AC 556 gas block
Michael
Location: OH
Date: December 29, 2024
Looking for the right piece to finish a customized 580. Barrel chop with pin and weld, and a Samson folding stock. It's about 1.5 inches longer than an original AC 556. Samson parts made the build possible. Wish I could post the pictures.
