Description The titanium AK gas piston is a lightweight replacement component designed for standard AK-pattern rifles. Constructed from Grade 5 titanium, the piston measures approximately 6.358 inches (161.5 mm) in length and weighs about 1.47 ounces (42 grams), making it roughly half the weight of a conventional steel piston. The exterior is finished with a diamond-like carbon (DLC) coating, providing a smooth surface and a silver coloration. This piston is intended for installation in the bolt carrier assembly of compatible AK platforms where a titanium upgrade is desired. The piston design allows adjustment by rotating it within the carrier to modify the internal gas chamber volume. This mechanical adjustment changes the amount of gas pressure directed to the bolt carrier group, enabling control of operating characteristics such as recoil impulse. The titanium construction provides high strength-to-weight ratio and resistance to temperature variation, while the DLC surface treatment helps reduce friction and wear between moving components. The combination of these materials and coatings contributes to extended durability under repeated cycling. This AK gas piston is in new condition. The item consists solely of the titanium piston with DLC coating and does not include additional accessories or packaging beyond the component itself. Dimensions and material specifications are as stated, with the part finished in a silver tone characteristic of coated titanium Specifications: Material: Titanium Grade 5 Coating: DLC Color: Silver Height: 6.358″(161.5mm) Weight: 1.47oz (42dr)
