    I have a new 392 (.22 cal.) that hits so far left that I run out of sight travel when I try to zero it. With the rear sight as far right as it will go, the gun still hits about 2.0" left at 10 meters.

    There was some paint in the bore at the muzzle which I cleaned out with acetone and a Q-tip. When the stock open sight would not zero, I installed the proper Williams 5D aperture sight, thinking it would give me more travel. It did but not enough. So far it only has about 30 shots through it, so it's not broken in.

    I have not cleaned the barrel as I'm a bit unsure of how to clean a brass barrel without damaging it. There appears to be no simple access for a cleaning rod from the breech and I fear damaging the barrel using a rod to clean from the muzzle. Also, I'm reluctant to use my .22 bore snake as it has some brass bristles in the brush portion. I fear these may also harm the bore.

    I'd like to avoid sending it back for warranty repair as the gun does group very well, just not where it's aimed. Does anyone have any suggestions? Is there anything I don't know about the 392 that would correct this?
    Thanks.

    Don't worry about cleaning the barrel. I got one I shot for 30years literally 5-10 thousand shots. Mine was a Benjamin Franklin and was used when I got it. Lead don't really stick to brass. If you feel like it need cleaning just shoot a felt cleaning pellet through it.

    I bought 2 new ones for my boys for Christmas a few years back. They are definitely not made as well as the old ones. I sent them back to Cabela's as one wouldn't hold air and they both mangled the pellets upon chambering.

    Call tech support or send it back. I'd like to know what they say.

    With that much of a POA/POI discrepancy at 10 meters, you should be able to see the problem with close examination.

    Something's bent or not lined up, or twisted to one side or perhaps there's a significant flaw in the barrel at the muzzle.

    Id suggest first taking a look at the front sight, make sure its properly aligned. Make sure the barrels exiting the sight block in the middle, qnd the sightblock is attached to the lowertube in the correct orientation. Next look down both sides of the barrel back to front whil facing a light source, see if theres any obvious bends....Now call crosman and inform them of any issues your having qnd of anything youve found while looking the gun over. Their customer service has been excelent in my experience, and should get you fixed up and back to shooting pretty quickly.
