Jerry provided these photos of the first 2500X action off the production line. Jerry notes that: “The only difference with the final production version is that the body will be melonited on the inside for super-slick operation and the outside will still be polished for great looks”.

Stiller 2500X Rimfire Action Features

• Dual rear locking lugs symmetric about the horizontal centerline.
• Super tight tolerances on all fitted parts.
• Firing pin design easily unscrews.
• 6 o’clock or 12 o’clock firing pin. The other pin acts as a guide to eliminate any off-axis canting that can impair ignition and cause flyers.
• Cocking piece controlled by a shroud so it is always centered in the trigger and cannot rub.
• Easy loading ramp design similar to the Anschutz.
• Entrance cams in the body.
• Beveled loading port
• Four #8 screw holes for scope mounts, plus two #6 screwholes (in between) also reamed for .125 pins. That way a long one-piece mount or just front-only will both be accommodated.
• Threaded bolt handle so that any available knob will work. Stiller offers three knob types.

State-of-the-Art Machining Technologies Used to Make 2500X Actions
A multi-step process is employed to deliver precision tolerances on every 2500X action. The process begins with a drilled, undersize hole. Then the body is cut and heat-treated/stress-relieved with oversize outside diameter (OD). The Inside diameter hole is wire-EDM finished after heat-treating for optimal sizing and straightness. Next the OD is ground to size and the action face and threads are machined. The action is finally engraved, hand-finished, and melonited on the inside (unless the customer specifies a non-melonited version). Individual parts receive special attention — the extractors are wire-EDM cut, and the bolt lugs are factory-lapped with special devices to load the lugs as they would be when fired.
