I was watching Tears of the Sun a few weeks ago and have been wanting to really build a Suppressed M4 sniper for Airsoft ever since!
Reference:
I have this little anti-rotation link that replaces the body pin that aligns the gearbox in the body:
It requires another body pin in the gun to keep it secure, so I made these larger fake pins for that (near the mag catch):
Installed:
Cut the outer barrel in front of the gas block, I will be using a relatively long Airsoft Silencer for this and I don't want it 5 feet long:
Here I am cutting it down to size to thread it for 14X1.0mm CCW threads:
The new threads:
Upper Receiver coming together:
I will be shooting allot of chrono shots to set this up correctly so I made this to make things easier:
It will let me screw the chrono right on to the Airsoft gun:
Next I will get into this:
