Since 1919, Mossberg® has been the leader in introducing important design breakthroughs to the firearm industry. Many product features pioneered by Mossberg® are now the standards by which all modern firearms are judged. Never content with the status quo, our men and women constantly strive to improve and update the capabilities of all Mossberg® products. In accomplishing this goal, we recognize that each improvement is a part of the “Shooting System” approach and most are designed to fit the shotgun you bought years ago.
