I broke my nexus pro priming handle so the metal one was pretty cool. However, there are a few hiccups. The priming rod pin that holds the rod to the pusher is really stiff on both the nexus pro and the worker priming kit. If you can't take the original pusher out and put it on the metal priming bar then you will unfortunately have to buy the first metal kit as well. The metal priming rod is connected to a threaded part of the pusher that requires the rest of the pusher from the A kit in order to be completed. This might just be a problem with me not being able to take out the pins so your milage may vary. The second thing is that the metal plunger tube has a wider inner diameter than the original so your plunger tube air seal might suffer a bit. In the end, I really liked the metal priming rod and catch. The priming on higher spring loads is much smoother and consistent than on my half broken priming rod. However, I think it is best to take care of your blaster and strengthen your original priming rod than to buy this kit immediately. It has a couple compatibility and is pretty expensive.
