Available on back-order
The Holosun HS503R is a 20 mm micro red dot sight for rifles, carbines and shotguns that combines Holosun’s Multi-Reticle System with a rotary brightness switch. You can run a 2 MOA dot alone for precision or the 65 MOA circle-dot for fast close-range work, with up to 100,000 hours of battery life in dot-only mode and 15,000 hours with the circle-dot from a single CR2032. The 6061-T6 aluminium body is IP67 rated and comes with both a lower 1/3 co-witness mount (1.63 in) and a low mount. The rotary control makes it a favourite for shooters who want a dependable, no-menu red dot on an AR-pattern rimfire, lever gun or shotgun.
What is the difference between the HS503R and the HS503CU? Both have the 2 MOA / 65 MOA MRS reticle. The 503R uses a rotary switch with no solar panel; the 503CU uses push buttons with Solar Failsafe and Shake Awake.
How long does the battery last? Holosun rates the HS503R at up to 100,000 hours with the dot only and 15,000 hours with the circle-dot reticle, on setting 6, from one CR2032.
Which mount do I use? The 1.63 in lower 1/3 co-witness mount suits AR-style flat-top rifles; the low mount suits rifles and shotguns with a low comb.
