Worked on palmetto state armory lower with a lot of work - CMMG, Inc Accuwedge, AR15

The lower receiver cavity where you place this piece on the PSA lower is quite shallow.
To make this fit I had to cut down the base with a well sharpened knife as THIN as possible to the point I was wondering if it would do anything.
Then I had to cut off the front 1/3 of the base.
With all that trimming it just barely fits but it does take all the wiggle out of the my ar15.
It is a little more difficult to push in my rear takedown pin when putting the receivers back together. Because the fit is so tight I do have to use a punch to push out the rear takedown pin.
Overall I’m happy because the product did what I needed it to but with some work.
