The MMP-556 is the first pistol we introduced in our line, and has continuously been one of our best sellers. These pistols are built to be the functional tool that the end user needs to meet and overcome any challenge.
At the heart of our pistols, we use our M16 cut nitride bolt carrier group, matched with a fully nitrided Ballistic Advantage 10.5” carbine-length barrel. Our carbine-length gas system provides an extremely soft and controllable recoil impulse. We then paired these components with our tight fitting receivers, and ultra-rigid 9” M-LOK rail system to provide a pistol that is up for any task.
Our MPP-GI trigger has micro polished contact surfaces, and a fitted disconnector. This combination gives you the 5lb weight of a typical duty trigger, and removes all of the gritty drag while breaking the shot. Our fitted disconnector gives a positive, short reset that is hard to miss!
We finish out our MMP-556’s with a four position SB Tactical SBA3 pistol brace, which is our choice for comfortable braced shooting.
