Abstract
An armorer tool system for distributing the applied torque over a very wide surface, associated with assembling and disassembling primarily the barrel and the lower receiver extension of an AR platform firearms, independently of the specifications of their barrel extension, lower receiver and upper receiver external features, and magazine well geometry; and methods of using the tools are also disclosed.
Claims11
An armorer tool, adapted to support an AR-15 or an AR-10 platform firearms upper receiver, configured to assemble, and disassemble primarily an upper receiver and a barrel comprising:
- a combination of a flat elongated bar, a plurality of AR-10 bolt carrier well blocks, a plurality of AR-15 bolt carrier well blocks and a locking pin;
- the flat elongated bar comprises a substantially rectangular section having a constant width adapted to match a charging handle well width of the AR-15 or the AR-10 upper receivers,
- the flat elongated bar lengthwise outlines:
- a rear end portion having the height adapted to match a bolt carrier/charging handle well height of an AR-10 upper receiver, a front end portion with a height reduction adapted to match the corresponding height of an AR-15 bolt carrier group/charging handle well, and a middle portion connecting the rear end portion and the front end portion;
- one set of four AR-10 bolt carrier well blocks configured to attach, two on each side, to the rear end portion of the flat elongated bar, each one comprising a circular segment section outlining a flat surface adapted to mate the flat elongated bar and a circular section adapted to mate concentrically the bolt carrier well of an AR-10 upper receiver, and
- one set of four AR-15 bolt carrier well blocks configured to attach, two on each side, to the front end portion of the flat elongated bar, each one comprising a circular segment section outlining a flat surface adapted to mate the flat elongated bar and a circular section adapted to mate concentrically to the bolt carrier well of an AR-15 upper receiver;
- the flat elongated bar front end portion side has four perpendicular through holes configured to attach two blocks on each side to match an AR-15 upper receiver bolt carrier group (BCG) well;
- the flat elongated bar rear end portion side has four perpendicular through holes configured to attach two blocks on each side to match an AR-10 upper receiver bolt carrier group (BCG) well;
- one threaded hole perpendicular to the side of the flat elongated bar, located in the front end portion to attach a threaded pin to secure an AR-15 upper receiver to the tool mating through the spent brass ejection port of the upper receiver, configured to lock together the tool and the upper receiver when the armorer tool extends through the upper receiver and is mated to the barrel extension;
- and one threaded hole perpendicular to the side of the flat elongated bar, located in the rear end portion to attach a threaded pin to secure an AR-10 upper receiver to the tool mating through the spent brass ejection port of the upper receiver, configured to lock together the tool and the upper receiver when the armorer tool extends through the upper receiver and is mated to the barrel extension.
