Is this a pump or semi-auto

James, this is a semi automatic 12 gauge bullpup shotgun. Hope this helps.

James, Semi-Auto Action Shotgun. 10rd and 15rd magazines here : https://www.budsgunshop.com/product_info.php/products_id/411559964 ------------------------------- https://www.budsgunshop.com/product_info.php/products_id/714025798

James, this is semi auto. Have a great day!

Will these drum magazines need to be modified for proper fitment?

Robert, no Sir. AR-12 Style magazines and drums will work : https://www.budsgunshop.com/product_info.php/products_id/714025798/promag+mka+1919+12ga+275+15rd+drum -------------------------------- https://www.budsgunshop.com/product_info.php/products_id/111608/promag+mkaa1+akdal+12+gauge+mka+1919+275+20rd+black+drum

This works with mka 1919 or AR12 magazine or drums. Any of those wont require modifications. Sometimes new magazines or drums will fit very tight but after using them awhile will loosen up. Hope this helps.

Robert, yes Sir, the 15rd MKA-1919 drum is narrower and fits better and the 20rd drum is wider and creates a more unnatural shoulder angle on a bullpup : budsgunshop.com/product_info.php/products_id/714025798/promag+mka+1919+12ga+275+15rd+drum ---------------------------- budsgunshop.com/product_info.php/products_id/111608/promag+mkaa1+akdal+12+gauge+mka+1919+275+20rd+black+drum

Robert, yes this will take mka 1919 drum mags. >>> budsgunshop.com/product_info.php/products_id/714025798/promag+mka+1919+12ga+275+15rd+drum ....or budsgunshop.com/community.php/q/view/q_id/70740/Total+length .....Have a great day!

This will also take AR12 magazines or mka 1919 magazines. Like item number MKAA1 just type the item number into buds search or just use buds search and type in AR12 magazine or mka 1919 magazine. Hope this helps.
