The bolt shroud is located in the body by a pin that perfectly centers the cocking piece in the trigger such that good consistent contact is made to the trigger sear. The firing pin is guided internally in the bolt such that the only contact points are the pin in the front and a small section in the rear near the cocking piece. No other action completely controls all the angular misalignment and rubbing points like this one does. The ignition system is a culmination of all the designs out there with all their issues fixed. All the internal parts are made in similar fashions. It also gives the attractive black lettering on the perfectly ground surface. They are then re-ground again and the OD is held within 0.001 diameter, straightness and roundness. The parts then go to Melonite to surface harden, make slick and black. The threads and face are then put in and engraved. We then heat treat the parts, stress relieve them and then GRIND the OD to the ID. At that point some of the machining happens.
We gun drill, pull ream with barrel type bore reamers and OD turn the blanks to an oversize dimension.
We start with the finest stress relieved 416R steel. The processes and steps that occur in the manufacture of these are bordering on being ridiculous. No stone was left unturned for this line of actions. The Stiller Precision Rimfire Actions 2500X actions are Stiller Precision Rimfire’s attempt at perfection.
