Anyone who has spent time behind a Ruger M77 MKII knows the factory trigger leaves plenty on the table. There's usually more creep than you'd like, a long stretch of overtravel, and a pull weight that fights you right when you're trying to break a clean shot. Timney's #1100 kit is built to fix all of that. It's a right-hand drop-in trigger, sear, and reduced-weight spring designed specifically for the M77 MKII, and it turns a serviceable rifle into one that genuinely feels tuned.
The heart of this kit is precision. The sear is EDM-cut, heat treated, and nickel-plated steel, and the engagement surfaces are machined and polished so the break comes off crisp instead of mushy. It ships factory calibrated and ready to shoot, but the real appeal is the adjustability. Conveniently placed set screws let you tune sear engagement (creep), overtravel, and pull weight to your preference. With the included reduced-weight spring you can run it down in the 1.5 to 2 pound range, and if you'd rather keep things heavier for field or hunting use, the factory spring lets you set a stiffer pull.
This is a job most folks can handle at the bench with basic tools. Pulling the old parts takes just a few minutes, and the new sear, trigger, and spring go right in. Depending on your specific rifle, you may need to do a little light filing to get the safety clearance right, so follow the printed instructions closely and check safety function before heading to the range. Take your time on that step and the payoff is a trigger that breaks like glass.
The #1100 is made for right-hand M77 MKII actions and also fits newer Hawkeye rifles running the LC6 trigger. It is not designed for VT rifles that came with a factory two-stage trigger. If you're not sure which trigger your rifle has, a quick look at the factory unit before ordering will save you a headache. For left-hand actions, Timney offers the companion model 1102.
Yes, this trigger is built for right-hand Ruger M77 MKII actions and also fits newer Hawkeye rifles that use the LC6 trigger. It is not made for VT rifles that shipped with a factory two-stage trigger. If you shoot a left-hand rifle, Timney makes the matching model 1102 for you instead.
With the included reduced-weight spring you can dial the pull down into the 1.5 to 2 pound range, which is where a lot of folks land for a crisp, clean break. If you want a heavier pull for hunting or general field use, swapping back to the factory spring lets you set it stiffer. The set screws also let you fine-tune creep and overtravel to taste.
The core install is quick, with the old parts coming out and the new trigger, sear, and spring going in with basic hand tools. Depending on your specific rifle, you may need a bit of light filing to get proper safety clearance, so following the instructions and verifying safety function is important. Plan for a little bench time and you'll end up with a much better trigger.
The factory M77 MKII trigger is known for heavy pull, noticeable creep, and long overtravel. The Timney kit replaces that with precision machined, polished engagement surfaces and an adjustable pull for a break that's noticeably crisper. It's one of the more meaningful upgrades you can make for better shot placement out of these rifles.
