Description

The Holosun 407K X2 Red Dot is a micro compact pistol red dot sight that features a 6 MOA dot and a modified RMSc a.k.a. K-Series Footprint. It is intended to be used on sub compact and micro compact pistols with the properly cut slide.

The 407K X2 will fit directly on slides that have a K Series footprint, but will require an adapter plate for pistols with an RMSc footprint. 

The 407K X2 is one of the best value micro red dot pistol sights on the market. It features a slim sleek profile, a strong 7075 T6 aluminum housing, side removable battery, shake awake, 2 nightvision modes, 50,000 hours of battery life, a bright emitter easily visible in bright sunlight, manual brightness controls, and IP67 waterproof rating.

This tough and reliable pistol red dot sight from Holosun is one of their lowest priced micro pistol red dot sights. The 6 MOA dot is great for short to mid range. It’s a nice size dot to pick up on the screen and to get on target quickly.

Holosun 407K X2 Red Dot FAQ

  • What is the difference between 407K and 507K?
    • The 407K has a 6 MOA Dot and the 507K has the MRS (Multi Reticle System) which is a 32 MOA Circle and 2 MOA Dot. By holding down the "-" button for 3 seconds you can toggle between the 32 MOA ring only, 2 MOA dot, or both the ring and the dot.
  • Do 407K and 507K have the same footprint?
    • Yes they both have a modified RMSc footprint.
  • What is the difference between the Holosun 407C and 407K?
    • The Holosun 407C has an RMR footprint and is larger than the 407K. The Holosun 407C also has a solar failsafe, auto brightness setting, and a 2MOA dot. The 407K has no solar panel, or auto brightness mode, and has a 6 MOA dot.
  • What is the difference between Holosun 407K and 407K X2?
    • The 407K X2 is the latest version of the 407K. There was an older version which was not the X2 model. Today the 407K X2 is the only model on the market with that name, it is commonly referred to as the 407K.
  • Which is better Vortex or Holosun?
    • Holosun is better because they have a better track record, longer battery life, and better features, controls, reticles, and reticle colors.

Gonna take practice

Good product. easy to install on my Beretta, took ten minutes to set it up. The hard part is getting to be able to draw and come up every time with the dot in the Lense. Its getting better the more I practice. It takes patience and a lot of time.
