Specifications
Price and stock
Availability is good for the Meprolight M21T Reflex 12MOA Tri QR Reflex Sight: it was in stock at one retailer or another nearly every day in September 2026, and today only MidwayUSA has it in stock. Prices barely moved in September 2026, holding around $479.99, so there haven't been real sales lately. Buying today, the lowest price is $479.99 at MidwayUSA, which matches the best price we saw in September.
