We modify OEM FN mags to be permanently blocked to 10 rounds from an original 20 round magazine. Our modification actually makes the magazine easier to open for cleaning than it was originally. We remove the ribs on the body of the magazine that were used to secure the base in place and convert the base to a locking peg system. This allows you to open and clean the magazine without the aid of a c clamp or special tool. In doing this our blocked magazine is considered permanent and does not require to be sealed because of the fact that an original base will no longer stay on without the block inside.
