Geissele Automatics Super 42 Tungsten Buffer Weight - AR-15

The Geissele Automatics Super 42 Tungsten Buffer Weight is a precision-machined insert designed to add mass to your existing AR-15 carbine buffer. Drop this single weight into your Geissele Super 42 buffer assembly to convert an H1 weighted buffer into an H2 or H3 configuration, tuning the cyclic mass and recoil impulse of your rifle without buying a whole new buffer.

Constructed from tungsten and steel, the insert is machined to Mil-Spec internal buffer dimensions at 0.5" in diameter and 0.625" long. It drops directly into a standard AR-15 carbine buffer to replace one factory steel weight, increasing overall buffer mass for smoother cycling and reduced bolt bounce across the AR-15/M4 platform.

Installation is straightforward: remove an existing steel weight from your Super 42 buffer and swap in the tungsten insert. No other modifications are required, and each weight is held to Geissele's exacting tolerances for a precise, consistent fit.
