EvoSpray is now offering an upgraded tip (harder material = less scratches = less leaks and longer life)
We start with a harder material than the others and then case harden and temper it when we finish the machine work..
This sale is for 1 mix chamber
This equals a better product for both me and you.
This is the same as an AR4747.
We currently use these chambers in our own guns and love them.
Why would you pay so much more for the "brand" name part?
