Add an original, hard-to-find U.S. aircraft cannon component to your collection or restoration project with this New Old Stock 20mm M39A2 Striker Extractor for Left-Hand Feed. This is an authentic surplus part from the M39A2 20mm revolver cannon family, preserved as unissued old stock and intended for the left-hand slide assembly.
For serious restorers and collectors, these small internal parts are often the hardest pieces to locate. Large visible components get saved. Specialized handed-feed parts like this one are usually the first to disappear. That makes an original left-hand M39A2 striker extractor especially desirable for anyone trying to complete a correct gun, build a proper display, or stock rare spares for future restoration work.
The M39A2 and Left-Hand Feed Configuration
The M39A2 is part of the long-serving U.S. 20mm M39 revolver cannon family, a single-barrel aircraft autocannon developed from postwar revolver-cannon concepts and widely associated with Cold War U.S. fighter aircraft. The M39A2 became one of the best-known service variants and remained in use on aircraft such as the Northrop F-5. The system’s compact revolver design, 20×102mm chambering, and aircraft-friendly layout made it one of the classic American aircraft guns of the era.
A key detail for restorers is that the M39A2 family was produced in left-hand and right-hand feed configurations, depending on the installation. Aircraft gun bays and mounting arrangements often dictated feed direction, so handed parts were critical to building a correct system. That is exactly why components like this left-hand striker extractor matter. They are not generic internals. They belong to a specific feed-side arrangement and to the left-hand slide assembly used on left-feed guns.
About the Striker Extractor
This striker extractor is one of the specialized components within the left-hand slide assembly of the M39A2. On a high-speed aircraft cannon, parts in the slide and extraction system play an important role in the gun’s firing and cycling sequence. In restoration terms, this is the kind of detail part that can stop a project cold if it is missing.
This example is offered as new old stock, meaning it was manufactured for military service use but remained unissued. That gives you:
Why This Part Matters
Anyone can find broad descriptions of the M39A2. Finding the correct internal parts is another story. Left-hand feed components are especially important because aircraft gun systems were often built as mirrored or installation-specific assemblies. If you are restoring a proper left-hand feed M39A2, this is exactly the sort of part you want to have on hand.
It is also a strong collectible in its own right. Even outside a full gun restoration, original M39A2 internals are desirable for:
Condition
This item is new old stock. As with most long-stored military surplus parts, you should expect typical storage wear consistent with age and arsenal handling. Because it remained unissued, it is a much more attractive option than a worn service take-off part when originality matters.
Ideal For
This part is an excellent fit for:
Approx length 3", Approx width 1.5", Approx height .75", Approx weight .5lbs.
