Specifications
October 2026 so far on GunPartPicker
Magpul MBUS 3 Front Sight - Stealth Gray is the fifth most added front sight on GunPartPicker so far in October 2026, behind the Midwest Industries AR-15 Combat Fixed Front Sight, with about 6% of all front sights added to builds. Down from #4 in September. Builds with this front sight are mostly chambered in 5.56 NATO (78%, then 300 Blackout 9%), split between mid-length (58%) and carbine-length (28%) gas systems, and mostly AR-15 (93%).
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today only Magpul has it in stock. Prices barely moved in September 2026, holding around $39.95, so there haven't been real sales lately. Buying today, the lowest price is $39.95 at Magpul, which matches the best price we saw in September.
