ARES Amoeba Striker CPSB Tuning Cylinder Kit

ARES Amoeba Striker sniper rifle, improved and equipped with reinforced parts, a tuning cylinder package. The package includes the cylinder with all the necessary parts, and this can therefore be installed practically directly (of course lubricated) in the weapon. The spring in the package is SP450, i.e., approximately M135-level. Of course, stronger springs are also available, and they can be installed directly in this cylinder. Most of the parts in the package are steel, but the piston is a hybrid model, i.e. the tuning part is steel, the rest of the piston is aluminum to reduce weight.

CPSB (Compact Power Spring Bolt)

CPSB is a tuning kit developed by ARES for their Striker rifle. The kit is unique in that it has a short barrel length, as the name suggests. This allows for a longer inner barrel and the right position for the magazine, without any loss of power.
