Timney Triggers Made with State-of-the-Art Automated Machinery

Editor — Wed, 07 Oct 2015 11:00:37 +0000

For years, Timney triggers have been popular drop-in upgrades for hunting rifles, rimfire rifles, and AR platform rifles. To meet the demand for its many trigger products, Timney Triggers has expanded its operation, adding state-of-the-art CNC machines and other high-end, automated equipment. A far cry from the dank gun factories of the 1950s and 1960s, Timney’s Arizona production center now resembles the squeaky-clean, ultra-modern facilities where electronics are assembled.

Today’s Timney factory is all about computerized automation. Timney Triggers’ owner John Vehr states that it would take 60 or more trained machinists and metal-workers to produce as many triggers as can Timney’s modern machines. Timney does employ two dozen workers, but they are assigned tasks that the computerized machines can’t do as well or better.

If you want to see how Timney triggers are made this days, check out Tom McHale’s recent account of his visit to the Timney Factory in Scottsdale, Arizona. McHale explains how the triggers are designed and fabricated, and 20 high-rez photos illustrate the production process and machinery.

New Stiller 2500X Rimfire Action Revealed — Goes on Sale This Fall

Editor — Wed, 21 Aug 2013 14:06:48 +0000

Jerry Stiller of Stiller Precision Firearms has revealed the final pre-production versions of his new 2500X rear lock-up rimfire action. Jerry reports: “I have eight of them as prototypes that have been sent to our best smiths to build on and test. As soon as we hear back (in a month or so?), we will start the next run of 100. There will be plenty to go around and should be available this fall for next year’s builds. Cost will be competitive, estimated $1249.00 retail”. Notably, this new action features a convertible 6 o’clock or 12 o’clock firing pin, giving the owner the choice of his preferred configuration. The trigger hanger can also be reversed for a 0.030 change in pin fall.

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.

Timney Offers New Drop-In Trigger for AR10-Class Rifles

Editor — Fri, 09 Nov 2007 16:41:10 +0000

Timney Triggers now offers a true drop-in trigger for the AR10 rifle platform, similar to Timney’s successful drop-in trigger for the AR15. The new AR-10 trigger is a self-contained, 100% drop-in unit that can be easily owner-installed (no professional gunsmithing required). The new trigger is a single-stage design with pull weight factory-set at 4 pounds. The trigger module installs using your rifle’s original hammer and trigger cross-pins. The MSRP is $234.95, but we expect the trigger to be available for $210 or so from other vendors.

The new trigger is solidly built and precision-machined. The housing is lightweight, 6061 T6 aluminum alloy, anodized for durability. The hammer is EDM-machined from S7 tool steel for superior hardness and impact resistence, and the hammer is Teflon + Nickel coated to provide greater lubricity and a smooth pull. Other components are EDM-cut from A2 tool steel, then heat treated to Rc 56-60 for longer service life. For more information on Timney Triggers, call (866) 484-6639, or visit TimneyTriggers.com.
