October 2026 on GunPartPicker

LMT Defense 5.56 F-A BOLT CARRIER GROUP ranked #24 of the 258 bolt carrier groups builders added on GunPartPicker in October 2026, behind the Geissele Automatics 5.56 Enhanced AR-15 Bolt Carrier Group - Nanoweapon, with about 1 in every 167 bolt carrier groups added to builds. This is its first month in the rankings.

It was hard to find in October 2026, in stock on only 14 of the 27 days we checked, and today both retailers we track have it in stock. Prices barely moved in October 2026, holding around $249.75, so there haven't been real sales lately. Buying today, the lowest price is $249.75 at AR15 Discounts, which matches the best price we saw in October.
