Holosun 507K X2 vs Trijicon RMRcc

By Cole Harlan, EditorUpdated Nov 5, 2026How we verifyEditorial standards

The biggest cited difference is the footprint and reticle: Holosun lists the HS507K-X2 on the Holosun K footprint with a selectable 2 MOA dot and 32 MOA circle, while Trijicon lists the RMRcc (3.25 MOA model) as a single 3.25 MOA dot on its own RMRcc footprint, which is neither the RMR Type 2 nor the K. Figures are copied from each maker’s product page, checked November 5, 2026.

Like for like: *Trijicon’s product-page SPECS list 1 oz (28.35 g), while Trijicon’s RMRcc spec sheet lists 1.2 oz (34 g) with battery. We use the product page in the table and note the sheet here; the two may use different bases, which we cannot confirm. The Holosun 1 oz figure is its page value. The battery-life figures use different settings (Holosun: 50,000 hours; Trijicon: over 4 years at setting 4 of 8), and the water ratings use different standards (IP67 vs 66 ft), so we do not rank them. Trijicon also lists a 6.5 MOA RMRcc (CC07); this page covers the 3.25 MOA model. Prices are what the pages printed on the check date, not street prices.

Which to pick (on paper)

If your slide is cut for the K footprint: the HS507K-X2. Holosun lists the K footprint; Trijicon lists the RMRcc as its own footprint. See the footprint chart.
If you want a switchable dot and circle: Holosun lists the Multi-Reticle System; the RMRcc 3.25 MOA model lists a single dot.
If battery type matters: Holosun uses a CR1632 in a side tray; Trijicon lists a CR2032.
If you want the larger dot: the RMRcc at 3.25 MOA against the 2 MOA dot in Holosun’s reticle.
If the printed price matters: $348.22 on Holosun’s page against $734 on Trijicon’s.
