Abstract
A flex-plate adapter for a takedown firearm has front and rear sections. The rear section includes adjustment screws to change the gap between the front and rear sections. Guide pins are included for assuring proper alignment between the front and rear sections. The adjustable gap between the front and rear sections of the flex-plate adapter provides compensation for thread wear. A magazine cutoff provides a manual cutoff for retaining ammunition in the magazine whether the rifle is assembled or disassembled. A cutoff lock prevents the accidental movement of the magazine cutoff.
Claims14
An apparatus for barrel adjustment in a takedown firearm, the apparatus comprising:
- a front section and a rear section, a distance between a forward surface of the rear section and rearward surface of the front section being adjustable, a forward surface of the front section being adapted to abut a rearward surface of a fore-end of a firearm, a rearward surface of the rear section being adapted to abut a forward surface of a receiver of the firearm;
- an upper opening extending through both sections and adapted to receive a rear portion of a barrel;
- a lower opening extending through both sections and adapted to receive a rear portion of a magazine;
- and
- at least one pin for maintaining alignment of one of the sections to the other of the sections, the pin extending from one of the sections and being received by a socket in the other of the sections.

- a front section and a rear section, a distance between a forward surface of the rear section and rearward surface of the front section being adjustable, a forward surface of the front section being adapted to abut a rearward surface of a fore-end of a firearm, a rearward surface of the rear section being adapted to abut a forward surface of a receiver of the firearm;
- an upper opening extending through both sections and adapted to receive a rear portion of a barrel;
- and
- at least one pin for maintaining alignment of one of the sections to the other of the sections, the pin extending from one of the sections and being received by a socket in the other of the sections;
- and wherein
- the distance is adjusted by at least one screw which connects the sections to one another.
In a takedown firearm having a fore-end which carries a barrel and a magazine and is detachable from a receiver, the improvement comprising:
- a front section and a rear section, a distance between a forward surface of the rear section and rearward surface of the front section being adjustable, a forward surface of the front section abutting a rearward surface of the fore-end of the firearm, a rearward surface of the rear section abutting a forward surface of the receiver of the firearm;
- an upper opening extending through both sections and receiving a rear portion of the barrel;
- a lower opening extending through both sections and receiving a rear portion of the magazine;
- at least one pin for maintaining alignment of one section to the other, the pin extending from one of the sections and being received by a socket in the other of the sections;
- at least one screw which connects the sections to one another;
- and
- a magazine cutoff mounted to one of the sections that is selectively movable to at least partially obstruct the lower opening and to selectively prevent ammunition stored in the magazine from passing through the lower opening.
A method of assembling a takedown firearm having a barrel, a fore-end, and a magazine, the method comprising:
- (a) providing an adapter having front and rear sections;
- (b) inserting the barrel into an upper opening extending through both sections;
- (c) inserting the magazine into a lower opening extending through both sections;
- (d) adjusting screws connecting the sections to one another to select a distance between the sections and to select a planar orientation of the sections relative to each other;
- and
- (e) securing the barrel to the receiver, abutting a rearward surface of the fore-end of the firearm with the front section, and abutting a forward surface of a receiver of the firearm with the rear section.
