Trijicon Sro vs Holosun 507c- How do they compare?

  • Reticle performance

The reticle in an optical sight is necessary for bringing the gun in the same horizontal plane with the target, and every sight has been equipped with its unique vision, which makes them adaptable for use in different applications, the reason why you should choose the one that makes shooting comfortable. The Trijicon Sro will, therefore, furnish you with a 2.5MOA red dot, which has been known to be effective when dealing with smaller targets of about 100yards.

The Holosun 507c will furnish you with a 2 MOA dot and a 32MOA circle complete with up to 4 positioning points. The diameter of the incorporated circle in the Holosun represents up to 32 inches 100yards, and for accurate target acquisition you can hold the button down for up to 3 seconds, so that you can switch between the three circles, meaning that you will either get the dot, the circle or the circle plus the dot.

The Holosun 507c therefore, is the better unit because it allows users to choose between the three circles with regards to the target they are pursuing and the environment, which includes the lighting conditions.

  • Battery performance

When it comes to powering and the battery performance the Holosun 507 is the better unit because it combines the dual power of the solar and battery, but be sure not to use a rechargeable battery. What’s more, is that if you use the high-quality battery then your device will be able to give you up to 10,000 hrs but that is for both the dot and the circle.

But if you are using the dot at the 6th setting then you will get an enhanced 60,000hrs. Trijicon’s battery is pretty simple, coin-like; loading is super easy as it is done from the top and doesn’t interfere with the sight.

  • Objective lens performance

Trijicon provides you with a large objective lens, and the only downside with this feature is that it adds to the weight of the sight, but on the flip side, you will enjoy using it because critical eye positioning is not of the relevance here rather the ability to see the dot. The above then means that you will be able to acquire your target even with both your eyes open.

The unit is additionally parallax free and can be used with the suppressor height iron sights. For the Holosun 507, you will be provided with a canted objective lens. And the reason for the above is to help create a proper reflection of the dot. Important to note is that this sight comes incorporated with LED on the internal sides of the tube, so for better viewing the lens has to be perpendicular to the LED. The Holosun 507 therefore, emerges as the winner because the angle of the objective lens helps reduce the reflections of the target.

  • Water resistance

Water-resistance in a sight means that the unit will better be able to work in an environment that has a lot of moisture without affecting performance. Both the Trijicon and the Holosun are water resistant but are differently tolerant with Trijicon offering the best tolerance in water as it will provide the best performance even when submerged up to 3meters deep into the water.

Holosun on the other hand still offers good performance as it is IP67 waterproof meaning that it can tolerate being submerged in a 1-meter deep water body for approximately 30 minutes.

Trijicon Sro vs Holosun 507c – A Comparison Overview

Trijicon Sro

If you have interacted with most of these sights, you will notice that the Trijicon Sro offers the same footprint as the RMR, thus mounts pretty easily. What’s more is that users have been given the liberty to tweak the 8 brightness settings, using the 3 adjustment modes, which consequently enables control of the dot in the various shooting situations.

And even more interesting is that you will be provided with up to three different dot sizes, the first one being the 1.0 dot size, which comes effective where increased accuracy at a distance is relevant. You then get the 2.5 MOA dot size which is versatile and can, therefore, be used in the various shooting applications. Lastly, we have the 5.0 MOA dot size, necessary for engagements where speed and recovery is of the utmost importance.
