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

Somebody tell G to make a rifle length braided wire spring so we can test it in the A5RE.

I don't think it would work with the a5 buffer

Interesting, if it were the correct length, why not?

Because the spring is thicker. The carbine one doesn't work with carbine buffer either. It's a proprietary buffer that's smaller in diameter to compensate for the spring.

Ah, gotcha. Didn't notice that.

Thanks to all for responding. So basically the Geissele spring will last longer but doesn't improve reliability or reduce bolt bounce?

It's a little stiffer than mil-spec, which is good. I find that mil-spec springs don't get it done for me in my AR's.

From your video on another thread here. It may be helpful to look into what others are doing without requiring the need to increase L1 action spring tension to this point. That and using the FA without needed results. There are some issues here that are not inline with others in use.

Dunno what thay would be. All testing I've seen shows inadequacy of the milspec spring. It's about 400% less consistent in cyclic rate, too, due to variance when stripping rounds in full auto fire. It's just anemic.

I think those are just problems associated with the carbine length systems in general. You have a weaker spring combined with half the mass in the buffer. I've been told it's something to do with the compression rate, but I'm pretty vague on that term.

Looks like I will be going with the A5.
