  • Works As Expected

    I built my first .308 using an 80% DPMS Gen 1 lower and a “mil-spec” lower parts kit. When installing the magazine release mechanism I discovered that the threaded rod coming through the lower was so short that it barely engaged the threads in the included magazine release button. I was able to install it but with only a couple of threads engaged. It worked but the button barely cleared the side of the lower—making it difficult to push in fully when doing a mag release. (Virtually impossible when wearing insulated gloves.) I discovered this AP M5 extended button after doing some research and installed it. The button now protrudes out the side of the lower like it should and mag releases are much easier. Aero Precision does it again!

    Did a 5Dtactical billet .308 lower and threw a WMD nib-x kit on it but the release button would barely even thread on and was like a hiding turtle. Saw this and knew I needed it. Installed it and it is perfect for these type lowers and absolutely love Aero Precision. Just bought 3 more of these for other builds coming up. With the chaos of the election theft this week, I thank Wing Tactical for keeping these type of parts in stock as much as possible. Stay safe Patriots. Time is short.....
