Mag Msbrg Mc1sc 7rd Clear Extended

The Mossberg MC1sc 7-round clear extended magazine is a factory-original component built to the same exacting standards as the equipment shipped with your firearm. Constructed from clear polymer, this magazine delivers transparent round-count visibility, allowing shooters to monitor ammunition status at a glance without removing the magazine from the pouch or firearm. The extended capacity design provides additional grip real estate and handling surface, improving control during malfunction drills and tactical reloads.

Designed for 9mm ammunition, this magazine maintains precise dimensional tolerances that ensure reliable feeding and extraction across a variety of ammunition types and configurations. The clear polymer construction withstands the thermal cycling and environmental exposure typical of duty carry and range training, while the robust witness holes provide accurate round-count confirmation in low-light conditions. Factory Mossberg production means feed lips and spring geometry match your firearm's magazine well dimensions exactly, eliminating the break-in variability sometimes encountered with aftermarket alternatives.

This magazine is ideal for shooters running the MC1sc platform who need backup magazines for duty rotation, range qualifications, or personal protection. The 7-round capacity suits concealed-carry applications where magazine count is secondary to ergonomic performance. Law enforcement and civilian operators who rely on consistent, mission-critical equipment will find factory Mossberg magazines the appropriate baseline for their ammunition supply strategy.

Original-equipment magazines remain the standard for precision-manufactured firearms. Aftermarket alternatives may offer lower cost, but factory components eliminate compatibility risks and service delays. Operators serious about reliability source spare magazines directly from the manufacturer.
