Geissele Automatics Super 42 Tungsten Buffer Weight - 04-246 - UPC 854014005915
Product Description
The Geissele Automatics Super 42 Tungsten Buffer Weight (04-246) is a precision-machined tuning component engineered to allow shooters to customize and optimize the buffer weight configuration of their Geissele Super 42 Buffer and Spring assemblies. High-density tungsten weights allow users to easily convert a standard carbine buffer (H1) into heavier H2 or H3 configurations, providing tailored reciprocating mass to smooth out bolt carrier cycling and mitigate felt recoil.
Ideal for tuning short-barreled rifles (SBRs), suppressed AR-15 platforms, or over-gassed carbines, replacing lighter steel weights with Geissele tungsten weights increases bolt dwell time and delays unlock. This reduces bolt bounce, lowers wear on internal fire control components, and softens the recoil impulse for faster target re-acquisition during rapid-fire strings.
Precision-ground to Geissele's exact dimensional tolerances, the 04-246 tungsten weight fits seamlessly into Super 42 carbine buffer housings. Whether fine-tuning gas system physics for dedicated suppressor use or adjusting ejection angles, this modular tungsten weight delivers duty-grade reliability and modular versatility for the AR-15 platform.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits inside Geissele Super 42 Carbine Buffer bodies. Note: Designed specifically for Geissele Super 42 buffer bodies; verify internal housing dimensions if attempting installation in standard Mil-Spec carbine buffers.
- Verify the firearm is completely clear, safe, and unloaded before servicing buffer assemblies.
- Drive out the rubber bumper roll pin at the rear of the Super 42 buffer body using a punch, then slide out the internal weights and rubber spacer pads.
- Swap standard steel weights with tungsten weights to achieve your desired buffer weight setup (H1 = 1 Tungsten / 2 Steel, H2 = 2 Tungsten / 1 Steel, H3 = 3 Tungsten), reinsert internal spacers, and secure with a new roll pin.
