So first of all i wanted to tell everyone that im not responsible if you destroy your stock. Next if you are a visual like me you will like to see the pictures.
First this is my usgi stock that will be going to get repaired later becaused its cracked in many places.

The promag unit


Now the mod secure the stock in a vise or anything you want be carefull to not scratch it.

Then i protected the surrounding area with tape.



Then took some measurments as stated in other threads about this its 6" 1/4 long . I decided to file down only the remaning bit thatis about 1" 1/2 long. I had marks before measuing when i trial fited it before.

I measured about 1/8 deep that needs to be taken out. It can be less on your M14.

Then the tools i used 2 diffrent files and a razor blade to cut of excess and 180 and 320 grit sand paper.



Then start filling. BTW I messed it up a little as i started to make the "angle" in the wrong direction. In the end it didnt change anything, but i had to remake the slop here are the diffrent steps while i was cutting away.



Lastly some pictures with a level to show the angle because it was hard to see on the pictures. Enjoy




When i got home i fitted it in and their was some areas that needed filling more. Picture time !


Then i shaved the trigger fitting pads as per instructions no pics sorry. Then the trigger group went in pushed very hard and it locked. I flipped the gun over to check clearence and as you can see on the pictures it was still rubbing a little i used a razor blade to outline the excess then ill go file it down again tomorow. On one picture you can see its not sitting right its angled to the left.



I really hope I helped someone with this pictorial if you have something to ad or ask tell me. Thank you.
