Geissele Super 42 Tungsten Buffer Weight 04-246-F

Geissele Super 42 Tungsten Buffer Weight 04-246-F is a single tungsten weight designed to replace one steel weight inside a Super 42 carbine buffer, bumping the buffer up one weight class per weight added.

To change a Geissele H2/H3 buffer weight setup from a base H1 assembly, the buffer needs to be disassembled and reassembled, replacing the standard steel weights with the correct number of tungsten weights. Since the base Super 42 buffer is already H1, adding one tungsten weight makes it an H2, and adding two makes it an H3 — each weight raises the classification by exactly one step.

This Geissele Super 42 Buffer Weight relies on tungsten's density, nearly 2.5 times that of steel, to pack more mass into the same physical space a standard steel weight occupies. That density lets builders fine-tune total buffer mass without changing buffer length or buying an entirely new buffer body.

Key Features:

• Single tungsten replacement weight
• Drop-in fit for Geissele Super 42 buffer assemblies
• Increases buffer weight class by one step per weight
• Tungsten density ~19.3 g/cm³, nearly 2.5x steel
• Compatible with H1, H2, and H3 Super 42 buffers
• Bevel-edged for a precise fit inside the buffer body
• Affordable alternative to buying a full replacement buffer
• Made in the USA

This Geissele buffer weight gives builders a precise, incremental way to tune felt recoil and cycling without over-buffering the gun into short-stroking territory.
