You can more than double the capacity of the Ruger Mini Thirty semi-automatic rifle with ProMag’s 50-round drum magazine.
With a body constructed from a proprietary nylon resin, a hybrid steel/polymer magazine tower and a heat-treated stainless-steel magazine spring, the drum weighs 1 lb., 14 ozs., empty and 3 lbs., 12 ozs., when filled with 7.62x39 mm cartridges.
Drum magazines can have a reputation for being unreliable, but the ProMag functioned perfectly well through three separate range trips.
The drum is far faster to empty than it is to fill, however; even once you understand the process for reloading it, expect it to take a good 5 minutes to load all 50 rounds.
MSRP is $130. For more information, visit promagindustries.com.
