Probably, but you might have to do some cutting/sanding/filing to make it fit.
Also, those trench mags are terrible for .308.
I had to do alot of that cutting/sanding/filling to make it fit my israeli DOU43, and it fed like #### because of the shorter round. If you were to add an additional block to the magazine to make the rounds more snug, it will probably feed better, but I found it all a big waste of time.
