T8 Enhanced 70 Degree Piston Head - Sig P320 / M17 / M18 Voltage_11.1V The Caiman helmet system isThe T8 piston head serves as a gas flow efficiency enhancement for the Sig Air pistol series. It significantly improves air seal tightness and overall gas efficiency between the pistol and the magazine. Featuring a Deep V indent design, the piston head ensures enhanced airtightness during gas expansion, resulting in a sonic effect phenomenon as the gas contracts while the piston reshapes itself, thereby delivering a more stable gas output performance.
