K-80 ACS

K-80 ACS. All Clay Sports

The ACS puts our founder Ludwig Krieghff's axiom "you shoot with the barrel, you hit with the stock" into practice. The ACS buttstock has a #6 Adjustable Parallel comb that puts the shooter's eye directly over the rib. The ACS rib is raised high to facilitate a "heads-up" mount with adjustable front rib wheel to adjust the POI from 60/40 all the way to 100% over. The ACS combo is the perfect solution for Trap shooters with a combination of an over/under barrel and an unsingle barrel allowing the shooter to shoot singles trap, doubles trap and even Sporting Clays or Skeet. The ACS is the complete "All Competition Sporting" shotgun.

Receiver finish options
  • Nickel plated receiver finish.  Nickel is our most durable finish option for a receiver.  The nickel resists corrosion and provides a great finish for hard use.  Nickel is not available in conjunction with Gold Plating.
  • Blued receiver finish.  The Krieghoff Blued finish is a deep black color and provides a traditional look to a modern gun.
  • Nitrated receiver finish.  A nitrated finish is common on heavily engraved guns, especially with gold inlays and custom engravings. The nitrated finish provides a coin-grey finish and is easy to maintain.
  • Color case hardened finish.  Color case hardening is one of the original gun finishes available for fine shotguns.  With variations of blues, grays and straw colors the process makes a unique finish each time. Less durable than Nickel or Nitrated finishes we finalize the finish with a clear lacquer to provide an additional layer of protection.
Lock finish options
    • Internal lock parts nickel plated
    • Internal lock parts gold plated, triggers not included and must be specified
    • Titanium trigger (including trigger group), gold plated
