The devices can include mechanisms such as a crank mechanism, guide rails, and stop plate to enable simplified disassembly and reassembly of a firearm. ## Claims ### Claim 1 A firearm disassembly and/or reassembly device, comprising: a base; first and second guiderails on said base; and a crank device on said base, said crank device comprising: a crank stand; a crank; a push mechanism; and a crank shaft between said crank and said push mechanism, said crank shaft connected to said crank stand at a connection point; wherein said crank is operable to move said push mechanism; and wherein an angle of said crank shaft between said crank and said push mechanism is adjustable by adjusting a location of said connection point on said crank stand. ### Claim 2 (depends on 1) The device of claim 1, wherein said first and second guiderails are substantially parallel to one another. ### Claim 3 (depends on 1) The device of claim 1, further comprising a stopper on an end of said base opposite said crank device. ### Claim 4 (depends on 1) The device of claim 1, wherein said crank device further comprises a crank base, wherein a stationary position of said crank base relative to said base is adjustable. ### Claim 5 (depends on 1) The device of claim 1, wherein said crank shaft angles downward between said crank and said push mechanism. ### Claim 6 (depends on 1) The device of claim 1, wherein said first and second guiderails extend on said base in a first direction away from said crank base; and wherein operation of said crank is configured to move said push mechanism in said first direction such that said push mechanism moves over said first and second guiderails. ### Claim 7 (depends on 1) The device of claim 1, further comprising a plunger, said plunger configured to move over said first guiderail toward said second guiderail. ### Claim 8 (depends on 7) The device of claim 7, wherein said plunger is on a plunger stand movably attached to said base. ### Claim 9 (depends on 8) The device of claim 8, wherein said plunger stand is rotatable between an upright position and a downward position. ### Claim 10 (depends on 8) The device of claim 8, further comprising a plunger rail on said base, wherein said plunger stand is attached to said plunger rail. ### Claim 11 (depends on 10) The device of claim 10, wherein said plunger rail runs in a first direction on said base, and wherein a position of said plunger stand on said plunger rail is adjustable along said plunger rail in said first direction and in a second direction opposite said first direction. ### Claim 12 (depends on 11) The device of claim 11, wherein said plunger stand is rotatable about said plunger rail between an upright position and a downward position. ### Claim 13 (depends on 1) The device of claim 1, wherein said first and second guiderails are on a top side of said base, and further comprising a base stop extending downward from said base. ### Claim 14 (depends on 1) The device of claim 1, further comprising a stopper on an end of said base opposite said crank device; wherein said base, said first and second guiderails, and said stopper are configured to hold a slide of an inverted firearm therebetween, said firearm comprising said slide and a frame; wherein said crank is operable to move said push mechanism such that said push mechanism pushes said frame forward, while said stopper maintains said slide. ### Claim 15 (depends on 1) The device of claim 1, wherein said base comprises first and second portions with a hinge therebetween, said crank device on said first portion and said first and second guiderails on said second portion, wherein said base is foldable at said hinge. ### Claim 16 (depends on 1) The device of claim 1, wherein said crank stand comprises two or more indexing positions, and wherein said connection point is adjustable among said two or more indexing positions. ### Claim 17 (depends on 16) The device of claim 16, wherein said crank stand comprises a sawtooth pattern forming said two or more indexing positions. ### Claim 18 (depends on 1) The device of claim 1, wherein the location of said connection point on said crank stand is adjustable over a continuous range of positions. ### Claim 19 (depends on 1) The device of claim 1, wherein said crank is operable to move said push mechanism toward or away from said first and second guiderails. ### Claim 20 A firearm disassembly and/or reassembly device, comprising: a base; first and second guiderails running in a first direction on said base; a plunger rail running in said first direction on said base; a plunger attached to a plunger stand, said plunger stand movably attached to said plunger rail, wherein a position of said plunger stand on said plunger rail is adjustable along said plunger rail in said first direction and in a second direction opposite said first direction, and wherein said plunger stand is rotatable about said plunger rail between an upright position and a downward position; and a crank device on said base, said crank device comprising: a crank; a push mechanism; and a crank shaft between said crank and said push mechanism; wherein said crank is operable to move said push mechanism.
