Hi, I was just running my .177 compact veteran over the chrony and a thin oring seems to have ejected from the barrel / shroud. I experienced no change in velocity or sound. Does this oring look familiar to anyone?
Tuning Veteran o-ring identification help, please

Looking at the 2nd picture your pellet diameter is d_pellet = ~52px. The inside diameter of the o-ring is d_broken_o_ring = ~123px, and the angle of the missing section is a_broken_o_ring = ~55 degrees. To find a replacement you need to determine the inside diameter of unbroken o-ring, so let's assume nothing is missing and the broken o-ring is a perfect circle:
d_o_ring = (360 - a_broken_o_ring) / 360 * d_broken_o_ring =>
d_o_ring = (360 - 55) / 360 * (4.5mm / 52px) = 9.02 mm
The d_cross-section = ~13px = 1.23 mm
You are looking for an o-ring ~9.02mm x ~1.23mm. Taipan Veteran .25 O-Rings has a list of o-ring and the only thing that comes close is "9.25 x 1.78. -012. pressure gauge". Grab a vernier caliper and double check the measurements of your o-ring.

awesome detective work and helpful oring list. I'll bust out the calipers and confirm the size / purpose. THanks for the help!
