The fit and finsh is very nice and works great. You will need to check the extractor roll pin and file it down if necessary. The pin protrudes as it cannot come out on the other side due to the gas key carrier which is a solid piece for blow back design. Just file it down and your set.

Extractor roll pin backed out In less than 50rnds… Caused feeding issues and chewed up my magazines feed lips. Was able to tap it back in but it was deformed from dragging on the magazine… Filed it down. Will test it again soon.
