August 2026 on GunPartPicker
NCSTAR Vism PRO Series Flip-Up Rear Sight was the fifth most added rear sight on GunPartPicker in August 2026, behind the Mission First Tactical AR-15 Rear Sight Flip Up Polymer Black, with about 8% of all rear sights added to builds. Down from #4 in July. Builds with this rear sight are mostly chambered in 5.56 NATO (67%, then .223 Wylde 33%), split between mid-length (50%) and rifle-length (50%) gas systems, and mostly AR-15 (75%, then AR-10 25%).
It was hard to find in August 2026, in stock on only 7 of the 18 days we checked, and today only Classic Firearms has it in stock. Prices barely moved in August 2026, holding around $38.99, so there haven't been real sales lately. Buying today, the lowest price is $38.99 at Classic Firearms, which matches the best price we saw in August.
