The Switchview™ USA AICS P-mag Extensions increase the capacity of your magazines by four rounds. If you REALLY cram them in there, you can get five, but they’re designed to be a +4. They also do a great job of protecting the bottom of your mags when they get dropped.
Just like our Switchview™ levers, the AICS P-mag Extensions are cut out of 6160 T1 aluminum and hard anodized flat black (more colors coming soon). Another really cool feature on our magazine extensions is we’ve licensed the tool-less take-down system from TTI. This makes them super easy to disassemble for cleaning!
