The MASV2/V3 tappet-plate return spring is a spare designed for AEG platforms using V2 and V3 gearboxes. Manufactured in cooperation with industry specialists, it is made from oil-tempered carbon steel wire with silicon and chromium additions (EN10270-2 specification). Immediately after forming each spring is oven-stabilised at 400 °C for 30 minutes to optimise fatigue resistance and service life.

Intended for routine maintenance, overhauls and tuning kits, this spring supports consistent tappet-plate behaviour and contributes to reliable feeding timing. Full Italian production ensures strict quality control and traceability across the manufacturing process.

Concrete benefits: industrial-grade spare, longer life compared to non-stabilised springs, compatibility with Marui-style V2/V3 gearboxes and reduced risk of long-term deformation.

Warnings & maintenance

Do not tamper: do not alter, stretch or reshape the spring; unauthorised modifications can impair gearbox function and cause malfunctions.

Installation: gearbox disassembly skills are required; if unsure, have a qualified technician perform the replacement to avoid damage to gears, piston or tappet-plate.

Storage: keep the spare dry and in a temperate environment; protect from moisture and corrosive agents that could affect surface treatment.

Post-installation checks: after fitting check timing, perform low-rate testing and inspect for unusual wear; use appropriate lubricants for internal parts.

Safety: wear eye protection during bench tests and assembly; keep out of reach of children.
