Description
The Timney #401 is one of those upgrades that changes how a rifle feels the moment you take it to the range. It replaces the factory trigger on your Winchester Model 70 with a hand-fitted, precision-machined unit that breaks clean with no creep and no guessing. If your groups have been opening up and you can't figure out why, a lot of the time the culprit is a mushy factory trigger, and this is the fix folks reach for first when they start accurizing a Model 70.
What the #401 Brings to a Model 70
This trigger fits both pre-64 and post-64 Model 70 rifles, and it can be adapted to the older Model 54 by building up the cocking piece to Model 70 contour. It's built around a lightweight alloy housing with steel working surfaces that are machined, hardened, ground, and polished, so you get consistency shot after shot. One thing worth knowing up front: the #401 does not work with rifles that came with the Winchester Factory MOA trigger system. If yours has the MOA setup, the Timney #402 is the one you want instead.
Dialing In the Timney #401 Trigger
What makes this trigger a favorite is how much control it hands back to you. Pull weight is adjustable roughly between 1 and 3 pounds depending on how light you like it, and it's also adjustable for sear engagement (creep) and overtravel. It ships factory-calibrated and set around 3 pounds, so plenty of people run it right out of the box, but the option to fine-tune it is there when you want it. Adjustments are made with a couple of common hex wrenches.
Installation Notes Worth Knowing
Timney redesigned this trigger to make installation more straightforward, and many owners handle it at the bench without a gunsmith. That said, the Model 70's bolt release and safety setup can be finicky, so it pays to check safety function through all three positions after the swap and follow Timney's included instructions closely. Some rifles benefit from minor fitting. If you're not comfortable doing that work, having a gunsmith install it is time and money well spent. Every Timney trigger is made in the USA and backed by a lifetime warranty.

Frequently Asked Questions
Will the Timney #401 fit both pre-64 and post-64 Winchester Model 70 rifles?
Yes. The #401 is designed for both pre-64 and post-64 Model 70 actions. It can also be adapted to the older Model 54 by building up the cocking piece to the Model 70 contour.
Is the Timney Winchester 70 Trigger a true drop-in, or does it need fitting?
Most standard Model 70 rifles install cleanly with no modification, and Timney redesigned the #401 to make the job easier. Some rifles, along with clone actions, may need minor fitting or a slight adjustment for the safety to function correctly. Move the safety through all three positions after installing and follow the included instructions closely.
Will this work on a Model 70 with the Winchester Factory MOA trigger system?
No. The #401 is not compatible with the Winchester Factory MOA trigger system. If your rifle has the MOA setup, you'll want the Timney #402 instead. If you're not sure which trigger your rifle has, it's worth confirming before ordering.
How light can I set the pull weight on the #401?
Pull weight is adjustable in the range of roughly 1 to 3 pounds, and it comes factory-calibrated around 3 pounds. It's also adjustable for creep and overtravel, so you can tune the whole feel to your preference. Adjustments are made with common hex wrenches.
