QRBP Repair Busta' way
Umm... yesterday i dropped the breech plug. It hit perfectly on the big round ; i thought all was good... but then it bounced, rotated, and hit on the thin rim, bounced, and hit on the rim again. What i was doing, was trying to avoid using a solvent to clean the plug, since i have been coughing because of some malady. A small piece of scotch brite pad was chucked in a drill motor, and holding the plug in one hand, and the motor in the other, i commenced. It didn't take long, and the plug took a trip from my fingers to the floor.
Not long ago Busta noticed a QRBP i had modified, was leaking around the end, and suggested i use a bolt to open up the rim, and refit it to the rifle. It was done, and it was an improvement. The bolt i used had a tiny bit of thread on the nose, so i put it to the grinder a tad.
Then the bolt and the plug were squoze some in the vice.
Then the plug had to be remarried to the rifle, but the fitment mortice was filled, so a pipe wrench was used.
Then for some assistance against leakage, i wrapped the end of the plug with one wrap of teflon tape.
The single wrap of tape didn't impede my abilitly to install, and remove the plug using just fingers. After 9 shots, here is what the plug looks like...
