Fantastic, Reliable, Game changer.
These extensions are absolutely fantastic. I put about 1000 rounds through them and I am so impressed.  These will be fantastic for my EDC.  I will forever be a Shield Arms customer. Thanks guys for this innovative and reliable product!

Worth It
I'm going to be honest.  I waited a while to get a  5 Extension for one of my S15 magazines because I thought the price was high.  But now that I have one in hand, I can see why!  This is not a flimsy stick on but is instead engineered to become a part of the magazine.  I've never been a big fan of mag extensions because they're usually a thin plastic snap on.  Not here!  This thing is a high quality metal with a fantastic finish.  It mounts with set screws and is rock solid.  Best feature?  For cleaning the magazine, all you have to do is take the set screw out of the base plate.  You do not have to remove the extension to clean out the mag internals.  My opinion on the selling price now is that it's extremely reasonable for what you're getting.
