August 2026 on GunPartPicker
Magpul MBUS Gen 3 Folding Front Sight ranked #16 of the 30 front sights builders added on GunPartPicker in August 2026. Builders have been adding it to their builds on GunPartPicker since April 2026. All time, it ranks #15 of the 60 front sights builders have added. Builds with this front sight are nearly all chambered in 5.56 NATO, nearly all on mid-length gas, and nearly all AR-15.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today both retailers we track have it in stock. Prices barely moved in August 2026, holding around $37.95, so there haven't been real sales lately. Buying today, the lowest price is $37.95 at AR15 Discounts, which matches the best price we saw in August.
