[QUOTE="SPDguns, post: 3005304, member: 17621"] Bear with me while I try to explain this--Make sure that the gas hole in the barrel is lined up with the hole in the gas block parallel to the bore axis (front to back). Some blocks don't take into account that the front handguard cap is missing, thus making the gas block too close to the upper receiver the distance of the thickness of the cap. The solution is to install a shim washer the thickeness of the missing cap to push the gas block forward into the correct position. [/QUOTE]
