Gunsmithing FN receiver mod for CDI bottom metal

[Lexington]

I had my FN SPR receiver modified to accept CDI bottom metal and AI mags. (Actually, the receiver does not need to be modified for the BM, specifically, but it does need to be mod'ed to fit the mags.) It's been a while since I had the work done, but I think the instructions said to remove the entire front mag well wall. My memory there is thin and the instructions were 4th order photocopies. My smith and I decided to do only what we thought was needed. I was against removing a whole lot of material unnecessarily. The photos show what he did. The AI mags seat perfectly with no slop.

Please show photos of your FN receiver mods and discuss how well they work for you.

Does anyone have a picture of the conversion they had done at CDI Precision? I'd like to see what "correct" looks like.

It will look like the extended outline of the mag well only .250 (1/4") deeper. (I am pretty sure CDI goes 1/4 deep).

Mine was done by Jeff at CDI.
