Helps Ensure Smooth, Reliable Cycling & Long Service Life
Precision-ground replacement gas piston is machined from high-grade 420 stainless steel to mil-spec dimensions for proper fit in your M14, M1A, or other mil-spec M14 clone. Heat treated, hardened surface helps maintain critical tolerances and minimizes gas groove wear for a long service life. Polished finish reduces friction to help promote reliable cycling, and resists carbon fouling for enhanced corrosion resistance and less frequent cleaning.
