The MK3 pairs a heavy-profile, fluted 24" barrel with a CIP-marked .338 Lapua Magnum chamber and a 1:10 twist, delivering a purpose-built configuration for the cartridge. The barrel is threaded and fitted with a muzzle brake.
Its KRG-branded aluminum chassis brings adjustability and rigidity, with an adjustable cheekpiece and adjustable butt, a skeletonized layout, and a vertical pistol grip. A Kick-Eez recoil pad and a 13.25" length of pull round out the fit and interface.
The action uses a spiral-fluted bolt with an oversized bolt knob for confident cycling. Up top, the receiver carries a Picatinny scope rail, and the extended underside accessory rail/spigot on the forend adds mounting real estate. Accessory rails are present.
Feeding is via a detachable box magazine system marked for .338 CIP, with a maximum capacity of 5+1. This rifle includes two steel 5-round magazines. It is an early low-serial example and a seldom-seen entry in the PWS lineup.
