This is the trigger that makes you notice how sloppy your old one was. The TriggerTech AR Diamond is the top of TriggerTech's AR-15 lineup, a fully self-contained drop-in unit that swaps into a standard mil-spec lower without any fitting or filing. It runs a short two-stage action designed to feel like a fine 1911, giving you a defined take-up and a distinct wall before a clean, glass-rod break. The heart of it is Frictionless Release Technology, which uses a free-floating roller between the sear and hammer instead of two sliding surfaces, so there's essentially no creep and the pull feels the same from the first shot to the ten-thousandth.
Most triggers get lighter by cutting engagement, which eventually chews into reliability. The Diamond doesn't play that game. Because the roller carries the load, adjusting pull weight doesn't reduce hammer strike force, so you get full-power primer hits whether you're set at 1.5 or 4.0 pounds. That matters if you run harder military or match primers and still want a feather-light break. A neat side effect of the zero-creep design is that most folks report the pull feeling about half a pound lighter than a friction-based trigger measuring the same weight.
Adjustment is refreshingly simple thanks to CLKR Technology. An accessible set screw lets you tune pull weight in 2-ounce clicks anywhere from 1.5 to 4.0 pounds with the trigger already in the rifle, so there's no tearing things apart to find your ideal setting. The Pro Curved lever splits the difference between a traditional bow and a flat face, giving your finger a natural, repeatable placement.
Internals are hardened 440C stainless steel with a 7075 anodized aluminum housing, and the external parts wear a durable PVD black finish for corrosion resistance and a long service life. It's built for precision rifle work, 3-Gun, target shooting, varmint hunting, and duty use, backed by a lifetime warranty. If you've been curious what a top-tier trigger actually feels like, this is a strong place to start.
This model is the two-stage version, built to feel like a short 1911 trigger with a defined take-up and a crisp wall before the break. TriggerTech also offers the Diamond in a single-stage configuration under a different part number, so double-check the model if you specifically want single-stage. This exact SKU (AR0-TRB-14-NNP) is the two-stage Pro Curved in black.
It's designed as a self-contained drop-in unit for standard AR-15 lowers that use mil-spec 0.154-inch trigger pins. No fitting or gunsmithing of the sear surfaces is required, though the trigger pins themselves are not included. If you're not comfortable installing and safety-checking a trigger yourself, a qualified gunsmith can handle it quickly.
The Diamond uses CLKR Technology, so you adjust pull weight with an accessible set screw while the trigger is installed in the rifle. It moves in roughly 2-ounce clicks across the full 1.5 to 4.0 pound range. Changing the weight doesn't reduce hammer force, so you keep reliable primer strikes at every setting.
No. Because the Frictionless Release Technology uses a free-floating roller to hold the load, lowering the pull weight doesn't cut into hammer strike force. You get full-power, dependable primer ignition even at the lightest 1.5-pound setting, which is why it handles harder military and match primers well.
