Description
Anyone who has run a mil-spec AR trigger knows the feeling: a mushy pull, some grit, and a break that never quite lands where you expect. The Timney Calvin Elite fixes all of that in a single self-contained module you can drop into your lower in a matter of minutes. It is factory tuned to a clean 1.5 lb pull with zero creep, and it pairs that light break with a dependable 5 lb hammer spring so ignition stays consistent round after round.
Named after Timney's design lead Calvin Motley, this trigger is built to a higher standard than most aftermarket units on the market. The wear components are cut from A2 tool steel, heat-treated to Rockwell 58 and finished with a Teflon-nickel coating, all housed in a lightweight CNC-machined 6061-T6 aluminum shell. Every unit is tested and calibrated by hand before it ships, which is a big part of why the reset feels so fast and tactile. Folks who have compared it against enhanced stock groups and JP spring kits regularly rank it near the top for feel, crispness, and that near-instant reset.
What Sets the Calvin Elite Apart
The headline feature is the shoe system. This trigger ships with four interchangeable red shoes: curved, flat, heeled, and knurled. Each one adjusts for length of pull, cast, and height, so you can position the face exactly where your finger naturally falls. That level of tuning is rare in a drop-in unit and lets you set up the same trigger differently for a bench build versus a rifle you run with gloves.
Getting the Calvin Elite Into Your Rifle
Installation is genuinely simple. Punch out your factory hammer and trigger pins, seat the module, and reinstall the pins. The proprietary design locks everything down and eliminates pin walkout, so anti-walk pins are not required. It fits mil-spec AR-15 and M4 lowers built for small .156-inch pins and is ready to shoot straight out of the box with no fitting needed.

Frequently Asked Questions
Is the Timney Calvin Elite trigger a true drop-in, or does it need fitting?
It is a fully self-contained drop-in module that installs in your existing lower with no gunsmithing or fitting. You punch out your factory hammer and trigger pins, seat the unit, and reinstall the pins. Most people have it done in under ten minutes with basic tools.
Will this Calvin Elite fit my AR-15?
It is built for mil-spec AR-15 and M4 lowers that use small .156-inch trigger pins. Before ordering, confirm your lower runs small pins rather than large pins. It works across a wide range of standard mil-spec builds.
Do I need anti-walk pins with the Calvin Elite?
No. The trigger uses your rifle's original hammer and trigger pins, and the proprietary design locks everything in place to prevent pin walkout. Once you tighten the internal locking screws under the hammer spring legs during install, anti-walk pins are not needed.
What are the four included shoes for?
The Calvin Elite ships with curved, flat, heeled, and knurled red shoes so you can pick the profile that suits your shooting. Each shoe adjusts for length of pull, cast, and height, letting you place the trigger face exactly where your finger sits. It is one of the most customizable feels you can get in a drop-in unit.
