Botach has Springfield .308 15RD magazines for your M1A. It's showing in stock for $49.95. Probably not much of a deal though but shipping is free and the capacity is correct.

You can find CMI 10 and 15 rnd mags cheaper on gun broker you check every day.

25 on midway usa for cmi...

Got it, nevermind. You can all ignore this bone-headed post. There's a reason why I do not own a M1A.

 

I did learn that you can use a different mag with the M1A.

A for effort however, a good deal is always appreciated so thanks anyway

 

I bought some 15 round CMI's from Brownells for 25 each
