SPECNA ARMS M140

M140 SPRING 
SPECNA ARMS 

specna arms springs are made with the highest quality steel wire.
They are therefore durable and carefully finished, as they have polished ends.
The spring has an irregular pitch of the coils, which results in a longer service life of the system, significantly reducing the "bumping" effect of the spring.
Specna arms springs are an excellent choice for any airsoft player who wishes to achieve a precisely defined initial velocity, ideal for tuning all types of aeg replicas.
