Disclaimer Blocked Magazines

ASC magazines are designed and manufactured to a 10 Round capacity. In manufacturing the magazines to the specific capacity, there is slight room given to allow the magazine to be inserted on a closed bolt (the intended room is not enough for a full additional round), however any attempt to force rounds beyond the 10 Round capacity will render the magazine nonfunctional.
