Tuning 7-spoke with o-ring for crown MKII CF barrel sleeve to shroud spacing

Hi guys I had some time this week finally and printed up some 7-spoke spacers with o-rings for the MKII CF barrel sleeve to shroud spacing. I offered these before a few years ago here but I'm running a small business and didn't have time to respond to requests for more over the months until yesterday.

The new rings look like this:

Installed with CF barrel sleeve it looks like this:

If you thought about using the CF barrel sleeve on the Crown MKII, you have to remove the factory installed spacers to install the CF barrel sleeve. Once the CF barrel sleeve is installed you can no longer use the factory spacers since the barrel outside diameter has been increased.

These may work on other FX Airguns if the shroud inner diameter is the same as the MKII and the CF sleeve has the same outside diameter--though I have not tested this. But if you buy the spacers and they don't work for your application you can request a refund. Return or proof of destruction of the spacers will be required, and refund doesn't include shipping.

Here are a couple of field reports on the spacers for airgunnation users (unrequested, uncompensated):

Look in classifieds for "FX Crown MKII spacers for CF Barrel Sleeve / Shroud in Yellow"

I cannot be sure I will have time to fill requests even next month...this is a hobby and I usually have way too much real work to do.

Feel free to respond with your testing in this thread (good/bad/indifferent).
