October 2026 so far on GunPartPicker
Cryptic Coatings 5.56 NATO AR-15 Bolt Carrier Group - Mystic Bronze is the fourth most added bolt carrier group on GunPartPicker so far in October 2026, behind the Wilson Combat M16 Bolt Carrier Assy 5.56 NATO Polished Black Nitride, with about 7% of all bolt carrier groups added to builds. Down from #3 in August and September. Builds with this bolt carrier group are mostly chambered in 5.56 NATO (80%, then .223 Wylde 9%), mostly on mid-length gas (61%, then carbine-length 23%), 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 both retailers we track have it in stock. Prices barely moved in September 2026, holding around $217.99, so there haven't been real sales lately. Buying today, the lowest price is $217.99 at Optics Planet, which matches the best price we saw in September.
