500 Series
Clark/Ruger .22 Semi-Auto Match Pistol Barrels

500 Series barrels fit the Ruger MK I, MK II, and 22/45 models. Barrels are completely turned, threaded, chambered, crowned, polished, and finished. They are made from Walther premium blanks, and are available in chrome-moly or stainless steel. They are offered with or without a replaceable, serrated-ramp, undercut, partridge, front sight. Barrel lengths offered are 5-1/2" and 6-1/4". The 6-1/4" model has a built in compensator. Installation requires lathe work.

Part 510
Clark/Ruger Match Steel Trigger

(Part CLK-510) When used in conjunction with a trigger job, this trigger allows for a sharper, crisper pull. It removes the trigger sideplay that exists with a factory trigger. It can be fitted to Mk I, Mk II, MkIII or 22/45 Ruger .22 semi-auto pistols. The trigger features a micro-adjustable overtravel stop and a wide arc so the trigger finger will not drag on the trigger guard. A sharp serrated face with a wide, flat surface allows for finer finger pressure control. Some fitting is required.

Part 515
Clark/Ruger MKI / MKII Sear Pin and Hammer Bushing Kit

(Part 515) Oversized sear pin and hammer bushing provide closer tolerances and allow for lighter, more consistent trigger job. These parts are included with all Mk I and Mk II trigger jobs.

(Part 517) Not pictured ~ Oversized Hammer Bushing and Sear Pin that we use on the Ruger 22/45 to obtain the best possible trigger job.
