VLTOR A5 Buffer System Overview

[Cerberus Group]

25 rounds sound like AR10.

So if H3 is great for 7.62, might H2 be best for 5.56 that isn't overgassed?

25 round dump AR-15

I suggest H2s for carbines. For A5 systems the A5H2

Carbines are generally an abusive system, they recoil harder even if gassed properly.

Any reason to use a different buffer spring than the sprinco green rifle spring?

Geissele has a super 42 rifle spring. Guess that could be an option as well.

I don't see a reason to use anything but Sprinco.

Got one that's lasted over 20k and still working as it should.

Im finding the JP polished rifle spring has a bit smoother action than sprinco. Otherwise Sprinco green is the way to go. Super 42 spring at ~$30 is crazy.

..... It's $30....

People put several hundred dollars of cool looking furniture and a way super duper cool trigger on their rifles but crap their pants about a high quality spring that costs about what an oil change at jiffy lube does

Correct me if I'm wrong here, but this seems like the shorter the barrel the more you'll notice the effect?

You'll notice the effect quite a bit with carbine length gas systems, but you'll notice with mid length as well.

It costs 33% more for the Geissle name as does basically all of their products. I dont personally recommend any thing geissle to anyone, except maybe the ssa-e triggers at ~50% off.

You're recommending the H2 over the H3 you mentioned earlier. Why? Both of my guns are carbine length.

He's talking about the A5H3
A5H2 is the "standard" rifle weight and is what most use.

For carbines, an H2 is generally preferred.

I run A5H2 in my middy truck gun now.
Pretty smooth shooter.

Yep, bought an a5h3 just in case i needed it, never used it. All my rifles run a5h2 buffers.

As been said above...to start I recommend an H2 for carbine length gas systems and go from there.

Thank you both. I know next to nothing about these things. I appreciate the info.

 

[titsonritz]

I use a blue Sprinco spring and Colt H2 buffer with carbine RE and green Sprinco spring and Vltor A5H2 buffer with the A5 RE. I've used Vltor, BCM and Magpul tubes.

Ok, here we go...

I have an 11" gun that throws cases between nearly 12 o'clock and 1:30-2. It has the "normal" H buffer in it. Spring unknown.
Curt's is the local AR parts place. I went in last weekend looking for an H2 buffer, or maybe even an H3 and planned to buy a spring of known quality at the same time. Talking to the owner, they are our of buffers! Then he pulls this thing out and says that it's an H3 equivalent. To me it looked like a complicated answer to a simple problem, but I decided "WTF?" and bought it.
I can get pretty impulsive and figured out at worst I would find out why the schmarter ones here recommend what they do. Ya only get experience one way...
I was able to take the gun out the very next day to see how it worked and was pretty disappointed to find out that the new "thingie" didn't change the ejection pattern one bit. It did take away the sproing noise out of the butt. Don't have a clue if it changed the recoil impulse at all, as I think these are easy shooting guns. Do any of you have an opinion on what I bought? Not the fact it didn't solve my issue, but are these things worth a damn or is it a gimmick?
I've looked at the Vltor A5 and have a couple of questions before I order one.
Why wouldn't I just put rifle parts on my gun instead of the A5?
No matter what, my gun seems to be over gassed with ah H buffer. What weight would you guys recommend I buy?

Yeah, but how did the gun sound?

 

[Steel Head]

An a5, rifle or heavy carbine buffer won't fix heavily over gassed, think of it as a fine tune.

What you need is a coarse adjustment, adjustable gas block or similar gas restriction method.

That said I run A5 or rifle buffer/spring in everything I can.
They are superior to carbine in my opinion.

I think they're gimmick...but then I tend to stick with tried and true tested engineered buffers and springs.

I'm not into adjustable gas blocks, as I've seen many disintegrate over time from the gas. If the adjuster screw isn't turned now and then, they will carbon themselves in place, and will no longer be adjustable.

Another thing, there are variables that factor into the ejection pattern...just because it's dropping the cases at 1-2 o'clock, doesn't mean its over gassed. Buffer and/or spring rate along with extractor shape and tension, strength of ejector spring and even the shape of the ejection port and deflector can influence the pattern.

How would I differentiate between being over gassed and other issues?
