A fast, crisp Hi-Capa for speedsoft. The PDI 113mm barrel is the stock 5.1 length. The Guarder nozzle gives a stronger, steadier blowback. The MNA guide rod and hammer pad protect the slide and frame from hard cycling. The Laylax trigger and 5KU magwell make trigger pulls and mag changes quicker. Example build by LoadoutLab.
