Well, found a bunch of these, more than I can use. These are correct, mil-spec black Viton O-Rings for upgrading your extraction force. They have excellent chemical resistance, and temp resistance of -20 to 400 degrees F. Asking $3 per 4 rings shipped USPS First class. Additional rings are $1 per 2. Preferred payment is cash, as money orders are something like $.70, so unless you are getting a bunch, it does not make sense. NO PP *EVER* UNTIL THEY DROP THE Anti-2A BS. I can add delivery confirmation and insurance at your expense and discretion. Please post in the thread the quantity you would like, followed by an email or IM. Thanks!
