Devgru Neo Posted April 23 Posted April 23 Hello there. I just wanted to kindly ask, I've noticed there are several airsofters that upgraded their cyma ebr into an electric blowback, I believe connecting a rope/string to the piston and the bolt. I couldn't find tutorials though. Could please anyone gently explain to me how to do it myself?
Supporters Lozart Posted April 23 Supporters Posted April 23 The only thing I can think of is that they've butchered a Tremors kit into the Cyma EBR Mod 1 that has an M4 buffer tube. Even then, it would need some work because it's not the same gearbox at all. https://www.modify-tech.co/products/tremors-2-recoil-system-for-m4-carbine-1 Also - EBR in this case stands for "Enhanced Battle Rifle" and is nothing to do with blowback or recoil.

Thank you good sir Yeah I know what an ebr means, I just wanted to replicate the sliding bolt, I'm studying a way to recreate the blowback as well, even though I'm no expert. Guess the easiest answer is a lvl 3 ra tech ebr

Devgru Neo Posted April 23 Author Posted April 23 I know ra tech is a gbbr, I meant to get a recoil action on a ebr. Never had the idea to swap gbbr internals within an aeg. Anyway thank you

Anyway thank you The gun in that video is just modified to have a moving bolt, not a blowback system. From what they describe, making the bolt move like that is relatively simple with a bit of engineering. To have an actual blowback effect (like an NGRS) you need an additional weight in the mix somewhere which is a whole other bit of engineering in itself, unless you find a way to transplant an NGRS/similar gearbox into your desired gun. No doubt it's possible, but probably not a DIY job either. Devgru Neo 1

I'm not quite sure I did Talking about just the blot slide They said they cut a slot in the gearbox and used string attached to the piston to link to the bolt. Personally, i would use solid (but sliding) linkage instead of string but as said before this isn't really DIY and is more engineering. Devgru Neo 1

Possibly, but it's more fabrication/engineering to do it well than typical teching. Probably needs some modification to the bolt too, and it may well impact reliability and eat gearboxes. The cost is another aspect to consider. If paying someone to do it you could get into hundreds pretty quick. Devgru Neo 1
