FX Impact o-ring help

[BillG]

I am wondering if the o-ring at either side of the port are the same for .22 and .25. For that matter, I'd like to know if there are any differences and what those differences are for all the calibers. The example that I have on hand is .22cal. they appear to be 10mm I.D.

I guess I'm a bit confused by the diagram on the FX website. In the drawing for barrel kit, A3 is 2 o-rings. They are 10mmx2mm. But on the B diagram, they are calling them out as caliber specific. Yet B3 is the same as A3. I'm wondering if the schematic is mislabeled. Anyway, I figured there are plenty of you out there that have had hands on experience with the platforms and could inform me of real world.

Same thing. Your talking about the brass part correct

The 'outside' of the brass port O-Rings are the same for .177, .22 and .25 calibers. The 'inside' of the brass port O-Rings are caliber specific. Attached is all items Impact, schematic, parts list and O-Ring sizes with order form TAB.
