Vltor A5 vs. Geissele Super 42, which is better?

[HansTheHobbit]

I just installed one on a BCM carbine length gas 16" and it made a noticeable difference in recoil and smoothness compared to a BCM mid-length gas 16" with a standard H buffer and spring. I only shot about 60 rounds with it but I was impressed. This is, of course an "example of one" and will require much more use to make a definitive opinion but it looks promising. As always, YMMV. No opinion on the A5 system as I don't have one.

Thanks! Now if only Geissele would make their spring in a rifle length version, preferably that worked with standard buffers.
