addition to the armory, but I'm actually curious if it's realistic to install a binary trigger in one of these? I've poking around on the internet, and it seems like most people are just buying binary triggers that match the specific firearm they're looking to put it in. My Questions: 1. Does this modification require any FFL stamps / special legal BS? I don't think it does from my reading, but I'd like to be sure (no I don't live in commie-fornia). 2. Is there a specific brand of binary trigger that would work well for this? Or am I out of luck and it isn't possible? Are there more general alternatives people have played with (such as a bumpfire triggers)? 3. Does anyone have any experience installing them? Would this require machining or equipment that I don't have (I'd have to take it to a smith?) 4. Do they result in increased jams? I feel like my military experience in armory would suggest the lack of a sear traditionally reserved for burst / rapid rates of fire could potentially result in shotty performance (pun intended). Any experience here? Even if I don't put one this particular weapon (I haven't bought it, I'm just thinking about it), does anyone like using a binary trigger at all? Hate it? General thoughts?
