Stage 1 Upgrade - Tokyo Marui M4/416/MK18/URG-I Recoil Shock Brand_Airsofteire B-31S & B-31LStage 1 upgrade is suitable for Tokyo Marui M4 416 SCAR MK18 URG I Recoil Shock (NGRS) models. Completed by our skilled technicians, this Stage 1 upgrade replaces the factory trigger contacts with an advanced electronically controlled trigger unit from Gate and also bumps the power from approx 290fps to 320fps with a 0. 2g BB. The result is increased power and range, a marginal increase in rate of fire and a dramatic improvement in trigger response,
