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.

Disappointed
Original trigger pull was about 6.25lbs. Replaced with 2.5lb spring got it down to 4.25lbs. Replaced with 1.5lb spring, no change, still 4.25lbs.
It did reduce the trigger pull, but not anywhere near what I was looking for (3lbs).
T/C Spring kit - NICE!
This spring kit made a big difference in my Compass rifle. The trigger feels much better and I have no doubts when I fire it, it'll be exact. I polished up all the trigger group and lubed it with the grease and I couldn't be happier. Not TOO light, but feels like a comp trigger for much less. I don't think you'll be disappointed.
Install was easy with the YouTube video, so don't be intimidated taking it apart, it's not complex.
i did not achieve the results in the installation video but i did reduce trigger pull by over 2 lbs.
followed the installstion video and reduced trigger pull by 2lbs. 2oz. was fairly easy to do with the help of the video

Fast Shipping. Works like it should. Thanks
Better
Original pull averaged 6.5 lbs. I put in the 2.5 lb spring and only dropped to 6lb. Installed 1.5 spring and got it to 4 lbs. Definitely better but I would have liked around 3lbs. Installation was very easy after watching video

Springs were very easy to install by watching the MCarbo video on YouTube.
When reinstalling the trigger it can twist a little making it hard to install the hinge pin. Just use a small punch to help align.
Everything in the video is needed to make installation easy.
I used the 1.5 lb spring which took the trigger pull from 5.5lbs down to 3.5lbs and very smooth.
FYI the 2.5lb spring reduced trigger pull down to 4.5lbs.

This spring kit is just not compatible with the Gen 2 triggers, so depending on your rifle, if it has the original trigger this spring kit will work for you!
Will this fit a Thompson center Compass 2 also?
Good morning Austin, unfortunately, our kit is not compatible with the Compass II. Sorry for the inconvenience!
