Reproduction AKS-74U barrels made by AK-Builder.
- Chrome lined
- 5.45x39
- Correct 1:6.3" twist rate
- 22mm chamber diameter
AK-Builder makes their rear sight block journal oversized to accomodate all surplus blocks, which results in an overly tight fight with my hinge blocks (made to the tightest spec to accomodate all barrels).
These barrels have been turned down to be a perfect fit with my blocks.
