Yes sir i to was very dissapointed to see mine. it all started with the constant diesling and then to diminished power and opened her up pulled out the piston and the seal looked like a rabbit was chewing on it and sham on me for not paying closier attention i justed ran the wet dry 320 paper down her to give it some lube holding texture and new seal, lube and back together. the rifle did shoot better and then began getting inconsistent then loss of power and i pulled the gun apart and with close attention to everything this time i shined the light down the tube and found my seal eating problem.i ran a cylinder hone down it and worked it over real good but could not remove the entire issue it was way to deep so i give up though i did get it together and is shooting good for now but for sure will be a problematic seal eating machine with regular shooting activity and i'm very sorry to hear someone else got the same gun with the same issue.
