Hi Todd and welcome. No Sir. It is tube fed only. 2rd tube extension here takes it from a 5+1 to a 7+1 capacity : https://sdsimports.com/mac-1014-magazine-extension/

This shotgun has a tubular magazine restricted to 5 rounds. The proper 7rnd tube can be swapped in. MAC claims a 98 percent parts compatibility with Benelli M4's, with only a few small trigger components being different. Therefore most parts will carry over.

Hi Todd, no sir, this has a fixed tubular magazine.
Stay safe & have a great day!
