Description
The stock trigger on a Ruger Precision isn't bad, but it holds a lot of rifles back from their real potential. That's where the Timney 650ST comes in. This is a self-contained, 100 percent drop-in unit that swaps into your RPR without gunsmithing, fitting, or fussing with springs and stones. Most folks have it installed in about 15 minutes with the help of a YouTube video, and the difference is noticeable the moment you press it.
What Sets the 650ST Apart
This is a two-stage design with a straight trigger shoe, which a lot of precision folks prefer for the consistent finger placement and predictable feel it gives from prone to a bag. It arrives factory calibrated with a half-pound first stage and a one-pound second stage, so you get a light, defined take-up followed by a clean break with no creep. If you want to dial it in further, the first stage adjusts from 1/2 pound up to 1 pound and the second stage runs from 1/2 pound all the way to 2 pounds.
How the Timney 650ST Is Built
Timney doesn't cut corners on the internals. The housing is machined from military-grade 6061-T6 aluminum and anodized for durability, while the trigger itself is CNC machined, heat treated, and coated. The sear is wire EDM cut, hardened to 58-60 Rockwell, and finished with a Teflon-nickel coating for smooth, dependable engagement over the long haul. Every unit is individually tested and calibrated by hand before it ships, which is a big reason these triggers feel so consistent shot after shot.
Getting the Most From Your Ruger Precision
Where this trigger really earns its keep is repeatability. Folks who've measured stock RPR triggers on a gauge often see pull weight wander a few ounces between shots, while the Timney holds steady test after test. That kind of consistency is exactly what you want when you're chasing tight groups at distance. Whether you shoot matches, ring steel, or just want a better break behind the rifle, the 650ST is one of the most worthwhile upgrades you can make to a Ruger Precision.

Frequently Asked Questions
Is the Timney 650ST a true drop-in for the Ruger Precision Rifle?
Yes. It's a fully self-contained, 100 percent drop-in unit that installs in your RPR with no gunsmithing, fitting, or adjusting required. Most owners have it swapped in around 15 minutes with basic tools. It fits both Centerfire and Magnum Ruger Precision rifles.
Can I adjust the pull weight on the 650ST?
You can. It ships factory calibrated at a half-pound first stage and one-pound second stage. From there, the first stage adjusts between 1/2 and 1 pound, and the second stage adjusts between 1/2 and 2 pounds, so you can dial in the feel you want.
Why choose the straight trigger over the curved version?
The straight shoe promotes consistent finger placement and gives many precision folks a more predictable, repeatable press, especially shooting off a bag or bipod. It comes down to personal preference, but the 650ST is the straight version if that's the feel you're after. Timney also offers a curved model for those who prefer it.
Will this fit a Gen 2 Ruger Precision Rifle?
Later-generation RPRs use a trigger assembly with a J-slot cutout, so you'll want to confirm your rifle's generation before ordering. If you have a Gen 2 rifle, verify the trigger version matches the slot design in your stock assembly. When in doubt, check your rifle's serial or reach out to us and we'll help you sort it out.
