    PACKAGE DEAL: 2 ea. .50 BMG Barrels, Plus An Electric-Fired Single-Shot Action. $1250, OBO. (The Inventor/Owner is elderly and a motivated seller)


    —All Items are bundled together and will not be sold separately.
    —Includes all work product, drawings, the inventor's "release", and, possible phone conversations with Inventor.

    This ad offers the complete package/makings of a unique, working, D.I.Y. .50 BMG Bench Gun.

    —When assembled it is a working prototype. This prototype has been fired approximately 10 times. Assembly is simple.

    NOTE #1: The barrels have been lathe-modified from mil. surplus M2 machine gun barrels (.50 BMG).

    NOTE #2: The inventor created the single-shot action to be actuated/fired by an electric charge stored in an electric Capacitor Bank.

    SHORT BARREL: ~29 inches; ~14 pounds; largest diameter = ~1.7 inches
    LONGER BARREL: ~43.8 inches; ~20 pounds; largest diameter = ~1.8 inches

    Either the SHORT BARREL or the LONGER BARREL can be used.

    —The unique (one-of-a-kind) electro-mechanical Action is screwed onto the original M2 barrel threads using a suitable washer thickness between them to create correct 'head-spacing'.

    The SAFETY is an electric switch, and/or the easily disconnected electrical connectors.

    The C-BANK is charged quickly by 120VAC from the electric grid, or by a 12 volt battery input to the included 120VAC inverter. A charged vehicle's battery or a charged small garden tractor battery is quite sufficient for many shots.

    The TRIGGER (an electric switch) causes the charged C-Bank to discharge rather instantaneously. That is, the C-Bank discharges powerfully to actuate an electric solenoid in The Action which then mechanically transfers energy to THE ACTION'S firing pin to fire the .50 BMG round.

    --THE First Photo shows: both barrels with a measuring tape between them.
    --THE Second Photo shows: The Action attached to one of the barrels
    --THE Third Photo shows: the main Action parts:
    A) The Action's Main Body,
    B) The Breech Transfer-Pin Assembly,
    C) The Solenoid, and,
    D) The Solenoid's Ram, ...there in the right end of the solenoid.
    NOT SEEN is the electrical equipment (the C-Bank, etc.) and the various work product items which led to the final design..., and the documentation.

    .50 BMG - Wikipedia
    .50 BMG - Wikipedia
    The .50 Browning Machine Gun is a cartridge developed for the Browning .50 caliber machine gun in the late 1910s.

    Interesting:
    —The .50 BMG is a scaled-up 30.06 Cartridge
    —Typical bullet weight is ~1.5 ounces! = ~40-50 grams! = ~600-750 grains!
    —The .50 BMG cartridge/bullet creates approximately 12-15,000 foot pounds of kinetic energy.
    —The .50 BMG bullet travels ~3000 feet per second.

    OP is the action serialized? It could be a hard transfer item without it.

    Also, do you just ratchet strap it to a table, or did you craft a mount for the barrel to sit in for firing?

    The "Action" was invented in the process of exploring the possibility of using electricity to electro-mechanically fire a gun. It is/was a laboratory R&D project and is not presently serialized.:)

    No it’s not. You can sell a firearm you made to another person. It’s highly recommended that it has some sort of serial number, a manufacturer name and a location it was made engraved or stamped into it before doing so.
