Yes, item VC4AK and VC4AK-ST will fit your gun. We recommend having this installed by a qualified gunsmith, but if you are familiar enough with taking apart and re-assembling firearms, you should still be able to do it yourself.

I had Volquartsen install this for me on my Mark IV 10/45. I have done a lot of modifications on my Ruger 10/22 TakeDown but I really don't know enough about the Mark IV to try it myself. VQ did a great job-took a little over a week. I got a new trigger pull tester and was trying it on my guns and the Mark IV pulled a two and a half pounds with a quick reset.
