AR15 Bolt Carrier Group Rehab Kit in 5.56 for Worn BCGs
The AR15 Bolt Carrier Group Rehab Kit in 5.56 brings together essential, heat-treated internal components to restore a worn bolt carrier group toward factory performance. It's a practical option for builders and gunsmiths maintaining a 5.56 AR-15 BCG that has seen heavy round counts, helping return reliability without replacing the entire assembly. Made in the USA.
Use this kit as part of routine maintenance or when refreshing an aging carrier. Confirm the kit components match your existing parts before installation, and inspect your bolt and carrier for wear during reassembly. If replacement makes more sense, compare a complete M16 BCG with billet extractor in 5.56 nitride or a complete VKTR DI carrier group.
Builders working on the lower can also stock spare detents and pins, such as the AR15 fire control group pin ten pack, to keep maintenance projects moving.
