James, yes, the SDS Imports Turkish AR12 12GA 10rd Magazine is compatible. This shotgun will take AR12 magazines and mka 1919 magazines/drums. Here's a link to a 20 round drum that will fit if interested. Hope this helps, link here.......... https://www.budsgunshop.com/product_info.php/products_id/131370/sds+imports+t20rdm+replacement+magazine+12+gauge+sds+imports+turkish+1919+20rd+black+polymer+drum

James, yes it is. The Centurion OPTIO-I accepts all AR12 or MKA1919 style magazine or drums. Have a great day!
