The ATI Bulldog M20BD10 10-round .410 shotgun magazine is a high-capacity feeding solution built for shooters who run .410 bore pump and semi-auto shotguns. If you're running a modern .410 platform and want reliable mag capacity beyond standard options, this steel magazine delivers the round count you need without compromise. ATI engineered the Bulldog line specifically for .410 shooters who demand dependable feed performance in the field or on the range.
Built from steel and finished in black, the Bulldog magazine is made to handle the rigors of active shooting. The 10-round capacity means fewer reloads during extended shooting sessions—a real advantage whether you're running drills, hunting upland game, or working through a clay course. It's designed to feed reliably with standard .410 ammunition, and the straightforward design means straightforward maintenance.
ATI Outdoors built a reputation on filling gaps in the accessories market, and this magazine is no exception. If your .410 shotgun is compatible with this platform, the Bulldog gives you genuine round-count advantage that most factory magazines can't match. Drop it in, load it up, and get back to shooting.
