GEISSELE SPR 42 BRD WIRE BFR/SPR CMB

The Geissele SPR 42 BRD WIRE BFR/SPR CMB by Geissele Automatics is engineered to enhance the performance and durability of AR-15 style rifles. This buffer spring and buffer combo features a distinctive design with three independent wire strands, which work collectively to absorb and dissipate energy more effectively than traditional single-strand springs. This multi-strand construction reduces spring fatigue and extends service life by minimizing length and force loss over extended use.

Additionally, the SPR 42 spring mitigates the common issue of spring reverberations, often experienced as an audible and tactile "twang" through the rifle’s buttstock. The spring provides approximately 15 percent greater return force compared to standard buffer springs, promoting more reliable cycling, especially when using steel-case ammunition or operating with a firearm in less-than-ideal conditions. This model includes an H1 buffer assembly and is designed specifically for use with compatible buffer tubes, excluding rifle length or A5 configurations. The Geissele SPR 42 buffer spring combo is a practical upgrade for shooters seeking improved reliability and smoother operation in their AR-15 platform.
