What do ya'll think of this, it seems like someone may have been in here before or injected grease? I am not done with the tune yet... so thought I might get others opinions to see if this is normal for gamo shadow extreme. My intent is cylinder hone, maccari spring seal, de burr etc.... :) I am attempting my first full tune on this gun because it has been so inaccuate I figure nothing to lose and lots to gain including making a spring compressor!
