Questions & Answers
If I use this gas block with the Rosco Bloodline 14.5" barrel(BL-145-M4-556-7-C). Will the gas holes line up if I use a "NON" free-float handguard? Manufacturer Answer

The gas hole will line up utilizing any handguard, just be sure to utilize the dimple to line up the set screws.
