Description

Sadlak M14 TiN coated NM gas piston. Sadlak precision pistons are made to the exact GI specifications with all critical dimensio with groovens individually inspected. The 420 stainless material and heat-treating operations are both certified to assure quality. The pistons have a highly polished surfaced using a non-contact electro-polishing method that maintains tolerance on the critical diameter and does not “round–over” the edges on the grooves. The pistons are then hard coated with a gold colored Titanium Nitride (TiN) finish. This coating, often used on machine cutting tools, helps reduce galling and pitting and holds up better to the high heat and abrasiveness of gunpowder and primers. The resulting effect is a smoother action an improved life of the piston and cylinder. This piston is grooved to reduce gas system recoil and increase "dwell time" in the gas system.

Recommended for use with heavier ammo (although most users have no problem with standard M80 ball).
