TC Icon

[sti_warrior]

Anyone here own a Thompson center Icon that could tell me size and thread pitch of the action screws on this rifle?

I also wanted to change the trigger on this rifle, but nobody sells one, what would be a near fit, I was told maybe anchutz but i find it fairly similar to REM 700 trigger, I wonder if I could make this trigger work. Please help.

REM 700
this is a pretty close fit, i would have to machine the top piece that holds the bolt back, I would also need to shave the top of the trigger for the holes to match properly, and modify the stock a little, trigger is longer so I dont know if it will fit the trigger guard, maybe someone with a little more skills than me can help.

If someone can make this work this trigger fits TC ICON, TC VENTURE and TC Dimension so alot of customers out there for an easy project

I have one, but don't know off the top of my head what the action screw size/pitch is, nor do I have an easy way to determine what it is even if I pull my rifle apart.

As for the trigger, I cut what I can only describe as the trigger pre-load spring (behind the trigger pull weight adjustment screw/nut on the trigger housing) a bit and noticeably lightened the pull (I was inspired by the Howa HACT trigger mod).

I started a thread sometime back when I was actively working on that particular rifle, and posted pretty much everything I was able to learn about the Icon.

I have seen your thread many times, thanks for replying I own 2 Icons and looking for a third one in 6.5cm but have not found one yet.
