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. 

PIRANI SPRING BASIC 95

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
