Ar-15 Gas Block Aligner - Gas Block Aligner 30 Caliber

Plastic segmented rods fit into AR-15 gas ports and help you find correct alignment between barrel and gas block. Rods come in 6-paks, and in different lengths and diameters to fit the different gas port specs used by various manufacturers. Segmented construction lets you break the rod off with standard cleaning rod, and high-visibility orange color makes it easy to verify both portions are out of the gas system and barrel. Available in .22 Cal for .223/5.56 and .30 Cal for all calibers from .223/5.56 up to .30 caliber. Includes instructions. Mfg: Uniquetek
