Tuning Impact MKII barrel liner o-rings stuck

I was swapping out my barrel in my .25 Impact & when I removed the liner from the barrel sleeve the 3 0-rings stayed inside. I shook the gun but only one came out. A little air from my 135 PSI shop compressor didn't work because I couldn't get a direct shot into the sleeve from the breech. I finally decided to use my Patchworm cleaning kit from the breech with the .243 - .284 cal (black) cleaning head and a .25 cal. one of Patchworms felt buttons. I pulled the weed eater "cleaning rod" through & out they came.
