Specna Arms SA-K02 ONE Kestrel ETU AEG - Black

The housing of the SA-K02 is mainly made of a zinc-aluminum alloy, screws, pins and belt holder are made of steel. The stock and pistol grip are made of polymer plastic. The AEG uses the Enter & Convert™ quick spring change system. This allows for quick and efficient adjustment of the replica's performance to the expected conditions on the field, without the need for access to a workshop or a set of special tools - after removing the gearbox, the spring change itself takes literally seconds.

The improved version features a number of new, reinforced parts such as:

- reinforced steel gears
- steel spring guide
- lightweight polymer piston
- sealed aluminum piston head
- metal cylinder head
- sealed metal nozzle
