Other than the above mentioned defect, the quality looked to be very good. I did call the manufacturer and they told me to simply return the product and they would send one correctly sized. I didn't want to wait or pay the postage, so I opted instead to carefully remove about 1/8" of the threads the extension is affixed to. With that the extension secured the barrel snugly to the action.
- How accurate was the sizing? Poor.
- Please tell us about the quality of the product. Good except for manufacturer defect.
- Was the product free of any manufacturer defects? This extension was too long to secure the shotgun barrel to the action.
I have an FN Herstal Tactical Police Shotgun. After some research, I found out that this shotgun is assembled on the same line as the Winchester 1300. Taking a chance, I ordered this extension for my gun. It fits and works perfect! The ultimate zombie killer!
