TriggerTech built the AR-10 Diamond for people who care about how their rifle breaks. It's a short two-stage design meant to feel a lot like a good 1911 press, with a defined take-up, a clean wall, and a break with genuinely zero creep. The magic is the Frictionless Release system: instead of sliding sear surfaces that need polishing and lube, a free-floating roller sits captured between the sear and the hammer. That means nothing drags, nothing wears in a way that shifts your pull weight, and the feel stays the same whether you've run a thousand rounds or ten thousand.
This is the Pro Curved lever version in black, which gives you a subtle curve that a lot of folks find more natural under the finger than a dead-flat shoe. Because there's truly no creep, most people report the pull feeling around half a pound lighter than a friction-based trigger measured at the same weight. It's a real difference at the range, and it shows up most on smaller targets and longer shots where a mushy break costs you.
Pull weight adjusts from 1.5 to 4 pounds in 2-ounce increments using CLKR technology, and you do it with a set screw while the trigger is installed in the rifle. Changing the weight never touches hammer force, so the flat-wire hammer spring keeps hitting hard enough for reliable primer strikes even on tougher ammo at the lightest settings. TKR technology keeps overtravel under 0.015 inches, so your sight picture barely moves through the break, and the reset is short and positive for quick follow-ups.
Construction is where this thing earns its keep. The housing is anodized 7075 aluminum with hardened 440C stainless internals and a black PVD finish, so it shrugs off weather, corrosion, and hard use. It's a drop-in unit for mil-spec AR-10 and .308 lowers, and it's backed by TriggerTech's lifetime warranty. Whether you're building a PRS-style precision rig, a hunting gun, or a do-it-all .308, this is one of the more refined triggers you can bolt into the platform.
No, trigger pins are not included in the box. It uses standard mil-spec 0.154-inch pins, so if you don't already have a set on hand you'll want to grab one before install. Most AR-10 lowers already have compatible pins you can reuse.
Yes, it's a drop-in design made for mil-spec AR-10 and .308 pattern lowers, including pump-action AR builds. Just note this is the AR-10 version specifically, not the AR-15 model, so it's matched to the .308 platform. If your receiver is mil-spec, you're good to go.
TriggerTech's CLKR technology lets you dial the pull from 1.5 to 4 pounds in 2-ounce increments using a single set screw. Best part is you can do it with the trigger already installed in the rifle. Adjusting the weight doesn't change hammer force, so you keep reliable primer ignition even at the lighter settings.
Instead of sliding sear surfaces that wear and need polishing or lubrication, TriggerTech uses a free-floating roller captured between the sear and hammer. That eliminates creep and keeps the feel consistent over thousands of rounds. Because there's no drag, most people say the pull feels about half a pound lighter than a friction trigger set at the same measured weight.
