Description
Anyone who's spent time behind a stock Ruger 10/22 knows the trigger is the weak link. That gritty, heavy pull fights you every shot and works against the accuracy the little rifle is capable of. The Timney 10221C fixes that in one move. It's a complete drop-in trigger assembly set at 2.75 pounds from the factory, a single-stage curved trigger that breaks clean with no creep, calibrated and tested by hand before it ships. No gunsmith, no fitting, no fuss.
What Sets the Timney 10221C Apart
This isn't just a lighter spring in the old housing. The trigger, sear, and hammer are wire EDM cut and heat-treated steel for long-haul durability, all riding in a one-piece CNC-machined 6061-T6 aircraft-grade billet aluminum housing. Timney has been building triggers since 1946, and that experience shows in the consistency of the break and the tight, wiggle-free fit into the receiver. Folks who install one routinely report groups tightening up simply because the trigger stops getting in the way.
Living With the 10221C at the Range
Two features win people over fast. The extended magazine release drops mags with a flick of a finger, a huge step up from the awkward stock lever, and the auto bolt release lets you pull the charging handle back and let it go to chamber a round or lock the bolt. If you've ever fumbled with the factory bolt catch, you'll appreciate how much smoother this makes things.
Installing the Timney 10221C
Installation is about as simple as it gets. Punch out the two receiver cross pins, lift out your old trigger group, drop the Timney assembly in, and push the pins back through. Most people have it done in about five minutes with basic tools. The housing fits any standard 10/22 stock, so whether you're running a Carbine, Sporter, Takedown, Target, or Tactical, it goes right in and gets you shooting better.

Frequently Asked Questions
Does the Timney 10221C fit all Ruger 10/22 models?
Yes. The housing drops into any standard 10/22 receiver and stock, so it works with the Carbine, Sporter, Takedown, Target, Tactical, Lite, and Compact. It's a straight swap for the factory trigger group with no fitting required.
How hard is the 10221C to install?
It's about as easy as an upgrade gets. You push out the two receiver cross pins, remove the old trigger assembly, drop the Timney unit in, and push the pins back through. Most people finish in about five minutes with basic tools, and if you're comfortable pulling your trigger group for cleaning, you're set.
Is the 2.75 lb pull weight adjustable?
No, this model is factory-set at 2.75 pounds and non-adjustable. Timney hand-calibrates and tests each unit before it ships, so it arrives ready for the range with a clean, creep-free break right out of the box.
What's the deal with the extended magazine release and auto bolt release?
The extended mag release lets you drop a magazine with a single finger, which is a big improvement over the fiddly stock lever. The auto bolt release means you just pull the charging handle back and let it go to chamber a round or lock the bolt, cutting out the awkward dance the factory bolt catch requires.
