CJ, I gather you made one and found that it works well?
Phunkypants, as I explained you don't want to tighten it too much. Just a light pinch should do the trick or you'll just swell the Freak in the barrel and make the job more difficult. The green handle as shown is more than enough to be able to hand tighten the FIGG into the insert for enough pressure to pull it out. It is not needed or in any manner a good idea to tighten the screw with an allen key at all.
I had a "Paintball God" moment once.
Like Al Bundy's Polk High football moment I live on
for the slim chance of repeating that one time
miracle in some small way.........
