i use the ar15 version: http://www.davidtubb.com/ar15-bufferspring and i use the 308 version for my 308s.
It’s a rate stabilizing spring. It also ensures that during the first 1/8” to 1/4” of carrier movement (when unlocking occurs) that the stack of internal weights applies full mass to the rear of the carrier. It turns every milspec carrier into one of those fancy weighted carriers, but with no downside.
Now, shooting from a stable position and not a lot of up-angle and it might not make a ton of difference in terms of feel.
My brass always stacks tighter on the ground when I have the spring in place. I’ve tried it both ways as well.

Theoretically it’s supposed to give you less felt recoil ala rifle type buffer system.
Just as markm stated below.
I never used the flat wire springs. But the A5H2 I used was pretty meh.
This is what I currently use in all of my non-SBR rifles and they work well. For the SBR’s, they get the H3.
BufordTJustice, I read your entire thread about the A5 and LMT e-carrier and I have a question. Rather than necro-post I'll ask here. With the A5H4 and a standard rifle spring, and with the carbine aimed straight up, does it still easily strip the first round from a magazine when released with the BHO?
Yes.
With the caveat that my guns all have a few K rounds through them. So they are broken in.
In a new upper, with a new parkerized carrier, you may have some issues with that specific test until you get a few hundred rounds. But only in the vertical position.

Thanks. I would like to polish my carrier rails and sides of gas key the way you did. Is jouler's rouge by hand followed by a naked felt wheel at low speed, as described in post #97 of https://www.m4carbine.net/showthread...59#post1436559 the method you recommend still?
Also, do you still use and recommend the V Seven cam pins?

Yes and yes.
It’s just skipping the break in period. Wear acceleration. Used it on dozens of builds.
The V7 cam pin remains my favorite, but the Lantac pin (which I also use) is excellent as well. Preference, in slight degree, goes to V7, but both are excellent.

What is the internal stroke of the A5 buffer, i.e. how far can the buffer weights move within the buffer body?
