Features and Benefits of Holosun 507c vs. Trijicon SRO

These features, as well as the benefits mentioned, are what make these products worthwhile. You can determine which product meets your preferences using these benefits.

1. Optic clarity and Reticle

We need excellent optic clarity and a better reticle possibility in order to see clearly while shooting and reach the target. Combining these two options results in a satisfying feeling of “hitting the target.”

Holosun 507c

The window size of Holosun 507c is 0.63 x 0.91 inches which are perfect for viewing the target fully and the area around the target for a better hit. With the large field of view, the optic clarity is also good due to the multi-layer lens coating, which also protects the optic window. This multi-coated reflective coating is made to enable maximum light transmission.

Two reticle colors—red and green—are offered by Holosun 507c on the market. You can purchase these colors separately, one in each optic, depending on your preferences. Buy two optics if you want to use both reticle colors.

The Reticle in Holosun 507c has advantages that I, along with many other people, find appealing. The multiple reticle system, which enables you to switch between three different reticles—2 MOA, 32 MOA, and simultaneously both dot and circle—offers this advantage. The 2 MOA dot represents precision or accuracy, whereas the 32 MOA circle represents target acquisition speed. Therefore, when you switch to the options of using a dot and a circle at once, you will hit the target with precision and move toward it quickly. This window lens and Reticle offer unlimited eye relief, and the Holosun 507c is also parallax free, allowing the shooter to shoot with ease.

Trijicon SRO

The Trijicon SRO has excellent optic clarity and an unobscured field of view, which together give the shooter a full vision. You can see more of the surroundings of the target credit goes to Trijicon SRO’s large window. Trijicon SRO provides limitless eye relief with no strain at all. Additionally, it has a parallax-free reticle that won’t blur even if you shake while holding the weapon or optic.

The Trijicon SRO has three different reticle options but no multiple reticle system. The 1 MOA dot is the finest dot you will ever find in an optic that offers high precision and is the first reticle option. The second reticle choice is the 2.5 MOA, which is another highly accurate dot. The third is the 5 MOA, a slightly larger dot that provides more precision and faster target acquisition than the 1 and 2.5 MOA dots.

Winner: Holosun 507c

Holosun 507c outperforms Trijicon SRO in terms of optic clarity and Reticle by offering a multi-layer coating on the lens and multiple reticle systems.

2. Durability and Reliability

How long will your optic last, and what assistance will the brand provide if the product is damaged? When it comes to safety, toughness, and dependability, there are two things to take into account.

Holosun 507c

Holosun products are known for their protracted durability; the housing material used in the holosun 507c is “7075 T6 Aluminum.” This material is then anodized to give the optic a matte finish for improved durability and rust resistance.

Holosun optics are water-resistant and shock-resistant, allowing them to be used in the rain, in water up to 1 meter deep for thirty minutes, and without damage. I put these products to the test to see if they lived up to the durability claims made by holosun and holosun 507c. Furthermore, there are drainage holes on both edges of the optic that allow excess water to flow out without impacting the optic by entering it.

Holosun provides a limited lifetime warranty that allows you to get a new optic if you receive a faulty optic from them. Furthermore, if your product is damaged by a fall or if water enters the optic, holosun will repair it. In the event that the damage is severe, holosun will not fix or replace your product.

Trijicon SRO

Trijicon SRO is constructed of “7075 T6 Aluminum,” the same material as Holosun 507c, which provides exceptional durability. Trijicon SRO has a smooth texture and is rust-resistant due to the alloying of this aluminum. Additionally, the Trijicon SRO has a tough lens frame that guards against scratches even if the optic is dropped from shoulder height or higher.

Trijicon SRO, like holosun 507c, is shock- and water-resistant, allowing your optic to function properly in foggy, rainy, and snowy conditions as well as to withstand damage like scratches and falling. Don’t worry. I ran all of these tests on the Trijicon SRO, and it passed with flying colors.

Trijicon’s warranty is limited to 5 years, during which time the company will repair the product if the damage is minor and replace the product if you receive a faulty optic.

Winner: none

Since both the holosun 507c and the Trijicon SRO offer the same level of toughness and dependability, there is no clear winner. They use the same housing material, have the same water and damage resistance, and have the same time limit warranty.

3. Size and Weight

The size and weight of the optic are significant for mounting and carrying it with ease. Now take into account the Holosun 507c and Trijicon SRO’s size and weight.

Holosun 507c

The holosun 507c is a compact red dot sight, taking measurements 1.78 x 1.15 x 1.15 inches. The Holosun 507c optic weighs only 1.5 ounces, which, in my opinion, is not a lot. No case of comprising, Holosun 507c is actually compact and lightweight.

