BudsGunShop.com - mount a red dot on it

Ken, this is not drilled & tapped. I actually own this gun, it has a 3/8 dovetail rail. You will need this adapter to mount a red dot >>>>> budsgunshop.com/product_info.php/products_id/132553/ncstar+adapter+3+8+dovetail+to+picatinny+rail+black ......p.s. I just watched the video James linked to and it says nothing about being drilled & tapped.

The Stoeger M3K is a well made, reliable, dependable shotgun. And its made in the same factory as Beretta, and Benneli, and its only about $100 more then the black aces, in stock here

Yes it is drilled and tapped for a rail.
James Reeves at TFBTV did a torture test on this shotgun and it was no longer functioning after 416 rounds.
Good honest review here
