This Sig Sauer Magazine is a Factory Original Replacement Part, manufactured to the same specifications and tolerances using the same materials as the OEM Magazine that came with the rifle, guaranteeing optimal fit and reliable operation. When it comes to semi-automatic firearms, the ammunition feeding device often determines if, and how well, the gun functions. Therefore, whether for use as a backup mag for your home defense long gun, or simply to spend a little more time shooting and a little less time reloading on the next trip to the range, keeping a few spare factory magazines handy is never a bad idea.
This 10-Round AR-15 Magazine is the same as those shipped with each new Sig M400, 516 or 556 Series rifle that's delivered to a location with a law that restricts magazine capacity. This magazine is also an excellent choice for use in the prone position due to its small footprint beneath the rifle that allows both the gun and the shooter to get lower to the ground for increased stability.
