BERGARA MAGAZINE BMR 22WMR/17HMR 10RD

Description

The Bergara BMR magazine is a straightforward replacement or spare for BMR rimfire rifles chambered in either 22 WMR or 17 HMR, and its dual-caliber compatibility is the most practical thing about it. Rather than stocking separate magazines for two different cartridges, a shooter who runs both calibers through the same platform can use a single magazine format across both, which simplifies logistics at the range and in the field.

The single-stack configuration keeps the profile slim and the feed angle consistent, both of which matter for reliable feeding with rimfire cartridges that can be finicky in higher-capacity or wider-bodied designs. Ten rounds gives enough capacity for an extended varminting session or a full rimfire practice run without the bulk of a double-stack body that would alter the rifle’s handling characteristics.

Bergara produces this magazine specifically for the BMR, so the fit and retention are engineered to the rifle’s own tolerances rather than adapted from a donor design. That matters most at the point where the magazine locks into the action — a properly fitting OEM magazine seats fully, drops free cleanly, and doesn’t introduce play that can shift point of impact between reloads. For a precision rimfire platform used at distance, that consistency is worth more than it might appear on paper.

If you shoot both cartridges and already own a BMR, carrying a couple of these covers both calibers without any additional hardware investment beyond the barrel swap your rifle already accommodates.
