The trigger is where accuracy really starts, and the CZ 457 is a rifle that deserves better than a heavy factory pull. Timney's replacement trigger for the 457 gives you a clean, repeatable break with a pull weight you can tune anywhere from 10 ounces up to 2 pounds. That range covers everything from precision benchrest work to a slightly heavier setting for walking the woods, so you can set it up to match how you actually shoot.
Every part in this trigger is machined from premium tool steel rather than metal injection molded or stamped pieces, which is a big part of why the break feels so consistent. The sear and trigger shoe are heat treated to 56 Rockwell, the trigger shoe wears a black oxide finish, and the sear gets an NP-3 coating for slick, low-friction movement that holds up over the long haul. It also carries a trigger-blocking two-position safety, so you keep familiar function while gaining a much better feel.
The standout feature here is Timney's Sear Engagement Adjustment Lock, or SEAL'd design. It lets you set your sear engagement and overtravel, then lock those settings in place so your pull stays put shot after shot. Many units show up pre-set right around a pound and break cleanly out of the box, and plenty of owners report dialing them down even lighter with no perceptible creep. If you're new to trigger tuning, the included instructions walk you through it without any guesswork.
Installation is about as painless as rifle work gets. This is a genuine drop-in unit for CZ 457 actions, and folks who've tackled it consistently call it a quick job with basic tools. Whether you're chasing tighter groups in rimfire competition or just want your hunting rig to feel like a proper precision rifle, this is a straightforward upgrade that pays off every time you press the trigger. It's covered by Timney's No Hassle Lifetime Warranty for peace of mind.
Yes, this trigger is built specifically for CZ Model 457 rimfire actions and drops right in as a direct replacement for the factory unit. It's designed around the 457 platform, so you get a clean fit without modifying your rifle. If your rifle is a 457 variant like the Varmint, Lux, or American, you're good to go.
The published range is 10 ounces up to 2 pounds, so you can tune it for delicate precision work or set it a bit heavier for field use. Many arrive pre-set around a pound and break cleanly right out of the box. Some owners have reported getting theirs even lighter than 10 ounces, though the 10 oz to 2 lb window is the rated spec to work within.
Not at all. It's a genuine drop-in unit, and most people find it a quick job with basic tools and the included instructions. If you can remove your barreled action from the stock, you can handle this swap.
SEAL'd stands for Sear Engagement Adjustment Lock, and it lets you set your sear engagement and then lock it in place. That means your pull stays exactly where you set it, shot after shot, without drifting out of adjustment. It's a big reason this trigger delivers such a repeatable, consistent break.
