Aluminum nozzle with a single o-ring, used in the majority of M4 builds. If you're having feeding problems with 21.4mm try the shorter 21mm nozzle.
Our nozzles come with 2 o-rings, essentially a fat and a thin one, this gives you a choice of fitment since the outer diameter of cylinder head shafts can vary. As always please ensure you use small amount of silicone grease on the oring.
