This forward assist is commonly found in mid-length gas system builds chambered in 5.56 NATO, making it a practical choice for those setups.
Specifications
Build history on GunPartPicker
Builders have been adding the WMD NIB-X Forward Assist Assembly to their builds on GunPartPicker since February 2026. All time, it ranks #47 of the 63 forward assists builders have added. Builds with this forward assist are mostly chambered in 5.56 NATO (71%, then .223 Wylde 17%), split between mid-length (43%) and carbine-length (24%) gas systems, and nearly all AR-15.
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today only Primary Arms has it in stock. Prices barely moved in September 2026, holding around $17.55, so there haven't been real sales lately. Buying today, the lowest price is $17.55 at Primary Arms, which matches the best price we saw in September.
