Holosun EPS vs Trijicon RMR Type 2

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

The biggest cited difference is the footprint and battery: Holosun lists the EPS-RD-2 as an enclosed 2 MOA sight on the K Footprint with a CR1620 and an RMR-to-K plate included, while Trijicon lists the RMR Type 2 Adjustable LED as a 3.25 MOA dot with a CR2032 and says it has the same mounting footprint as the original RMR Type 1. Figures are copied from each maker’s product page (plus Trijicon’s RMR spec sheet), checked November 5, 2026.

Like for like: the two battery-life figures use different settings and units (Holosun: 50,000 hours at setting 6; Trijicon: over 4 years at setting 4 of 8), so we do not convert or compare them. The RMR window figure comes from Trijicon’s spec sheet PDF, not its product page; the EPS window figure is from Holosun’s page. We read the Adjustable LED RM06-C-700672 page only. This page covers the EPS-RD-2; it is a different model from the EPS Carry. Both makers print a price; we list none.

Which to pick (on paper)

If your slide is cut for the K footprint: the EPS-RD-2. Holosun lists the K Footprint.
If your slide is cut for the RMR footprint: either on paper: Trijicon states the RMR footprint, and Holosun includes an RMR-to-K plate with the EPS-RD-2. Check fit against your slide and the footprint chart.
If you want the emitter enclosed: Holosun describes the EPS-RD-2 as enclosed. See enclosed vs open emitter. We did not find an enclosed or open label on the RM06 page.
If weight and size matter: the RM06 lists 1.2 oz and 1.8 x 1.1 x 1 in; the EPS-RD-2 lists 1.4 oz and 1.63 x 1.19 x 0.99 in.
If you want the larger dot or the wider window: the RM06 lists 3.25 MOA; the EPS-RD-2 lists 2 MOA and a 0.90″ × 0.63″ window against .87 x .63 in.

We have not range-tested these; facts above are from the makers.
