I don’t know how I missed this for 6 months but someone built a Bullpup BRN-180.
You can find the original post here!
Does someone have an account on that forum? If so shoot him a message for me and send him here, we need to chat.
He used an electronic trigger with a solenoid to actuate the “regular” trigger.
He has since moved the battery to the rear of the gun.
After seeing this I want to do the same thing and it might just end up bringing my SA-80 airsoft conversion back from the dead.
Airsoft lower with the guts out of a BRN-180 upper.
