No, you really throw off everything doing that. There is the gas tube and the gas piston and the port isn't a perfect match. If you want a bayonet lug you should use an AK-74 vertical gas block and an AK-74 gas tube. Some people have moved the Romanian gas block and redrilled the gas port in the barrel. The Romanian gas block is one of the few, besides the Norinco gas block, that isn't chrome lined.
