556 Single Mag Insert w/ MP2

I was a little worried the MP2 wouldn't hold a standard mag snugly, but the fit is spot-on with zero wobble. Even with the chest rig cinched down, the insert keeps everything locked in place during a run and gun.

Fits my standard mags snugly inside the micro rig without any wobble, and the MP2 insert holds them secure even when I’m moving fast. Took a bit to get the tension right, but once it’s set, it’s perfect. Exactly what I needed for a clean, low-profile setup.

Install was straightforward—dropped the MP2 in and my 556 mags sit rock solid without any wobble when I'm moving around. Only gripe is the fit is a touch tight with the thicker mags, but it's broken in nicely after a few range days.
