Accurizing Kits

A factory Ruger Mark IV trigger works, but it is built to a price. An accurizing kit replaces the fire control parts with precision-machined components for a lighter, crisper break, less overtravel and a faster reset. As an authorized dealer for Volquartsen, TandemKross and Tactical Solutions, we carry the kits competitive rimfire shooters trust for the Mark IV and 22/45, plus the bolts, grips and controls to finish the build.

Choosing an Accurizing Kit

Accurizing kit or competition kit

An accurizing kit focuses on the trigger: a cleaner break, less creep and a faster reset. A competition kit goes further for shooters building a dedicated race gun. Start with the accurizing kit if you want the biggest improvement for the money.

With or without a trigger

Kits are offered with a trigger in red, gold or black, or without a trigger if you already run an aftermarket blade like the Volquartsen 19.22 or TandemKross Victory.

Pair it with a bolt

A crisp trigger shows its best with a precise lockup. The Volquartsen Competition Bolt and TandemKross Krossfire Bolt are the natural next step.

Finish the pistol

Round out the build with a pistol barrel, a compensator and a red dot sight.

Accurizing Kit FAQ

Will an accurizing kit fit my Ruger 22/45?

Yes. The Mark IV accurizing kits we carry are listed for both the Mark IV and the 22/45. Check the fitment notes on each listing before ordering.

Can I install an accurizing kit myself?

Many shooters do with basic tools and the manufacturer's instructions. If you are not comfortable working on fire control parts, have a qualified gunsmith install it, and always function check the pistol afterward.

Should I buy the kit with or without a trigger?

Choose the kit with a trigger if you are running the factory trigger. If you already have an aftermarket trigger you like, the no-trigger version saves money.
