The Geissele Super 42 Braided Wire Buffer Spring and H3 Buffer Combo is a spring and buffer set for AR-15 pattern rifles with carbine-length buffer tubes (brand part no. 05-495-H3). Geissele Automatics builds the spring from three independent strands of wire that flex separately and act as a harmonic damper. The result is a spring that returns the carrier with about 15 percent more average force than a standard buffer spring and takes the twang out of the buttstock. The kit includes an H3 buffer assembly. It suits builders who want a reliability upgrade for a carbine-length AR-15.

Key Specifications

• The spring uses three independent strands of braided wire, which flex separately to absorb excess energy.
• Average return force is about 15 percent stronger than the standard buffer spring.
• The stronger return force helps strip rounds from the magazine when the rifle is dirty or running steel-case ammunition.
• Compared with the stock spring, it has a decreased tendency to lose length and force over a given round count.
• The design removes spring reverberation, the twang that shooters hear and feel through the buttstock.
• An H3 buffer assembly is included, so the spring and buffer come as a pair.
• The set is made for AR-15 pattern rifles, the platform Geissele designed it around.
• It fits carbine-length buffer tubes, the standard receiver extension on most AR-15 carbines.
• It is not compatible with rifle-length or A5 buffer tubes and receiver extensions.

Frequently Asked Questions

What buffer is included with the Super 42 spring? The combo includes an H3 buffer assembly.

What does the braided wire design do? The three independent wire strands flex separately, which absorbs excess energy, reduces spring reverberation and helps the spring hold its length and force.
