Sig Sauer Two Stage match trigger upgrade for Tread M400 but you can use it in any milspec receiver.

Purchased and opened but never used, I’m a single stage trigger person when it comes to AR’s

Its a flat trigger with a slight curve it and it breaks around 5lbs according to Sig.

Will Ship for free up to $10 in shipping cost in the states only. All sales final.

Might consider meeting local for anyone whos local.

I accept Venmo and Apple Cash at the moment.

Please let me know if you have any questions.
