The Timney Calvin Elite is a premium two-stage competition trigger for AR-15 rifles, designed by Timney Triggers in collaboration with professional shooter Calvin Sims. This drop-in trigger is recognized in the world of precision shooting competition and tactical training for the exceptional quality of its break, its short reset and its perfectly studied progressive engagement.
History and Development of the Timney Calvin Elite
Timney Triggers, founded in 1946 by Allen Timney in Phoenix, Arizona, has established itself as one of the most respected manufacturers of replacement triggers in the United States. Over the decades, the company has expanded its initial line of bolt-action shotguns (Mauser, Remington 700) to cover almost all modern platforms, including the AR-15, AR-10, Ruger 10/22 and many European sports rifles.
The Calvin Elite was born out of a collaboration with Calvin Sims, a longtime gunnery instructor and former member of the U.S. Navy’s Sniper Team. The goal of the project was to create a two-stage trigger that could meet the most stringent requirements of sport precision shooting (PRS, NRL) while remaining reliable for tactical use. Launched in the late 2010s, the Calvin Elite quickly established itself as one of the best two-stroke drop-in triggers available on the AR-15 market.

Operation and Technical Particularities
The Calvin Elite is a self-contained drop-in trigger: all components (hammer, trigger, springs, sear) are pre-assembled inside a machined aluminum case, which guarantees a perfect geometry that is identical from one unit to another. Installation is limited to removing the original trigger and inserting the Calvin Elite module, secured by the two standard AR-15 pins.
The two-stage operation offers two distinct phases when pressing the trigger tail. The first step, about 1 lb, requires a light linear pressure that brings the trigger to a hard, well-defined wall. The second stroke, about 1.5 lbs, triggers the shot with an extremely clean break, with no creep or noticeable overtravel. This architecture allows the shooter to confidently take the wall, stabilize their aim, and then fire at the precise moment they want. The reset, very short and tactile, is particularly appreciated in rapid chain fire.
Variants and Versions
The Calvin Elite range is mainly available according to the shape of the trigger tail. The Straight version is the most popular with PRS competitors because it ensures a constant touch regardless of the angle of attack of the finger. The Curved version uses the classic shape of mil-spec triggers and will be better suited to shooters used to the traditional AR-15 profile. Timney also offers specific configurations for AR-10 / SR-25 (.308 Winchester chambers, 6.5 Creedmoor) with matching diameter pins, as well as a “Calvin Elite Skeletonized” version offering a lightened and perforated trigger tail.
Users and Areas of Application
The Calvin Elite is widely used in precision sport shooting, especially in the American PRS (Precision Rifle Series) and NRL (National Rifle League) disciplines, as well as in equivalent European competitions (CRPS, long-range shooting). It is also used in the rifles of many civilian instructors and demanding recreational shooters. In tactical use, several specialized American police units and private contractors have adopted it for their service rifles because of its reliability, its constant behavior over time and the lifetime warranty offered by the manufacturer.
Civil Possession in Switzerland
In Switzerland, the Timney Calvin Elite is available from gunsmiths specializing in AR-15 and AR-10 accessories. The trigger itself is not considered a weapon within the meaning of the Federal Weapons Act (Firearms Act): it is an internal component. Its purchase therefore does not require a specific permit. On the other hand, it is intended to be installed on a semi-automatic rifle of military origin (AR-15, AR-10), a weapon which, since the revision of the LArm of 2019, requires an exceptional cantonal authorization for acquisition, unless there is special justification (licensed sports shooter, collector, professional). Installation by an approved gunsmith is recommended to preserve the warranty and ensure the proper functioning of the weapon.
Conclusion
The Timney Calvin Elite has established itself as an absolute benchmark among two-stage drop-in triggers for AR-15. Combining watchmaking work on the feeling of a break, rock-solid reliability and a lifetime warranty, it represents a long-lasting investment for the serious competitor as well as for the demanding sniper. While the price puts it in the premium segment, its consistent behavior from unit to unit and longevity make it a rational choice for those looking to fully exploit the precision potential of their AR platform.
