The MK IV sear has been modified to accept the mag disconnector. The MK III sear has not. You would have to replace the hammer also to get it to work. I'm not sure if the III hammer and sear will work in the IV.

How about if you put a mkiii mag disconnect and VQ sear in the mkiv?

I have heard that a Mkll hammer bushing and the target sear will work in the MklV. The MklV trigger is different if you want to upgrade to an adjustable trigger. Both TK and VQ have come out with a compatible trigger that fits.
