the falcon ft stocks are to long for an fn12 by about 4", i would guess the standard ones are the same.

Probably wrong but I'm sure I had a Lighthunter 12 in a 19" stock
...definately fit in terms of inletting the only risk as mentioned above is that the stock could potentially be longer than the reservoir. From memory however the standard stocks were same length
Quick measure on my Std fn19 and Hawk and I reckon it will fit with 1" to spare.
