Micro-Polished Surface Resists Wear & Carbon Build-Up

Precision-machined, stainless steel piston is heat treated for hardness to maintain critical tolerances, resist wear, and help prevent rounding of the gas grooves for extended service life. Micro-polished surface reduces friction and resist carbon build-up, requiring less frequent cleaning.
