OFF-TRACK: Ruger 1022 Buildup, Making a Match Grade .22!


A gun's trigger has a huge effect on accuracy.  A trigger with a smooth take up and a crisp, well defined and fairly light break can make a big difference in accuracy as the perceived feel helps the shooter fire the rifle without imparting shakes or flinches into the gun.  A match trigger is a high precision part.  How the trigger is modified is also critical for safety.  Indiscriminant messing around with the trigger can cause the gun to go full auto or have an accidental discharge if the gun is shaken or dropped.  Therefore you really have to know what you are doing when modifying a trigger.  The 1022 is a low cost production rifle and its trigger leaves a lot to be desired.  The trigger is gritty, has a lot of play and has a lot of creep. Upgrading it makes a huge difference.  Trigger upgrades can be accomplished by having a competent gunsmith mess with your trigger's internals or high quality close tolerance parts from companies like Volquartsen can be installed in your trigger.  We decided to just get Volquartsen's entire trigger assembly instead.  When you consider what you are getting it is only slightly more expensive than adding the internals to your stock trigger.  The Volquartsen trigger group is housed in this close tolerance CNC machined aircraft aluminum billet housing. This replaces the stock pot metal part. 
The heart of the Volquartsen trigger is the action group.  Volquartsen re-engineers these parts with their own parts, close tolerance EDM machined from A2 tool steel and hardened RC 58-60 for long life.  This is a significant upgrade from the stamped steel stock stuff.  The notches on the hammer and sear as well as the motion ratios of the trigger and disconnector have all been engineered to give an excellent but not hair trigger.  The Volquartsen trigger is also very solid feeling, not loose and rattley like the stock Ruger part.  This gives the trigger the feel of a high quality expensive custom rifle.
The extractor is very important in a semi automatic rifle as it controls a lot of how reliably the spent cartridge case can be ejected from the chamber after firing. It is also a high wear and high stress part. The Volquartsen extractor is EDM machined from A2 tool steel and hardened to RC 58-60.  This is way stronger and longer wearing than the stock extractor.  The Volquartsen extractor also has a sharp negative profile to better engage the rim of the .22 case.  A high quality Wolf extractor spring is much more fatigue resistant than stock.  Since our Green Mountain barrel has a tight chamber, a well tuned extractor is critical for reliable semi automatic fire with accuracy.
Our trigger group uses this automatic bolt release.  This means that when the bolt is locked back, all you have to do is pull the bolt's charging handle rearward and release it to chamber a round.  The stock part has to be pressed to release the bolt.  This simplifies operation.
The stock Ruger magazine release is a recessed square button which makes it hard to find by feel.  The Volquartsen part is huge and easy to operate quickly by feel.
The Volquartsen hammer strut is the spring that powers the hammer hitting the firing pin.  The Volquartsen hammer is light and low mass, to reduce lock time, which is the time that is taken between when the trigger is pulled to the time that the cartridge is fired.  Reducing lock time increases accuracy. With lighter parts the firing force can be reduced so the gun can have less internal fiction as well as less wear and tear.  The strut is polished for smooth operation and uses a super high quality reduced force Wolfe spring.
