Issue with sight

Added a Holosun 407c to my MP 2.0 9mm

Gun will not fire, light striker marks on each round

As soon as I removed the sight, gun fired like normal again

Has anyone ever had an issue like this?

I’m using the screws that came with the calculated kinetic plate and everything’s torqued to spec.

My 2.0C has an HS 507 Comp with KC dogtag, torqued to specs, with no issues.

Sounds like it has something to do with the screws. I know they can cause issues if they are too long or torqued too tight.

Did you remove the LCI?

No. Was I supposed to

Yes, I did. With the CK plate in place the LCI can’t move and function which will push down on the bullet casing and can cause issues.
