Specna Arms springs are made using the highest quality steel wire.
They are therefore durable and carefully finished, as they have polished ends.
The spring features 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 a great choice for any airsoft player looking to achieve a precisely defined muzzle velocity, ideal for tuning all types of AEG replicas.
