This came off a 6 Creedmoor. I ran it through the ultrasonic cleaner and the finish came so I threw some paint on it and haven't used it since. It has some pushed out corners I guess from removing it I don't how but there on it and it's price accordingly. I've knocked those edges off will a file before easily and repainted or polished or just leave them they don't hurt anything. These are $90 new and the work threads 5/8x24 $45 obo USPS money order or check
