Aluminum Spacers 1/2in ID x 1/4in Long

The Aluminum Spacers 1/2in ID x 1/4in Long are precision-engineered components designed for firearm assembly and tactical equipment construction. These spacers are essential for applications requiring precise standoff distances, making them suitable for optic mounting systems and rail accessories.

Constructed from lightweight aluminum, these spacers provide an excellent strength-to-weight ratio without adding unnecessary bulk. The 1/2-inch inner diameter is compatible with standard fastener sizes used in AR-platform assembly, while the 1/4-inch length ensures controlled spacing for precision applications. The aluminum material also offers corrosion resistance in field conditions.

These spacers are ideal for armorers building custom tactical rifles and shooters installing aftermarket accessories. Their standardized dimensions ensure compatibility across various OEM and aftermarket components, making them a reliable choice for precision assembly work. Installation is straightforward—simply position the spacer on the fastener shaft before final assembly.
