Build history on GunPartPicker
Builders on GunPartPicker first added the Primary Arms SLx 3X Micro Magnifier to a build in June 2026.
It was hard to find in September 2026, in stock on only 10 of the 21 days we checked, and today both retailers we track have it in stock. Prices barely moved in September 2026, holding around $179.99, so there haven't been real sales lately. Buying today, the lowest price is $179.99 at AR15 Discounts, which matches the best price we saw in September.
