The Timney 649ST is a self-contained, 100 percent drop-in trigger built specifically for the Ruger Precision Rimfire. It swaps out the factory unit as a single complete assembly, so there's no fitting, filing, or adjusting to fumble through. You pop out the old one, drop in the Timney, and you're back to shooting with a genuinely better trigger under your finger. It fits RPR models chambered in .22 LR, .22 WMR, and .17 HMR, and this version wears the straight (flat) trigger shoe for folks who prefer that vertical finger placement.
This is a true two-stage design, and it comes from the factory calibrated to a half-pound first stage and a one-pound second stage. The first stage is user adjustable from 8 ounces up to 1 pound, and the second stage adjusts from 8 ounces to 2 pounds, so you can tune it light for benchrest and NRL22 work or leave it a touch heavier for field use. The result is a smooth take-up that stacks against a clean wall, then breaks with almost no creep. Rimfire competitors who want to squeeze every bit of accuracy out of their rifle tend to notice tighter groups right after the swap.
The housing is CNC-machined from military-grade 6061 T6 aluminum and finished with a blued anodized coating for durability. The straight trigger shoe is heat treated, and the sear is wire EDM cut, hardened to 58-60 Rockwell, and Teflon-nickel coated to keep the action slick and consistent over the long haul. It's assembled in the USA, which is a big part of why Timney has such a solid reputation among Ruger owners.
One of the best parts is how quick this goes in. No special tools or gunsmith visit required, just a basic swap that most owners knock out in a few minutes at the kitchen table. If the mushy factory blade has been holding back your rimfire game, this is the fix that gets talked about most.
Yes, this trigger is made specifically for the Ruger Precision Rimfire and works with the RPR chambered in .22 LR, .22 WMR, and .17 HMR. It's a self-contained drop-in unit, so it fits without any fitting or modification. Just confirm you have a Rimfire RPR and not a centerfire Ruger Precision Rifle, which uses a different Timney model.
The first stage adjusts from 8 ounces to 1 pound and the second stage adjusts from 8 ounces to 2 pounds. It ships factory calibrated at a half-pound first stage and one-pound second stage, which is a great starting point for most people. You can dial it down lighter for competition or leave it as-is for a crisp, repeatable break.
No, the 649ST is a 100 percent drop-in with no gunsmithing, fitting, or filing required. Most owners have it installed in just a few minutes with basic hand tools. You pull the factory trigger group and drop the Timney right in its place.
The only difference is the shape of the trigger shoe. The 649ST is the straight, flat-faced shoe that many precision shooters prefer for consistent finger placement, while the 649 uses a traditional curved shoe. Internally they perform the same, so it comes down to feel and personal preference.
