I may have gotten hosed. I traded a black rifle I had for a sidestamp poly with a SEI scope mount. I was told it only had about 150 rounds thru it, after the trade I got home and was looking it over and pulled the flash hider off and dropped my M.E. gauge in it and it reads 2. depending on how I set it in the muzzle it reads below 2. I take this means way more then 150 rounds fired thru it?
