Build history on GunPartPicker
Builders on GunPartPicker first added the Luth-AR AR-15 A2 Rear Sight Aperature to a build in February 2026.
It was hard to find in September 2026, in stock on only 6 of the 21 days we checked, and today only Optics Planet has it in stock. Prices barely moved in September 2026, holding around $9.39, so there haven't been real sales lately. Buying today, the lowest price is $10.99 at Optics Planet, above September's low of $9.39, so a better deal may come back.
