Promag
The ProMag 50-round drum magazine for FN SCAR 17 in .308 Winchester gives you serious capacity for extended shooting sessions at the range or in the field. Built from a proprietary DuPont Zytel polymer composite, this drum is engineered to handle the power of .308 Winchester while keeping your rifle topped up through long strings of fire. If you're running an FN SCAR 17 and want a high-capacity option that goes beyond standard box mags, this polymer drum delivers the round count without the weight penalty of steel.
ProMag's design blends modern polymer injection molding with proven metal components where it counts. The magazine upper tower includes a full-length steel internal insert—stamped and welded the same way factory magazines are made—to ensure reliable feed and durability under hard use. The follower is molded for consistent spring tension, and the magazine spring itself is heat-treated stainless steel, so corrosion and fatigue aren't concerns even if you leave it loaded for extended periods.
This is a USA-made magazine backed by a lifetime guarantee against manufacturer's defects. Whether you're zeroing a new load, running competitions, or just want faster reloads during a long day at the range, the 50-round capacity keeps you in the fight longer and cuts down on magazine changes.
