Holosun HS510C Red Dot & HM3X Magnifier Combo ranked #26 of the 210 optics builders added on GunPartPicker in August 2026. Builders have been adding it to their builds on GunPartPicker since February 2026. All time, it ranks #38 of the 481 optics builders have added.

Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today the one retailer we track has it in stock. Prices barely moved in August 2026, holding around $484.99, so there haven't been real sales lately. Buying today, the lowest price is $484.99 at Primary Arms, which matches the best price we saw in August.
