    As advertised

    This product was easy to install and does as advertised. The extended magazine is 1.5 inches longer than the barrel, but it doesn't look too bad. If you want to even it out or make the barrel longer than the magazine, install an extended choke. That's what I did.

    Great magazine extension and it matches the Marine. Easy to install. It does stick out a little past the barrel. I added a longer choke and it evens out. I love MAC, great firearms
