The AR-15 BoltLock is a practical protective device designed for AR-15 upper receivers.
It fully encloses and secures the bolt carrier group, protecting it from dust, dirt, and damage during storage and transport (not intended for live-fire operation).
Thanks to its optimized geometry, the BoltLock provides complete coverage inside the upper receiver for improved protection and stability.
Important Notice:
The BoltLock is intended only for protection and fixation of the bolt. It does not replace legally required transport or safety devices.
