Does the .177 LW Marauder barrel from Crosman use a different o ring than the OEM barrel?

No sir it does not. The o-ring size is based on the diameter of the bolt. 1.5mm x 4mm has been standard

Thanks for the reply. The groove for the o ring in the LW barrel I just received is about twice as wide as the one in the Crosman barrel and it moves when the bolt is closed causing the pellet to scrape against the lead. I'll call Crosman tomorrow.

If you have a caliper measure the cross section (thickness) of the o-ring and the I.D. (inner diameter). Is it possible an incorrectly sized ring is in there? Was gun bought new or used?

I bought the LW barrel from Crosman to replace the Crosman barrel in my .177 Field and target model. The o ring which fits snug in the Crosman barrel can move front to back in the LW barrel because the groove for it to seat in is wider front to back. If the same o ring is supposed to fit both barrels then the new barrel is defective.
