Basic questions dealing with the Valves and Mechanics of CO2 Revolvers

[TheAzn]

1. Based on the CO2 revolvers I've looked at, they all utilize flimsy materials (brass/aluminum valves, copper tubes, tiny CO2 puncture-pins, etc.). Yes, I am probably exaggerating since such materials and designs would not be ubiquitous if they are too weak; however, my experience with these materials has definitely left me wary of any future CO2 gun purchases. Are there any C02 replicas with more sturdy valves and tubes than the revolver pictured below?


2. What has been YOUR most reliable CO2 revolver? How often do you change the seals and clean with pell gun oil - and how often do you use the gun?

3. Do any of you happen to have a YouTube video on how to most-correctly take apart and reseal the standard valves and tubes?

It's been a very long time since I've had a co2 revolver, but brass and aluminum are standard valve materials in many, if not most, pneumatic air arms (including paintball markers). Some days I'd put 4-8k cycles on a paint gun, and they all held up fine. Air revolvers tho use smaller, often more complicated, and sensitive parts and transfer tubes. Co2 sans expansion chamber or regulator, is rough on seals as well.
Personally, when i had a co2 revolver, a Crosman 1357, I shot one or two co2 caps a day. The little magazines wore out before the seals failed, but they eventually did as one would expect. I didn't try resealing them at the time tho, as I figured I'd just buy another. Still haven't after my last one 10years ago.

I've got a couple co2 revolvers that have held up for 3-4 years so far. I've never taken them apart and I don't leave co2 cartridges in when I store it and keep the seals oiled. They're so inexpensive I wouldn't bother trying to resuscitate them when they die.
