These are no new to the sport. However, the various one that I purchased just didnt fit or operate as one would prefer. The entire body from top to bottom are based upon several rifles with AICS mag wells, and also based on the build/measurement criteria of the AICS standard.

At the rear of the magazine, the catch has been widened and extended, below the the catch slot youll see a indentation for the spring latch to rest inside ensuring tighter and more reliable fit.

My intent was to make this fit more solid and securly instead of the sloppy ones that often get hung inside the well when trying to remove. This one atleast in my Bergara HMR Pros's and MDT chasis fit like a glove, and will eject like a normal fitting magaine.
