VFC Molla M100 M100 spring vega force company

Born from the collaboration with a company for 30 years leader in the D100 spring it is made of steel industry Pre-hardened variable pitch.

The abbreviation stands 100 the speed in m / s reached by bullets from 0,20gr.

90 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).
Of course with shorter or longer barrel the performance will decrease or increase, therefore the calibration will be harder or softer

PIRANI SPRING TOP 120

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

PIRANI SPRING TOP 95

Springs made in Italy, with ground and self-centering support surface, spring force identification color. Anti-corrosion treatment, variable pitch spring. Made with pre-hardened steel. The springs were tested on a modified VFC M4 with two bearings, normal stroke, 270mm barrel, exhaust hop up and 0,20gr pellets, giving the values expressed by the spring

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.