Trijicon SRO

The Trijicon SRO is a compact sight with measurements of 2.2 x 1.3 x 1.4 inches. It weighs only 1.6 ounces. In comparison to the holosun 507c, this is not very similar, but SRO is still less lightweight and compact.

Winner: Holosun 507c

Both the Holosun 507c and the Trijicon SRO are small and light, but the Holosun is superior to the Trijicon because it is smaller and weighs one ounce less.

4. Source of power

For how long will your optic function, and will it be helpful in case of an emergency?

Holosun 507c

Holosun 507c uses “CR-1632,” a lithium battery cell that will last up to 10,000 hours to 50,000 hours depending upon the brightness level you set and the Reticle you will choose. Holosun 507c battery will last longer if you choose the dot reticle and set the brightness on level 4. Furthermore, the battery will not last long if you choose the option of using both reticles at once and setting the brightness to full.

The battery compartment of the holosun 507c lies under the optic, and it has two features that make the holosun 507c purchase worthwhile. The first one is the shake-awake technology which will automatically turn on and off the optic LED depending upon the motion. The second one is the silicon solar cell which powers the optic in case of battery failure. This solar failsafe feature saves life in case of danger by providing extra life to the optic. 

Trijicon SRO

Trijicon SRO has a long-lasting “CR-2032” lithium battery cell and a top battery compartment. This top placement of the battery compartment will allow you to replace the battery without removing the optic from the weapon. Trijicon SRO batteries have a maximum operating life of 30,000 hours when set to medium brightness or level 4.

Winner: Holosun 507c

Holosun 507c outperforms Trijicon SRO big ups to its longer-lasting battery, shake-awake feature, and solar failsafe.

4. Brightness Adjustment

To see the Reticle clearly for perfect aim, brightness adjustment levels are important to consider. 

Holosun 507c

Holosun 507c offers twelve levels of brightness that can be changed based on requirements or preferences. There are two levels for night setting and ten levels for daylight setting out of these 12 adjustment levels. The two additional levels for night vision increase the value of holosun 507c.

Furthermore, holosun 507c provides three operational modes to support safe shooting. These functional modes include:

• Automatic mode
• Manual mode
• Lockout mode

The automatic mode, which automatically adjusts brightness in accordance with ambient light, is the holosun 507c’s default setting. You could change the brightness using the manual mode to suit your preferences or requirements. The lockout mode locks the manual settings to prevent any unintentional changes from happening when they are dropped. By pressing and holding the “+” button for three to four seconds, you can turn these modes on/off.

A sleep mode that turns the optic off automatically after 10 minutes of inactivity is available in addition to the three operational modes. There are only a few options for sleep mode, including 10 minutes, 1 hour, and 12 hours, and disable sleep mode.

Trijicon SRO

Trijicon SRO offers eight brightness levels, six of which are for daylight settings and two of which are for nighttime settings. Trijicon SRO’s one level is where the bright dot is located. With these adjustment buttons, reticle brightness issues are a thing of the past.

Trijicon SRO has a variety of brightness adjustment mechanisms from which to choose. The first one is the manual mode, to manually adjust the brightness. The lockout mode, which automatically sets and locks the Reticle’s brightness, is the second. The lock-in mode, which locks the manually adjusted brightness, is the third option.

Winner: Holosun 507c

Holosun 507c outperforms Trijicon SRO by providing twelve brightness settings, three operational modes, and a sleep mode.

5. Windage and Elevation

To zero the sight for hitting the target perfectly, windage and elevation setting are necessary. 

Holosun 507c

Holosun 507c offers excellent windage and elevation adjustment settings with a maximum adjustment range of 50 MOA. Two tools are provided in the box for these changes.

Trijicon SRO

The Trijicon SRO is a tool-free design optic, so zeroing the sight presents no problems at all. It has up to 150 MOA of windage and elevation options, with 1 MOA adjustment per click. Furthermore, once you zero the sight, the Trijicon SRO will retain its zero even if you start changing the battery or make other modifications. You can drop the optic, and it will still maintain zero.

Winner: Trijicon SRO

By maintaining zero even after dropping, smashing, or replacing the battery, Trijicon SRO defeats Holosun 507c.

6. Footprint

What footprint do they use for mounting?

Holosun 507c

Holosun 507c uses an RMR footprint, which is broadly available and won’t cause you any issues down the road.

Trijicon SRO

Trijicon SRO also makes use of the RMR footprint in order to be easily mounted on the weapon. The Trijicon SRO has the advantage of having a widely used footprint.

Winner: none

Holosun 507c and Trijicon SRO have the same footprint, so there is no winner in terms of footprint.

7. Price Comparison

Since not everyone can afford expensive optics, the majority of people are worried about the prices. The price difference between the Holosun 507c and the Trijicon SRO is significant.

The Drawbacks of Holosun 507c and Trijicon SRO
