Airsoft G&G SR25 GR25 Parts

thingiverse

Some parts I designed for a G&G GR25. The hopup spacer is used to correct the nozzle offset if you are using a regular m4 hopup unit. I also included a receiver tensioner that's designed to eliminate wobble between the upper and lower. It fits behind the gearbox and is held by the buffer tube screw. Lastly there's a bolt catch if yours is missing, and a simple cap to protect the muzzle.
