Holosun 507K X2: Best Price and Where to Buy

As of September 3, 2026, there is no confirmed price to judge yet for the Holosun 507K X2 red dot sight. The price table below lines sellers up as listings post, and the section on matching the exact model saves you time once they do. Current pricing is on the store button above; see how we track prices for how to tell a genuine low from a marked-up strike-through.

What the 507K X2 is, and which one to price

The 507K X2 is a K-footprint micro red dot sight for micro-compact pistols, built on a 7075-T6 aluminum housing and running a Multi-Reticle System that switches between a 2 MOA dot, a 32 MOA circle, or both. The reticle choice is the point of the design: the 2 MOA dot suits precise, deliberate aiming, the 32 MOA circle helps the eye find the sight fast, and using both together gives you a ring to catch and a dot to settle on. Shake Awake motion activation sleeps the sight when it is still and wakes it on movement, which is why the CR1632 battery is rated for up to 50,000 hours and holds up through long stretches of daily carry. Naming is where buyers slip up: this model has also appeared under the older HS507K prefix, and several near-named Holosun sights sit beside it on dealer pages, so match the exact model code and reticle before comparing any prices.

Where to buy a 507K X2

When a live price appears here, confirm the seller’s return window and warranty, and that the unit ships new and sealed, before paying, since those terms vary by who lists it. A listing that omits the X2 designation or does not state the reticle is one to pass on, because near-named optics trade at different prices and you want to be sure you are buying the exact configuration you priced. The first-party versus marketplace guide explains why the identical optic can carry different terms depending on who lists it.

When the 507K X2 price might move

Without a confirmed price yet, there is no established low to wait for. Once listings post and a history builds, you will be able to see whether a tag is genuinely cheap or simply where a seller usually sits, the read that turns a single price into a decision.

Matching the exact 507K X2 before you compare

Because the K-series names run close together, the surest way to compare prices is to fix on the exact model code and reticle you want before you shop. Confirm the listing matches the 507K X2 with its 2 MOA dot and 32 MOA circle Multi-Reticle System, on the 7075-T6 aluminum K-footprint housing, rather than a plainer or differently named build. Once you have the exact configuration pinned down, comparing that same sight across sellers is far quicker, and the price table here lines those listings up side by side as they appear.
