Both the Egyptian rifles use a 5 rd clip unique to those rifles. A mauser clip will fit but won't sit low enough in an FN49 to properly strip the rounds into the magazine. Both clips pivot down into the magazine. The clips have only 2 bumps on the side unlike the usual 3 bump K98 clipsThe FN I believe has parts available . What I didn't like about mine was I couldn't find stripper clips for it and had to hold the bolt open with one hand while loading up to 7 or 8 cartridges with the other . Otherwise , no problems.
