stti

Spring Time Taiwan Inc uses the STTI brand for gas and CO2 airsoft replicas, magazines and replacement components. The catalogue covers blowback and non-blowback sidearms, CO2-powered variants and parts associated with their gas-delivery, loading and hop-up systems. A complete replica, its magazine and an internal replacement part each require a separate compatibility check.

Gas and CO2 models use different propellant containers, valves and pressure arrangements. Blowback and non-blowback actions also differ in nozzle, slide and magazine function. Internal parts such as nozzles, sears and hop-up chambers are tied to the dimensions and geometry of a stated model; their category name alone does not establish that they can be exchanged between STTI variants.

Before choosing an STTI product, confirm the exact replica model, action type and propellant. For a magazine or replacement part, compare valve type, nozzle dimensions, sear geometry, hop-up arrangement and product code with the existing component. Use the individual listing for variant-specific fitment and do not infer compatibility from a similar external shape.
