Questions & Answers
Is this compatible with buffers from vltor A5 system? Expert Answer

According to VLTOR the VLTOR A5 buffers can only be used with VLTOR A5 buffer assembly components. So it will most likely not work with the Geissele Rifle Length Spring, 42 in. However, I recommend contacting VLTOR to confirm.

This Geissele Rifle Length Spring is a rifle length spring designed for rifle length buffer tubes. You would need a carbine length spring.

Helpful Positive Review rifle length spring for A5 system by Jjack, September 28, 2022

Product Info for Geissele Super 42 Rifle Length Spring

The Super 42 Rifle Length Spring for the M-16/AR-15, brings you the performance and user experience improvement of the Super 42 spring for your rifle length buffer tube. This unique spring design uses three independent strands of wire, that acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your M-16/AR-15 rifle more reliable while diminishing the twang sound from the butt-stock. The Geissele M-16/AR-15 Super 42 Rifle Length Spring works with a standard rifle length buffer and buffer tube.image
