I have for your consideration a Evanix Rex 45cal carbine with fill probe, has a 16" barrel and a single point sling adapter. I got it in a trade last fall took it to the range once it shot great with good power but I didn't chrony it and it has being sitting in my gun cabinet and holding air ever since, nothing wrong just need to thin the herd a little. Asking Was $635 Now $595 OBO shipped I accept PP F&F or USPS Money order...Thanks Terry
