October 2026 so far on GunPartPicker
Radian Weapons M16 Enhanced Bolt Carrier Group Nitride is the tenth most added bolt carrier group on GunPartPicker so far in October 2026, behind the Spike's Tactical 5.56 NATO M16 Cut Lightweight AR-15 Bolt Carrier Group - Nickel Boron, with about 1% of all bolt carrier groups added to builds. Up from #51 in September. Builds with this bolt carrier group are mostly chambered in 5.56 NATO (76%, then 300 Blackout 11%), split between mid-length (52%) and carbine-length (29%) gas systems, and nearly all AR-15.
It was hard to find in September 2026, in stock on only 4 of the 20 days we checked, and today 3 of the 8 retailers we track have it in stock. Prices barely moved in September 2026, holding around $209.95, so there haven't been real sales lately. Buying today, the lowest price is $209.95 at Optics Planet, which matches the best price we saw in September.
