TM Scar H upgrade nozzle

[Sneaky]

Hi all,  is this thing like gold dust as I cannot find what I am looked for.  I'm just working on my list of parts to buy and I have order parts from eagle6.  I always tend to source the parts I want before buying the aeg - Will do the work myself if and when needed.

 

I'm after thiis but everywhere I look does not have it in stock or is discontinued:

Which then means that this is my only option for the silly price!

Anyone who has the Firefly nozzle, it is really that good?  I have looked at SHS, but there nozzle is 28mm long - compared to the stock one which is ?

 

Any information on the above would be great!

 

Thanks all.
