Both of you are correct. If the gun is permanently modified to shoot semi-auto only, then an M130 or M140 or equivalent would be field legal with a 50 foot minimum engagement distance. Of course, that rules you out of CQB, but that's sort of a no brainer.
Alright thanks. I just received my g&p 8mm gearbox, so ill be using that for a field gun and then ill have my dmr, no cqb for me. How exactly do you go about making the gun semiauto, and is it reversible? If I want to change back.
It will still go in to safe, don't worry. And no, it's not exactly reversible, but that's sort of the point. The gun needs to be modified so that there's nothing you can do at the field to make it shoot full auto. If it was a simple switch, nothing would stop people from chronoing with it modded to semi-only and then swapping it back in the parking lot.
You can get a second selector plate for about $10-$15 and leave it unmodified. They're time consuming to swap out, since you have to take the gearbox apart to do it. But it will allow you to essentially "reverse" the modification in the future.
Do you have to go inside the gearbox to actually make it semi only?(not an airsoft tech). Or is it possible without opening? Because I am not to fond of opening my gearbox. And I know of zero airsoft stores near Livonia/westland that I could have someone do for me(if you know some please enlighten me)
I've never done it, so this is purely a guess and somebody who has done it should correct me if I'm wrong. But I would think that if you're really careful with your dremel, you could get it done without taking apart the gearbox. You'd run the risk of blowing plastic dust into your gearbox, and that's of course bad for the gears and electrical contacts. You'd also run the risk of slipping and grinding away something that shouldn't be ground. But if you used a soft enough tip on your dremel, you could minimize any damage you did.
