This sight is the scaled-down version of the legendary RMR, offering the same rugged reliability and accuracy in a more compact design, making it ideal for concealed carry applications.

My Experience

I had the chance to test the RMRcc extensively, and I must say, it is one exceptional piece of equipment. Transitioning from a full-sized RMR to an RMRcc was initially noticeable, but within a few rounds, the difference was negligible. My shots were as fast and as accurate as with the larger optic. The automatic brightness adjustment and the overall robustness of the sight truly stood out.

  • Rugged construction: Manufactured from 7075-aluminum for maximum durability.

One of its prominent features is the 6 MOA dot, which is neither too large to hinder precision nor too small to spot quickly. 

Its durable 7075 T6 aluminum housing ensures it can handle challenging outdoor scenarios. 

Compatibility: The Taurus GX4 models can accommodate the HS407K-X2 owing to their modified RMSc footprint. Installation is as straightforward as removing the pins in the rear of the slide and directly mounting the Holosun 407K.

My Experience

The HS407K-X2 exceeded my expectations on multiple fronts. The 6 MOA dot quickly grew on me – it was just the right size to locate easily without obscuring the target. 

The side-loading battery tray was a significant convenience, eliminating the need for re-zeroing every time I had to change batteries. All these factors combined made the HS407K-X2 a delight to use.
