1 minute to install
I ordered 2 to replace the bullet button on 2 S&W MP15s. It took me less than a minute to install and it was a drop in. The product doesn't feel flimsy. I tested the release with a few of my magazines (Magpul and generics) and all worked like a charm. Don't forget to order a spring to go with this release. Your old bullet button spring won't work. Pros: direct drop in for my riffles with painless installation (screw/push/rotate) Minor Con: should have come with a spring (sold separately)
