October 2026 so far on GunPartPicker

Forward Controls Design GBF .750 Low Profile Gas Block - GBF is the seventh most added gas block on GunPartPicker so far in October 2026, behind the Bravo Company AR-15/M16 .750 Low-Profile Gas Block, with about 4% of all gas blocks added to builds. Up from #9 in September. Builds with this gas block are nearly all chambered in 5.56 NATO, mostly on mid-length gas (81%, then carbine-length 19%), and nearly all AR-15.

It was in stock most days in September 2026, but today 2 of the 6 retailers we track have it in stock. Prices barely moved in September 2026, holding around $57, so there haven't been real sales lately. Buying today, the lowest price is $61.75 at Optics Planet, above September's low of $57, so a better deal may come back.
