Hard to Find Gun Parts

Most gun parts are easy to buy. The ones that are not — the discontinued, the obsolete, the parts for a model nobody has manufactured in forty years — are what Jack First has specialised in since 1954.

What makes a part hard to find

A part usually becomes difficult to source for one of a few reasons. The model went out of production and the factory stopped supporting it. The part changed mid-run, so the component that fits a 1962 example will not fit a 1974 one carrying the same model number. The gun was an economy model that nobody thought worth keeping parts for. Or the maker itself no longer exists.

Any of these will stop a general retailer being able to help. All of them are ordinary here.

What we stock

Our inventory runs to roughly 15,000 individual parts across more than 1,000 model categories, covering firearms built from the 1880s through to modern production. That includes original factory parts, good used parts pulled and inspected, and reproductions manufactured to original specifications where nothing original survives.

Manufacturers covered include Remington, Winchester, Marlin, Smith & Wesson, Colt, Browning, Savage, Mossberg, Stevens, Ruger, Beretta, High Standard, Iver Johnson, Harrington & Richardson, Rossi, Dan Wesson, Thompson/Center and many smaller and defunct makers.

Finding the right part

Parts are organised by manufacturer, then by action type, then by model and production period — because with older firearms the production period is often what decides whether a part fits. If you know your model and roughly when it was made, you can usually narrow to the right group in two or three clicks.

If you have a Jack First part number, searching that number directly will take you to the item.

Why the organisation matters

A catalogue this size is only useful if it is sorted properly. Where a model changed significantly during its run, we keep the production periods in separate groups rather than lumping them together — the Marlin 336 and 1894, the Winchester Model 94 either side of 1964, and the Smith & Wesson frames across their production eras are all handled this way. It makes the catalogue larger, but it means what you find is what fits.

Browse by manufacturer to begin, or search a model or part number directly. If your firearm dates from the late nineteenth or early twentieth century, see our antique gun parts for the models and eras we cover.
