Did you do it or have a gunsmith? I have the parts kit but haven’t gotten around to researching the install.
Did it myself. It wasn’t bad if you’re somewhat mechanically inclined. My father-in-law and I worked on it together. He has a non-SRT Mk-25, so it was cool to compare the two side by side when we were done (took around 20-30 minutes).
I bet there is an installation video online somewhere.
