Madbull M576 O-Rings.

[siggypoo]

I've been trying to find replacement O-Rings for Madbull's M576 Slugshot. Specifically part 07, the Front Valve O-Ring, but have had no success. Two orders over a period of seven months from Hero's, and I get every O-Ring but the one I need. I understand it's somewhat difficult with a no-longer produced nade, but the parts have to be out there somewhere.
If I can't get original Madbull, might there be a non-airsoft place I could order from that'd have an O-Ring that'd do the job?

Common sense is so rare it should be a super power.

If you know the size of the ring there are alot of options. I work with fire extinguishers. There are as many diffetent sized rings as u could imagine. Most used to hold back nitrogen but some for co2 and halon gases as well (even the nitrogen ones should be quality enough for propane and even co2 at airsoft pressures.

Take a measurement (inside or outside diameter, and thickness) and look for O-ring places or ebay.
The Madbull orginal O-ring is just a horribly overpriced O-ring anyway.
For the material of the O-ring, propane or CO2 or a little silicon oil is not really harsh to O-rings, common material like Nitrile should work just fine, no need to go expensive like Viton. It is not like you are putting strong solvent or corrosive liquid or high pressure in there...
Since you don't have the orginal O-ring, try to find someone else with same item and take a measurement. Or in the worst case, take a measurement of the O-ring groove.
