Sig Sauer MPX Magazine Safety Flag

This magazine safety is easier to manipulate and use than a standard chamber flag. It also does not enter the cone of the barrel where abrasion can occur. I developed this to ease the process of making the firearm safe during competitions or at the range. The safety locks in just like a normal magazine until it is released with the magazine release. I also have the top extended enough to make the block visible through the ejection port so others can see it is in place.
