Q: What would you say is gained by replacing the secondary spring and the sear spring versus merely replacing the main trigger return spring?

A: The T/C Compass Trigger Spring Kit is designed to work without the adjustment nuts since the trigger pull we be at the lightest setting. We are also including 2 main trigger return spring options that will allow target shooting or hunting rifle setups. It's an overall combined trigger pull reduction. Making it a safer and better feeling trigger pull reduction.

Q: I have heard various people say that they practiced a drop test after using the other aftermarket spring, but it is hard to make sense of what exactly a "safe" drop height for a rifle in the "Fire" position is. Do you have any thoughts on this? How different would a TC Compass with your trigger kit respond to a drop test than any other common rifle with a good trigger?

A: Our drop test is from 6" on hard concrete and then from 12" onto a rubber mat. Testing the trigger each time to make sure it didn't fire.

Q: Is there anything fundamentally trickier about the TC Compass/Winchester Model 70 trigger than any other trigger as far as safety and trigger pull harmony goes?

A: TC made a voluntary recall on their rifles to fix the trigger. They received too many complaints that it would not pass a minimal drop test. In an effort to fix what they already had they added the counterweight and another trigger return spring.

Made a decent shooting gun into a GREAT shooting gun. Don't know exactly how much it reduced the trigger pull but it is much nicer to shoot. Fairly easy to replace the old springs the only caution is with the little trigger spring it is in such a position that you need to be careful not to drop it the little booger is hard to find if it goes on the floor, other that that love your product. Thank you

It Works

Took a week to arrive, OK, it's USPS. The installation took about 20 minutes which included my taking the time to polish the sear. I used the 'Bench-Rest' spring. My trigger measured a solid 5 lbs before and after the install, it's down to a crisp 2.5 lbs. Not sure what the 'hunting' spring would have brought it down to or if I'll see any improvement after shooting it a few times, but, I can live with 2.5 lbs. I am a little disappointed in one thing, for $20 I would think you guys could include a tiny tube of the grease you use in the video, just saying. The video is Very helpful, thank you. Until someone actually makes an after market trigger, I will certainly recommend this kit.
