1. A bone graft material delivery system, comprising:
a hollow tube adapted to receive bone graft material, the hollow tube having: a proximal portion;
a distal portion with at least one opening therein; and
a breech area therebetween, the breech area configured to be opened and closed;
a plunger configured for urging bone graft material from the proximal portion through the distal portion and outwardly through the at least one opening of the distal portion, wherein the plunger has at least one engagement feature; and
a trigger configured to engage the at least one engagement feature of the plunger and being operable to advance the plunger toward the distal end of the hollow tube;
wherein the proximal portion is securely interconnected to the distal portion along a longitudinal axis of the hollow tube; and
wherein, when the breech area is open, an interior volume of the proximal portion is exposed to allow for loading of bone graft material therein, a hollow interior of the hollow tube having a generally rectangular cross-section.
