Howdy folks! Today at the Freedom Gorilla school of knowledge we are going to show you the size differences between the 507 Comp and a lot of other "comparable" optics out there.
As a refresher, if you aren't familiar with the 507 Comp - it's Holosun's newest competition optic. It has an RMR footprint, and a HUGE window. It has all the other Holosun goodies, like shake awake, and long battery life. It even comes with a new reticle system called the C.R.S. (Complete Reticle System) which has 7 reticles in one. Basically a 2 MOA dot with an 8, 20, or 32 moa outer circle, a 2 MOA dot only, or the 8, 20, or 32 MOA outer circle only.
The 507 Comp does not have a solar failsafe or auto brightness modes.
With that out of the way, we want to show you the size comparison of the 507 Comp vs some other optics like the Trijicon SRO and the Viridian RFX 35. These are both RMR footprint optics that have larger windows for competition use.

Why are we including the RFX 35 in this guide?
We think it's worth comparing. Viridian might not have the name like Holosun or Trijicon has in the pistol optics world, but in our research, and having our hands on the RFX 35, and it's specs - we like it. Especially because of how affordable it is.
