Im sure it's been covered in threads but after a ton of research I couldnt find a thread that covered WHAT exactly to file away.

Hopefully this helps those who are going to run the krg impact action combo.

This little ridge around the screw is what needed to be reduced. As well as a low profile screw head, which I just filed down as well

Using a small, flexible file I slowly started to reduce that lip. Of course it helps to tape off the surrounding areas to avoid unwanted filing.20190425_201841.jpg

After a few hours of filing and checking the trigger hanger clearance I finally got enough material removed. I did test this without the front trigger hanger screw installed.

I went to the local hardware store to match threads and bought a couple spares. Took them home and filed down one of them to be low profile. It now sits flush without any wobble from the hanger or screw.

Update:

1/4-28×1/2" front screw with a few washers stacked under the spine of the chassis...will need to order the same diameter and thread for the rear but needs to be 1 3/4" or 2"...will have to find someplace local.IMG_20190426_221252_234.jpg

Another update...KRG sent out a long enough action screw. ( 1 3/4" long, same thread pitch as the front screw) IMG_20190428_190820_102.jpgCant say enough about the customer service from them. Grabbed a birchwood casey black touch up pen for aluminum (looks like a blue capped sharpie) and took care of the raw aluminum showing. Matched pretty well. Takes several time to go over it but ut matches flawlessly. Apply, let dry, wipe away with finger, repeat. When done add a drop of oil on it, wipe excess and youre done.

Thank you for the write up!!!! Should be pinned with as much as this subject comes up
It couldve gone by faster if I had a mill or something mechanical but I had the time and was in no rush.

Low profile hanger screw, low profile trigger guard screw and that little bit of material was all I needed to get it to sit flush.

Oh and the screw lengths were another variable but nothing major.

If it can be pinned id be cool with it. Help those out that are looking for the same combo.
