The T8 70 Degree Magazine Gas Route Seal/Gasket is an upgrade designed for the Sig AIR / VFC P320, M17, M18, XCarry, and P226 GBB magazine. It improves air seal tightness and gas efficiency performance, helping the platform deliver more consistent and reliable gas operation. With a 70 degree rubber hardness, the seal is firmer than standard, which supports enhanced gas flow efficiency and a more stable transfer of gas between the magazine and nozzle. The purple finish also gives the part a distinct and recognizable look.

At the heart of the design is the Mansard Roofing technique, which provides stable gas discharge and better airtight interaction between the magazine gasket and nozzle. The gasket opening is specifically shaped to create an airtight interaction between the magazine and nozzle, making it ideal for P320 Carbine Kits and other setups where gas efficiency matters. This combination of firmer rubber and thoughtful sealing geometry helps reduce gas loss, improve shot-to-shot consistency, and make better use of the gas available in the magazine.

The Gasket Route Seal is therefore an upgrade for the Sig AIR / VFC P320 and P226 Series GBB magazines. It is compatible with Sig AIR / VFC P320, M17, M18, and X-Carry GBB magazines, as well as the Sig AIR / VFC P226 and the VFC / Stark Arms SA320 GBB magazine. Whether used in a standard pistol configuration or a P320 Carbine Kit, it is intended to provide better gas performance and efficiency through improved sealing between the magazine and nozzle.
