Usage Recommendations:
- As with all firearms, this Semi-Auto shotgun upper must go through a break-in period. In some cases, two boxes might be required.
- These uppers were designed and tested using European-manufactured 410 shotgun shells.
- For best results, use shells that measure 2.25" - 2.39" in overall length.
- Use .410 High Brass Shotgun shells to break in. A minimum of 1200 fps is recommended. These magazines will not accommodate all 2 1/2″ 410 gauge shells. 410 ammunition varies in length by manufacturer. If the shell will go into the magazine without forcing it the magazine will feed fine.
- We recommend the following brands for this upper: Nobel Sport, Herter, and Estate .410 ammunition.
