I'm rather opinionated and set in my ways.
Big salt shaker required. . .
I've used LOTS (probably close to 100 when I worked for Nesika) of H/S detachable magazine floor metals. They work, the guns shoot fine, but I have to tell you that I personally cannot stand the dern things.
The floor metal is cast and it's intended for an H/S stock. A traditional hunting stock will quite often have to be windowed in order for the floor metal to marry up with the belly of the stock. It ends up with a presentation that I personally don't care for at all. For the guns I installed these in, I used an optical comparator and metrology software to map the outside contour of the part. With other floor metals I only had to do this once. With an H/S I had to do it with every one of them because they vary too much.
If being used in a slimline sporting stock its very easy to have the feed lips getting very close to the bolt when attempting to put the floor metal flush with the stock.
Last, I personally find a $200 plus dollar floor metal rather tacky when a rubber O ring is used to shim the bottom of the magazine to the floor metal.
IMHO there are better alternatives.
Hope this helped.
