Complete your U.S. recoilless rifle restoration with this small, easily lost component that serious collectors are always hunting for. This New Old Stock 57mm M18 Trigger Safety Spring is an original U.S. military part for the M18 57mm recoilless rifle, preserved as unissued surplus and identified by Part Number 7229526. For restorers, armorers, and collectors, pieces like this matter because the small control-group parts are often the first to disappear and the hardest to replace correctly.

The M18 recoilless rifle was one of the most important lightweight direct-fire support weapons fielded by the U.S. Army at the end of World War II and in the Korean War. Designed as a 57mm shoulder-fired recoilless rifle, it gave infantry units a portable weapon capable of firing HEAT, HE, smoke, and training rounds against armor, bunkers, and field fortifications. Its relatively light weight and compact size made it especially useful where heavier anti-tank guns were impractical. That wartime and postwar service history is exactly why original M18 components remain so desirable today.

This trigger safety spring is part of the M18's trigger and safety mechanism, one of the small but essential parts of the weapon’s control system. On any historic weapon restoration, major assemblies may get the attention, but it is the correct detail parts that determine whether the finished piece is truly right. A proper original spring like this is the kind of component that helps preserve both the mechanical logic and the historical integrity of an M18 project.

What makes this example especially appealing is that it is offered as new old stock. That means it was manufactured for military service use but remained unissued, making it a far better choice for restoration than a worn or improvised replacement. Original NOS parts like this are ideal for anyone who wants to keep a build as authentic as possible.

This piece is also attractive beyond restoration work. It is a strong addition to any collection of U.S. recoilless rifle parts, ordnance spares, or military gunsmithing components. For museums and advanced reference collections, having the correct original small parts on hand is often just as important as locating major assemblies.

Whether you are restoring a 57mm M18 recoilless rifle, building out a reference collection of original U.S. anti-tank weapon components, or simply setting aside rare spare parts for future projects, this New Old Stock M18 Trigger Safety Spring is exactly the kind of original detail part that is worth securing while it is still available.
