Bolt O-Rings

[slivershooter]

Does anyone know the size of the bolt O-rings on the 1317 and 1322?  I know I can get them for less than those considered a Crosman part. I  used to work parts at a John Deere dealership and O-rings were very inexpensive.

003 = .177
006 = .22/.20

yes you can get them considerably cheaper than crosman has them
iirc -004 .177
-005 .22
iirc
i'll check around if i am wrong i will post the correct sizes

The orings are close enough that 003 and 004 can work for the .177 and 005 and 006 can work for the .20 and .22
I believe OEM's are 003 and 006....have all 4 sizes and use the best fit for the way the barrel fits the breech and the geometry of the leade
also depends a little on the duro...I like the softer orings for the bolt

yeah! i can say that a -006 has been too big for my guns with .22 crosman barrels. it is the only .22 barrel i have tried with crosmans bolt and just about all the others
the qc is so poor at crosman anything is possible
tim of mac-1 says -003 for .177 and -004 for .22
