I got a Panzer clone off of ebay. I am not sure who made it as it did not come in a box; just bubble wrapped. I assume it was one of the cheaper clone companies. The issue I am having is with some atty's making contact. My Russian 91% and Oragin clone have no issues. However my Omega Clone will not make contact. I can't figure out if the pin in the Panzer is adjustable. Is it just not going to work with some atty's? The two it works with seem to be a tight fit when I get to the last 1/32 of an inch before the top cap and the Omega screws all the way down without issue.
