The Stoeger M3K is similar in design to the popular M3000 models, but features several important upgrades. One of the most notable improvements is the extended magazine tube, giving the M3K a capacity of 10 plus one in the chamber and making it an excellent choice for 3-gun competitions. In addition, the M3K comes equipped with a custom, elongated carrier to make reloading fast and easy as well as an oversized anodized aluminum bolt release.
