Burrs? Or do you mean loose metal shavings?
There were no shavings in the top end. The sleeve was rough at the very top. There were no burrs on the bottom of the sleeve, which I found strange.
The piston does not rise as far as the top of the cylinder sleeve.
The piston in the Tower .75 goes to within .023 +/-.001 to the top of the sleeve.
The sleeve is honed after the chromium plating is electro-deposited.
In my opinion the burrs were introduced after plating.
