If you are building a LIMA SIX build kit, it is required to drill a new gas port in your AR15 barrel. While the kits come with a drilling jig and drill bits, we understand that some people may not be comfortable drilling their barrel. You can send us your barrel and we will drill the port, plug the existing port, and dimple your barrel for perfect gas block alignment.
