Lightweight hybrid piston ZERO for L96, MB01,05,06, SW M24, M99 sniper rifles

Reinforced piston for your airsoft sniper rifle. For maximum performance and durability. The hybrid piston is made of three different materials: Light aluminum body POM ring for better sliding in the cylinder Catch back end part made of stainless steel. Compared to the previous version, the piston was completely redesigned. Rubber pad now exceeds larger area with the back-pressure holes, stainless steel part is shorter, piston is more lightweight. This reduce the weight by a quarter over the previous generation. And lower weight means higher performance. The groove below the sealing ring is shallower with a modified shape, reducing the risk of head deformation due to impact. Improvements have also been made to the sliding POM piston rings for longer life of the front of the piston. They were slightly enlarged so that the metal parts did not touch cylinder and had a smoother surface. SPECIFICATIONS: The piston is made by CNC machining from light, but durable aluminum alloy 6061-T6 (Dural) with a high-quality anodized finish. The piston catch is made of stainless steel. The piston has two sliding polyacetal (POM) rings. The piston head has an back-pressure system with O-ring (O-ring expands and seals better when shotting). The enlarged inner piston diameter allows you (and we recommend) to insert a stronger 9mm spring upgrade. Dimensions: lenght - 117mm, outer diameter - 19,8mm, inner diameter - 13,5mm Weight: 30g APPLICATION: Maruzen APS 2, EX , Type96 Well MB01, MB04, MB05, MB06, MB08, MB13, MB14 Snow Wolf (SW) M24 SW-04 , M99 SAG E&C L96 Specna Arms L96
