There's a moment the first time you run a Timney where you realize how much a factory AR trigger was holding you back. The 667SST Competition Trigger delivers a clean 3 lb single-stage pull with zero creep and a wall that breaks like glass, giving you the kind of predictable release that makes tight groups feel repeatable instead of lucky. The straight (solid) shoe gives you consistent finger placement shot after shot, which is exactly what you want when you're shaving fractions off your groups or running a match stage.
This is a self-contained cassette-style module, meaning every component lives captive inside a lightweight aluminum alloy housing. The hammer is wire-EDM machined from S7 tool steel, chosen for its toughness so it shrugs off years of hard use without chipping. The rest of the internals are EDM cut from A2 tool steel and heat treated to Rc 56-60, so the engagement surfaces stay crisp and consistent over the long haul. Every unit is tested and calibrated by hand before it ships, which is a big part of why Timney has earned its reputation since 1946.
Dropping this in is about as painless as AR upgrades get. It's a 100 percent drop-in design that uses your rifle's original hammer and trigger pins, with a proprietary layout that helps keep those pins from walking out under recoil. No filing, no stoning, no adjusting. Most folks have it swapped and back together in a matter of minutes with basic hand tools.
The fixed 3 lb weight sits in the sweet spot for competition, precision work, and general range shooting where a light, clean break matters. Keep in mind this is the small-pin version, built for AR-15 lowers with .154 inch pin holes, which covers the vast majority of mil-spec rifles out there. If you've been chasing accuracy and blaming your barrel, a trigger like this is often the honest fix that tightens things up fast.
This is the small-pin version, so it's made for AR-15 lowers with .154 inch trigger and hammer pin holes, which is the standard on the vast majority of mil-spec rifles. A handful of older Colt models use larger .170 inch pins and would need the large-pin variant instead. If you're running a typical mil-spec lower, you're good to go.
No, this model comes factory-set at a fixed 3 lb pull and is not user-adjustable. Timney calibrates and hand-tests every unit before it ships, so it arrives dialed in and ready to run. If you want a different weight, Timney offers this same competition trigger in 4 lb and 4.5 lb versions.
Not at all. It's a 100 percent drop-in cassette that uses your rifle's existing hammer and trigger pins, with no fitting, filing, or adjusting required. Most people have it installed in just a few minutes with basic hand tools.
The 667SST uses a solid straight shoe, which gives your finger a flatter, more consistent contact point and can make the break feel lighter and more controlled. A lot of competition and precision shooters prefer the straight profile for that repeatable finger placement. It comes down to personal feel, but the straight shoe is a popular choice for accuracy-focused builds.
