Hi there, new here!
I was thinking about upping my Bar 10 with a smexy new inner barrel. I hear the prometheus ones are nice for the cash. Although I did notice "Suitable for Marui Type 89 / VSR-10 ( PSS10 Air Seal Chamber Required )"

I thought the PSS10 was the laylax series name for all the vsr parts.

Now i have the stock hop up. Will this part work without buying the laylax part?

Thanks for the time and any advice :p :D
