Drop-in fixed magazine
First Claim
1. A rifle comprising:
- a lower receiver defining a magazine well having a selected cross sectional profile;
the magazine well having an upper end and a lower end;
an upper receiver removably pivotally connected to the lower receiver to pivot between a first closed position in which at least a portion of the upper receiver overlays the upper end of the magazine well and a second open position in which the upper end of the magazine well is exposed;
a magazine having a body with a cross sectional profile sized to be slidably closely received in the magazine well;
the magazine having an upper end portion having a lateral protrusion extending beyond the cross sectional profile; and
the protrusion being adapted to contact a selected portion of the lower receiver adjacent to the upper end of the magazine well when the magazine is received within the magazine well, such that extraction of the magazine from the lower end of the magazine well is prevented, and such that the upper receiver must be moved away from the lower receiver to enable removal of the magazine from the lower receiver.

Abstract
Drop-in fixed magazines have a tubular body defining an elongated passage and having a lower end and an upper end, the body having an exterior surface that closely fits the profile of the magazine well, and the body including protrusions of the upper end extending laterally beyond the profile. The protrusions may engage a surface of the rifle to limit downward movement of the body within the magazine well. The rifle may have to be operationally disabled to enable the magazine to be installed into or removed from the magazine well. The rifle may include an upper receiver and a lower receiver, the lower receiver may have a top, and the upper receiver may have to be removed from lower receiver, thereby exposing the top of the lower receiver, in order to enable the magazine to be installed into or removed from the magazine well.
