I can't say, but the frame on my FE 12ga, won't accept a feild grade or CEO butt stock because the frame of the FE that I have is nearly 1/4 inch taller than a standard 12ga 1894 frame...I found that out the hard way...I bought a 12ga CEO buttstock, only to find out that it wouldn't fit the 12ga FE, but does fit any standard 1894 frame...I've had to re-stock the FE, and hunt up another straight grip tang just so I could use the CEO stock on some future Frankenstien...
