Not much maintenance is needed. When I swapped the stocks, I took a good hard look at the mechanics of the k-80. I wanted no part of that. I schedule an annual service with Krieghoff while they have their gunsmiths at the Grand. Krieghoff recommends the annual service be performed every 20,000 to 30,000 rounds or 2 to 3 years.
Per Krieghoff International.
Annual Service
During your Annual Service, our highly-skilled gunsmiths will completely disassemble your firearm, replace firing pins and springs, inspect for repair, clean and lubricate, and adjust to factory specifications. This service includes checking the gun for headspace, overcock, proper tolerances of sears, ejectors and hammers and complete disassembly and replacement of springs as needed throughout the receiver and forend iron. All parts are inspected for wear and minor trigger and timing adjustments are made if needed. The gun is cleaned and lubed. The barrel is tightened to the actions when possible. Replacement of broken or badly worn parts is available, at additional cost. The K-80 Annual Service is $295.00 (1 or 2 Barrels); The K-32 Annual Service is $375.00 ( 1 or 2 Barrels); The KX-5 & KX-6 Annual Service is $175.00 and The KS-5 Annual Service is $195.00. Annual services require the entire gun be sent in to ensure complete and guaranteed service. Annual service prices slightly higher for 3 or more barrel sets.
