September 2026 on GunPartPicker

Magpul MBUS Flip-Up Sight Set (Front & Rear) ranked #40 of the 73 iron sights builders added on GunPartPicker in September 2026. Builders have been adding it to their builds on GunPartPicker since May 2026. All time, it ranks #26 of the 153 iron sights builders have added. Builds with this iron sight are mostly chambered in 5.56 NATO (73%, then .223 Remington 9%), split between carbine-length (33%) and mid-length (33%) gas systems, and nearly all AR-15.

It was hard to find in September 2026, in stock on only 1 of the 21 days we checked, and today only AR15 Discounts has it in stock. Prices barely moved in September 2026, holding around $84.90, so there haven't been real sales lately. Buying today, the lowest price is $93 at AR15 Discounts, above September's low of $84.90, so a better deal may come back.
