Geissele Tungsten Buffer Weight for AR-15

The Geissele Automatics Tungsten Buffer Weight (brand part no. 04-246-F) is a dense buffer weight built to add mass inside a standard AR-15 buffer tube. Geissele uses tungsten, a significantly denser material than the steel weights found in a standard buffer, to increase reciprocating mass without changing the buffer’s outer dimensions. Added buffer mass slows bolt carrier velocity and smooths out the cycling impulse, which reduces felt recoil and muzzle movement between shots. It is a straightforward internal upgrade for shooters tuning a rifle’s recoil impulse for competition, precision work, or general shootability.

Key Specifications

• Tungsten Construction is significantly denser than a standard steel buffer weight.
• Increased Reciprocating Mass slows bolt carrier velocity for smoother cycling.
• Reduced Felt Recoil comes from the smoother, slower cycling impulse.
• AR-15 Buffer System Compatibility fits standard AR-15 buffer tubes.
• Drop-In Sizing matches standard buffer weight dimensions for simple installation.

Frequently Asked Questions

What does a tungsten buffer weight do? It adds mass to slow bolt carrier velocity and smooth the cycling impulse.

Why tungsten instead of steel? Tungsten is significantly denser, adding more mass in the same space.
