Just before posting the difficulties I am facing with my first ORION and the Nitro Piston here, I e-mailed Dr.Y.P.Shirsat stating my problems and received his reply yesterday. I don't know if it is proper to post a personal mail in an open forum. But I am posting it anyway since there is nothing sensitive in it and saves me a lot of typing on the keyboard to explain its contents. My last e-mail before the one I sent to the Doctor a few days ago was on 10-04-2013. This e-mail however proves that Precihole Sports do care for their customer's feedback and tries to help them. Here is the mail I received:

Dear Mr. Rao,
Thank you for supporting us.
As you know we faced QC issues in the beginning of our production. Gradually we worked to resolve these.
Actually the receivers are supposed to be passed after gauging. Possibly your first Orion was manufactured before this process was introduced. Later the geometry of the barrel to breech was also changed to have better uniformity to prevent excess barrel droop, hence the present production receiver assembly may not fit your earlier barrel assembly. What used to happen in the earlier batches was that the receiver would distort when the trigger box was welded due to excess current and thick wire used. This process has subsequently been refined and the problem sorted. Regarding your problem I would suggest you try polishing the rear end of the receiver tube with rough and then fine emery and see if the problem is solved. We can try to see if present production receiver will fit your barrel if you send it to us but it is unlikely to fit.
Regarding the Nitro unit I think the drop in power is not significant and attributable to burning off of excess lubricant. Do not remove the unit from the receiver tube but continue about 500 shots which is the real time it takes for a piston powered gun to really settle. If you face any problem we will replace the Nitro unit free of cost. The leakage of oil is normal in the first 200 to 250 shots so dont worry unless the power drops to unacceptable limit.
Once again thanks for writing to us and giving us valuable feedback.
Regards.
Dr. Y.P.Shirsat

So I decided to try polishing the Receiver tube to correct the distortion and see if it works. I pray to God that it works because a new current production receiver may not fit my old ORION's barrel. If polishing doesn't work then I'll send my guns action to their factory to see if the new receiver fits. If it doesn't fit then I'll try to convince myself that I never purchased my first ORION.
After trying to fix my first ORION , I intend to shoot at least 500 pellets from my NP ORION and see if it settles down as the Doctor advised. Hope everything works out okay.
