Tandemkross Essential Maintenance Kit for Ruger Mark Series & 22/45

The Tandemkross Essential Maintenance Kit is an aftermarket replacement and upgrade parts package designed for the Ruger Mark Series of .22 LR pistols, including the Mark I, Mark II, Mark III, Mark IV, and 22/45 models. It bundles the most commonly lost, worn, or broken small parts into a single set so a shooter always has spares on hand for routine service and range-day repairs.

Built from stainless steel and titanium components, the kit combines reliability spares with select performance upgrades. Included is a Rebound Spring 5-Pack to keep the slide's cycling action consistent, Tandemkross's Eagle's Talon Extractor for reliable case extraction, the Fire Starter Titanium Firing Pin - a lightweight drop-in that is lighter than the factory firing pin for reduced lock time - plus an Extractor Spring and Plunger set to complete the extractor rebuild.

Designed for long-lasting reliability and built as a direct fit for Ruger Mark-pattern pistols, this maintenance combo is a smart bench-stock addition for anyone who shoots and services their Ruger MK series pistol regularly.
