Geissele Super 42 BW Spring and BufferH1

Geissele Super 42 BW Spring and Buffer H1 The Geissele Super 42® spring and H1 buffer are designed to enhance the performance and reliability of the AR-15 rifle. The spring consists of three independent wire strands that act as a harmonic damper and energy absorber.

This design reduces the risk of spring failure and improves the operational reliability of the firearm. The spring is 15% stronger than the standard model, which is particularly beneficial for dirty firearms or when using steel-cased ammunition.

The product is only compatible with carbine-length buffer tubes and is not recommended for use with 300 Blackout sub-caliber ammunition.
