Kevin, this model, if unmodified, takes Colt Style Magazines : budsgunshop.com/product_info.php/products_id/713078226/cpd+magazine+ar15+9mm+32rd

Kevin, unless the gun has been modified, it will take Colt style magazines. Have a great day!

From the looks of the magazine well it looks like it takes colt magazines. Since this is used there's no way for us to know for sure since we're customers as yourself not buds employees. You would have to contact buds customer service at 859-368-0371 Monday thru Friday 9am to 9pm or use the blue chat button at the bottom right corner of your screen. They'll be able to assist you. Sorry can't give a definite answer but hope this helps some.
