The Geissele Super 42 Braided Wire Buffer Spring and H2 Buffer Combo (Geissele part no. 05-495-H2) pairs Geissele’s three-strand spring with an H2 buffer for AR-15 pattern rifles. Geissele designed the Super 42 spring to improve function and reliability, and its three independent wire strands act as a harmonic damper and energy absorber, as on the German MG42. The spring and the Geissele buffer are designed to work together as a set. It is an upgrade aimed at shooters who want smoother cycling and less recoil spring noise.

Key Specifications

• The spring is the Super 42 braided wire design, built from three independent strands of wire.
• The combo includes an H2 buffer, and the spring and buffer are designed to work together as a set.
• The strands flex separately, acting as a harmonic damper and energy absorber.
• That flex helps displace excess energy, which decreases the chance of spring failure and aids reliability.
• The spring has a 15% stronger average return force than the standard buffer spring, which helps strip rounds from the magazine with a dirty weapon or steel-case ammo.
• Compared to a stock spring, it has a decreased tendency to lose length and force over a given round count.
• It removes the spring reverberation (twang) felt by the shooter through the buttstock.

Frequently Asked Questions

What is in the Geissele Super 42 and H2 combo? The combo is the Super 42 braided wire buffer spring and a Geissele H2 buffer, sold together because they are designed to work as a set.

How is the Super 42 spring different from a standard spring? It uses three independent strands of wire that flex separately, which absorbs energy, resists losing length and force and removes the twang a standard spring can transmit to the stock. Its average return force is about 15% stronger.

Why is a stronger return force useful? Geissele says the added force helps strip rounds out of the magazine when the weapon is dirty or when using steel-case ammunition.
