(i) a proximal end;
(ii) a distal end;
(iii) a deck extending between the proximal end and the distal end, wherein the deck is configured to support the tissue of a patient;
(iv) a longitudinal slot defined in the deck extending from the proximal end toward the distal end;
(v) staple cavities arranged in longitudinal rows;
(vi) staples removably stored in the staple cavities;
(vii) a lock configured to releasably lock the staple cartridge into the channel; and
(viii) a projection extending above the deck, wherein the projection comprises a crush rib configured to plastically deform against an anvil, the crush rib extending from the projection to create a snug interface between the staple cartridge and the anvil; and

(c) the anvil, comprising:
(i) staple forming surfaces configured to deform the staples when the staples are ejected from the staple cartridge during a staple firing stroke;
(Ii) a proximal end;
(iii) a distal end; and
