October 2026 so far on GunPartPicker
Holosun HS510C HUD Solar Powered Circle Dot Sight ranks #19 of the 219 optics builders have added on GunPartPicker so far in October 2026, behind the EOTECH EXPS3-4 HWS and G45 Magnifier, with about 1% of all optics added to builds. Up from #20 in September. Builds with this optic are mostly chambered in 5.56 NATO (66%, then 300 Blackout 22%), split between carbine-length (33%) and pistol-length (28%) gas systems, and nearly all AR-15.
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today 10 of the 11 retailers we track have it in stock. It dipped to $272.79 at MidwayUSA for a stretch in September 2026, well under its usual $309.99, so sales do come around. Buying today, the lowest price is $309.99 at Brownells, above September's low of $272.79, so a better deal may come back.
