New Nozzle and Value M9a1

[Ragnaraz]

I recently bought the Dynamic Precision CNC nozzle and the power up valve for inside it for my TM Samurai Edge.

Got a Dyna piston head on the way too, but I have seen a few of those come with a new valve spring for in the nozzle. DP actually do an enhanced spring for it as well.

 

My question is, do I need to replace that spring too? I have tried looking around and I cannot find an answer for that question anywhere, and could anyone tell me what that spring would even do? I ask because I don't think my version came with the spring.

 

If possible I'd like all my parts together cause I do not want to have to take the slide to pieces again if I can help it. I can thankfully change the barrel/hop and that stuff without having to remove the piston rail and all that jazz.

 

Cheers in advance!
