Hey Freedom Gorillas today we are going to explain the similarities and differences between the Holosun 508T X2 and the 507 X2. We understand that it can be difficult to understand the differences when you don’t have them both in your hands.
Ok so lets get into it. The first thing to know about the Holosun 507C X2 and 508T X2 is that they have an RMR footprint. This means you’ll need to know the footprint of your pistol and will need to know if these will fit. You can check out our fitment guides here and they will explain which Holosun optics fit your pistol and any type of adapter plate you may need.
TLDR: The main difference between the 508T X2 and the 507C X2 is that the 508T X2 has a square shaped window and housing and is made out of titanium which makes it more durable than the 507C X2 which is made out of 7075 T6 Aluminum. Both the shape of the 508T X2 and the material make it stronger. The 508T X2 is one of the strongest and toughest pistol optics on the market.

Holosun 508T X2 vs 507C X2 Footprint
The footprint on the 508T X2 and the 507C X2 are the same, they are both RMR footprints.
This means your pistol must have an RMR cut slide or you must have an RMR adapter plate. If you do not then these will not fit your pistol.

Both the 508T X2 and the 507C X2 are full size pistol optics. They are meant to be mounted on full size or compact pistols. They are not intended for slimmer and micro compact pistols.
When mounted on your pistol they may have some overhang on the slide but not much.

Holosun 508T X2 vs 507C X2 Reticles
The 508T X2 and the 507C X2 have the same reticle system. They both come with the MRS (multi reticle system), which is a 32 MOA outer ring and a 2 MOA center dot.
The reticles can be toggled to use either the 2 MOA dot only, 32 MOA circle only, or both together by holding down the "-" for 3 seconds.
The 508T X2 and the 507C X2 also both come in red or green reticles.
Holosun 508T X2 vs 507C X2 Battery Life
The battery life on the 508T X2 and the 507C X2 are exactly the same. They are both rated at 20,000 hours of battery life on setting 6 when using the MRS reticle or 50,000 hours of battery life on setting 6 if using the 2 MOA dot only.

Holosun 508T X2 vs 507C X2 Which is Better?
As you can see the main difference between the 507C X2 and the 508T X2 is that the 508T X2 has a square shape and is made out of titanium. Both the titanium and the square shape are to make the 508T X2 more durable.
So which is better? Well the 508T X2 is $60 more than the 507C X2 so you have to ask yourself if you need that extra durability or if you prefer a more rectangle shaped window.
The 508T X2 is essentially a “Duty” version of the 507C X2. The 507C X2 is still plenty durable, however it’s a fact that the 507C X2 oval shape top can not take as much of a beating hitting the ground as the 508T X2’s square shape.
Internally both are the same, it’s just the material, shape, and intended use that’s different.
