Geissele Automatics Super 42 AR-15 Tungsten Buffer - Carbine

The Geissele Automatics Super 42 Tungsten Buffer Weight lets AR-15 owners fine-tune their existing buffer's mass without replacing the whole assembly. Built as a compact, high-density tungsten slug, this drop-in weight adds precise mass to a compatible buffer body for shooters dialing in recoil impulse and cycling reliability.

Features:

• 1.44 oz per individual slug
• High-density tungsten construction
• Raw/stainless steel finish
• 0.50" diameter, 0.625" length
• Internal drop-in replacement, cylindrical design
• Compatible with AR-15/M4 platform buffer bodies
• Includes one individual buffer weight

Tungsten's high density lets this weight add significant mass in a small physical footprint, giving shooters a way to fine-tune buffer weight without sourcing an entirely new H1, H2, or H3 buffer. Because it's a drop-in internal component, it works inside a compatible existing buffer body rather than replacing it outright, making it a straightforward way to test different weight configurations for a specific rifle, ammunition, or suppressor setup.

Founded in 2004 by Bill Geissele in Pennsylvania, Geissele Automatics built its reputation on precision AR-15 triggers before expanding into rail systems, gas systems, and buffer components. Their Super 42 line reflects that same attention to detail applied to recoil system tuning.
