Daisy powerline 856 barrel liner+condor

I had an old worthless 177 pellet only daisy pumper laying around and thought to myself that I might be able to convert it for use on the condor so I went about dissassembling the poorly made gun daisy had put together come to find out the barrel liners in them have no air transfer port drilled in it and the od of the liner fits the af breech nicely with out modification I then found some lightweight metal tubing that would fit af bushings and mounted the liner inside with rubber tubing to get a nice fit and then Allen head set screws to hold it in place Over all the project is a success the liner will to my amazement Group cp hp7.9 into a nickel sized groups at 30yrd in my opinion it is a cheap effective way to get set up for 177
