TriggerTech built the Diamond to satisfy the folks who chase the smallest groups and the fastest splits, and it shows the second you dry fire one. The heart of it is Frictionless Release Technology, which swaps the usual sliding, scraping engagement surfaces for a free-rolling design. That means the pull stays consistent shot after shot, and it holds up after thousands of rounds without the grit and drag that creeps into ordinary triggers over time.
This is a short two-stage action tuned to feel like a good 1911. You get a light, deliberate first stage, then a clean stop at the wall, followed by a true zero-creep break and almost no overtravel. The tactical reset comes in under 0.030 inches with a tactile mid-force snap, so quick follow-up shots feel natural. The flat shoe gives you a consistent finger placement and a straight-back pull, which is a big part of why so many owners describe the break as glass-rod crisp.
CLKR Technology lets you set the pull weight anywhere from 1.5 to 4 lbs in 2 oz increments using a single set screw, and you can do it with the unit already installed in the lower. Adjusting the weight does not change hammer force, so you still get full, dependable primer strikes even at the lightest setting. The flat-wire hammer spring keeps that hammer energy strong across the whole range, which matters if you run harder primers.
The cassette-style housing is 7075 aluminum, and the key internals are hardened 440C stainless steel for corrosion resistance and long service life. The Black version wears a PVD finish over the external stainless components for a clean, durable look. It drops into standard mil-spec .154 inch pin AR-15 lowers, and small-pin AR-10 pattern rifles will often work as well. Note that trigger pins are not included, so grab a set if you don't have spares on hand. TriggerTech backs the Diamond with a lifetime warranty.
Yes, the Diamond is a fully self-contained cassette-style unit that drops into standard mil-spec AR-15 lowers with .154 inch pins. You set the rear pin, safety, and front pin, then run a function check. Keep in mind that trigger pins are not included, so have a set ready before you start.
It's built and listed for the AR-15 platform, but it will often work in small-pin AR-10 pattern rifles that use the .154 inch pin. If you have a large-pin AR-10, it won't be a direct fit. TriggerTech makes a dedicated AR-10 Diamond if you want a guaranteed match.
The Diamond uses CLKR Technology, so you adjust pull weight in 2 oz clicks with a single set screw, ranging from 1.5 to 4 lbs. The best part is you can do it with the trigger already installed in the rifle. Changing the weight does not reduce hammer force, so you still get reliable primer strikes at the lighter settings.
The big difference is Frictionless Release Technology, which replaces sliding engagement surfaces with a rolling design for a true zero-creep break. That gives you a cleaner, more consistent pull that stays that way over thousands of rounds. The hardened 440C stainless internals and 7075 aluminum housing also hold up better in harsh conditions than typical stamped mil-spec parts.
