Overview
The ASG Ultimate Upgrade Series MP5 Steel Trigger is a reinforced replacement trigger for MP5 and Mod5 series airsoft AEGs. It actuates the trigger switch that completes the firing circuit, so keeping this part crisp is key to reliable trigger response.
Why upgrade
Standard MP5 triggers are commonly moulded plastic or soft metal that wears and flexes with use, leading to a spongy or unreliable pull. Machined from reinforced steel, the Ultimate trigger resists deformation and keeps engagement sharp even under heavy skirmish use.
Fitment and compatibility
The MP5 series uses its own trigger shape, distinct from the M4 pattern. This trigger fits MP5 and Mod5 replicas from ICS, Umarex, Classic Army, SRC, JG, CYMA, Tokyo Marui, Echo1, G&G and most compatible models. It is mechanical only and works with your existing switch and wiring.
Fitting and servicing
Installation requires opening the gearbox, so it is best done alongside a service or rewire. Our airsoft repair and servicing team in Kent can handle it, or browse more airsoft accessories and parts for your project.
