Cylinder Upgrade advice needed

[Aj698]

Hi,

 

Like most newbies I've fallen down the inevitable tinkering rabbit hole 🤣! 

 

After the original upgrade advice of Hop rubber, nub and barrel I've swapped the hopchamber with great effect on my Specna H03.

 

Now dipping toe into the gearbox.... any advice on  cylinder upgrades, piston, piston heand and nozzle.  Trying to head around cylinder/barrel ratios with is "fun".

 

Running tightbore 6.02 363mm barrel.

 

Any pointers/advice welcome.

 

Thanks in advance

What's your current cylinder?  What's your spring and FPS? Might not be any reason to change anything, just because you can doesn't mean you should.  🙂

 

Good job for actually thinking about the cylinder to inner barrel ratio though, generally for a 363mm you want a 3/4 or 4/5

There are many good guides out there, this is one for example.  But best to ask us on these forums as we know best!

 

Thera er many videos on Youtube.  Get investigating!

Thanks for the response 👍🏻 

 

Current cylinder is the stock specna.  Not taken gearbox it apart or opened yet..  

 

Upgrade the M90 spring to ASG Milspec M105.  Hitting about 290FPS mark using .28's  

 

Looking to achieve better consistency and accuracy than FPS.

 

Thanks
