Our Ultra Light Bolt Carrier is the lightest durable bolt carrier possible made of steel. Forget about aluminium bolt carriers - they just don't last. Smooth cycling and resistance to wear is essential.
 
The lighter bolt carrier is, the less gas you'll need for cycling, the less recoil you feel leading to less muzzle rise and longer life span of the rifle.
 
Adjustable gas block is a must.
 
Gas key with bolts is attached and stacked. ​Bolt head, cam pin, firing pin and firing pin retainer pin not included.
