Upgraded Ruger MK IV Pistol Frames

It seems easy enough: you push a button, remove the upper, install a new one, and you are ready to go.

This idea may work initially but can soon become an inconvenience. You might have somebody at the range with you looking to shoot or maybe you have one set up designed to run with a suppressor. If you are like me, you might have enough spare parts lying around that you could build a complete pistol.

There's no denying that the Ruger® MK IV™'s push-button takedown system is as simple as it gets. Having a lower frame for each upper can make things even easier.

You may have our Mamba uppers in multiple lengths, a factory upper left as a spare, or you could have one set up for a red dot and one for iron sights, and you want to transition more easily between the two.

Our Upgraded Ruger® MK IV™ Frames are made of the same frame and parts used in our Black Mamba pistols. They are ready to pair with any upper designed for the Ruger® MK IV™.

These upgraded frames have been retrofitted with our Accurizing Kit, which provides a crisp, clean 2.25 lb trigger pull.

They are available in the MK IV 22/45 and the MK IV standard target frame.
