Holosun has been a formidable competitor in the world of firearm optics. Among some of its most successful and cherished products was the 507C V2, which came out in early 2020. However, fate had different plans for it. Shortly after, Trijicon sued Holosun for infringement.
Sometime later, the two competitors announced a settlement, but the terms of the agreement were not disclosed. The result of the lawsuit was Holosun redesigning the optic to look slightly different. Holosun ended up discontinuing the V2, but released the third generation which was labeled ‘X2’.
The two are, therefore, essentially the same except for the obvious difference in the forms. The V2 had larger, ergonomic buttons and the X2 had gone back to the smaller-sized buttons of the previous models. All other upgrades that had people curling their toes were still there at a decent price.
Reticle
Both the optics boast of a multi-reticle system (MRS) with three options; the good-old circle dot (65 MOA circle and 2 MOA dot), classic 2 MOA and the bigger 32 MOA. All work well but you can switch them up depending on the distance you’re shooting from. Generally, rifles go with 2 MOA and shotguns with 32 MOA.
The chances of losing the zero are pretty low too. The optics are known to hold the zero even after rigorous use. Moreover, there are overall 12 brightness settings, with 10 of them compatible with day vision and 2 of them for the night.
Battery and Running Time
The addition of a side battery compartment was a huge improvement from the previous models. In the earlier models by Holosun, the battery compartment was at the bottom and you had to dismantle the sight to replace it. Now you can seamlessly change the batteries without having to worry about smithing the optic back together and re-zeroing later.
All Holosun 507C versions have two power options, one being the battery (CR1632). The other is provided by the Solar Failsafe system. To conserve the battery life, in auto mode only, when the cell is receiving sufficient natural or artificial light, the optic will switch to the solar-equipped system.
This feature fails in the absence of light though, unlike in some other models which are equipped with supercapacitors and run night and day.
The intensity of the reticle will also vary with the external light. You can also make the optic only rely on the battery by manually adjusting the settings.
The battery life is different for different reticles. It would be 50,000 hours if you go with the 2 MOA and would decrease to 10,000 if you’re a 32 MOA fan.
Then there’s also the Holosun Shake Awake tech to conserve the battery. You stop moving the optic, it shuts off and turns back on with the slightest shift.
Mounting Options
The Holosun 507C, both X2 and V2, are small, compact, lightweight and built from anodised 7075 T6 Aluminium. The dimensions are 1.78 × 1.15 × 1.15″ and 0.63 × 0.91″ for the window and they weigh around 1.5 oz.
These specifications show the greater adaptability of the optics with handguns or arms that can be concealed and carried. But this doesn’t necessarily limit them to handguns, it only means they need a mount for use on a rifle. Both come with a Picatinny mount, which would generally do the trick for most AR rifles.
Features
Holosun’s open-reflex optical sights come with a variety of features that have, together with their reliability, made them eligible for use on both civilian and law enforcement armaments. X2 and V2 possess almost the same features.
Both the optics are constructed with IP67 water-proof tech and are shock-resistant. After taking hard continuous falls, the optics still hold the zero without much damage. In self-defense situations, these can be the ones you entrust your life to.
Neither one of them would stand out in a crowd, but they look decent. Most people might say they like bigger buttons on the V2 (and Trijicon is not a part of this crowd, of course), but some found the X2 to be a double-treat with upgraded features and smaller buttons.
In the majority of the cases though, people don’t care about the size of the buttons, especially since we have Holosun’s lock mode. When you have attained a setting you like, you can lock it there so that no accidental touch can ruin it, whether the buttons are easily pressable or not.
Price
As mentioned earlier, the V2 has been discontinued and you may sometimes find it at a higher price. But both these optics can still provide what other big-shot companies provide for a very heavy price (say, Trijicon).
The lowest price I could find for the Holosun 507C X2 was at Brownell’s which was close to $300. You can click here to check the updated price and buy it.
The price for the V2 is the same but I could not find it listed anywhere new because it has been discontinued.
Conclusion
Both of these optics are the best you can find in this price range. V2 is no longer in production after the lawsuit and in its place, the X2 has the same features except the buttons have changed positions and shrunk back to their past size.
Choose either one of them, with the 50,000-hour battery life, lock mode, MRS, Solar Failsafe system and so on, you’ll get a bang for your buck either way.
