Product Info for Luth-AR Gas Block

The LUTH-AR Gas Block is precision machined to be fully compliant with Mil Spec. Each gas block will fit securely into a healthy AR platform to ensure that the gas port sizing does not contribute to excess wear and tear of the part. Luth-AR gas block fits securely into an AR platform to ensure that the gas port does not get pinched when installing/removing the bolt. To be used on a AR platform with a Luth-AR bolt carrier group or piston system the gas block should be installed at the bolt carrier early stage in the gas system build. Then the locking lug can be installed at this point to fully secure the gas block to the barrel.image
