PVP spring specific for use with LiPo 7.4V battery and energy <1J. Given the nature of the platform, the use of energy <1J is directly connected to the use of 7.4V LiPo batteries to avoid hang-ups in the piston stroke with this specific spring.

Platform UMAREX/VFC MP7 AEG gen1/gen2 TopMax

Spring RCS Top Max

The central stabilization narrowing allows the spring to maintain a more linear and rectilinear position inside the air unit, minimizing lateral displacements and maximizing the life span of the spring, moreover the constant performance of the RCS spring allows to obtain a firmer shot. The RCS springs specific to TopMax Elaborazioni are individually tested during production to guarantee punctually the value expressed in m / s.

The 120 m / s FPS spring has been calibrated on 363 mm barrels and gearbox with type D cylinder (for rods from 301 to 400 mm)

Guarder SP120 Spring

Harmonic steel spring ideal for high speed preparations

The spring has coils with variable pitch in the central area and in that in contact with the spring guide and undergoes a process of grinding the two ends which guarantees optimal performance in the compression phase.

PIRANI SPRING TOP 105

Molle made in Italy, con superficie di appoggio rettificata ed autocentrante, colorazione identificativa forza molla. Trattamento anticorrosione, molla a passo variabile. Costruita con acciaio pretemprato. Le molle sono state testate su VFC M4 modiifcato con due cuscinetti, corsa normale, canna da 270mm, hop up scarico e pallini da 0,20gr, dando i valori espressi dalla molla

PIRANI SPRING TOP 110

Springs made in Italy, with rectified and self-centering support surface, identifying spring force color. Anti-corrosion treatment, spring with variable pitch. Built with pre-hardened steel. The springs have been tested on VFC M4 modified with two bearings, normal stroke, 270mm barrel, hop up and 0.20gr pellets, giving the values expressed by the spring

110 m/s FPS spring has been calibrated on 363 mm inner barrel and gearbox with type D cylinder (for barrels from 301 to 400 mm).
