Holosun ARO RD2 Red Dot Sight 2 MOA 1X ranked #48 of the 220 optics builders added on GunPartPicker in October 2026. Builders have added it to their builds on GunPartPicker. Since April 2026, it ranks #67 of the 585 optics builders have added.

Availability is good: it was in stock at one retailer or another nearly every time we checked in October 2026, and today 5 of the 7 retailers we track have it in stock. It dipped to $109.99 at BattleHawk Armory for a stretch in October 2026, well under its usual $159.99, so sales do come around. Buying today, the lowest price is $99.99 at BattleHawk Armory, which matches the best price we saw in October.
