Magnum Load Sure Cycle system for all Benelli shotguns with 21mm receiver threads - 12 and 20 gauge

The BNL-03-21 system has a much higher total spring load than the standard BNL-01 system. It is recommended for shotguns being used mostly for hunting applications. It requires at least a high velocity 1-1/8 ounce target load to properly function. It is designed to deliver maximum performance in hunting conditions where debris, cold temperatures and heavy payload shells require more energy to properly cycle

This system fit receivers with 21mm threads

To best determine the proper thread size of a Benelli shotgun is to remove the stock and inspect the factory tube

If the factory tube is steel, the threads are 19mm

If the factory tube is aluminum, the threads are 21mm
