Title: Crosman MKII - Switching Barrels from .177 to .22 caliber
Post by: Cybergrizzly on February 16, 2012, 03:02:47 AM
I read somewhere that you can easily replace the .177 caliber barrel of the MKII with a .22 caliber MKI barrel.  Understanding that a new .22 bolt pin will also need to be replaced.   Quesiton is...that's it ? 

Are the front and rear barrel nuts the same ?   Rear bolt knob fits right into the .22 caliber bolt pin ?

No more issues or things to know ?

Thanks

if you have a .22 bolt then the .177 barrel can be prepped to use that .22 bolt --- kinda hard to go the other way though,might be possible,maybe  ??? .the only thing different is the bolt and o ring that would  pose a problem between the two (.177 and .22) barrels

As said...I would change both, the barrel and the bolt to .22 caliber.   There should be any issues to my knowledge.

Front and rear barrel nuts are the same for both calibers.  The bolt knob will work with either the .22 or .177 bolt.  Only the barrels, bolt, and bolt seal are different.
