Heavy Buffers... technical questions

[mustangfreek]

Unless your gun is really over gassed or you're shooting suppressed, I think this obsession the last few years with buffers is gotten out of control.

I 100% agree with that..every forum there’s always a thread on this subject of some sort..

But there’s also been so many advancements it makes ya wonder what does work, maybe better?

I’ve been eyeballing those armaspec srs setups.. but that’s another thread..

You said it. Of course it's gonna drive Alamo's OCD batshit, so grab some more Orville Redenbacker's.

Lmao.....I agree.....sorry Alamo......

It seems paradoxical to me to want to take better care of your rifle by spending more on the recoil system, but then feed it questionable ammunition. Sure, it's not corrosive, but we all know China loads everything with lead, or carfentanil. Why run crap through your gun's digestive system? What's in that faceful of eastern bloc or commie Red "gas"? Your rifle can't wear a gaiter!

[Aragorn]

Too much overthinking here. Adjust your gas or buffer weight to lock back, unsupported, unsuppressed, with the weakest ammo you intend to run. Then it'll run anything you feed it suppressed or not.

They got everything EXCEPT plain vanilla. It's sort of like a titanium castle nut or some gimmick like that, except when it comes to buffers they actually do stuff inside the gun and weight does matter when it comes to function. I just don't know how much leeway there is here. I will probably just pull the one out of my current SBR and put it on a scale and find out which one of those listed above is closest to it. It's not like I will be fawning over a cool looking buffer once the rifle is together.

You sound like you're building a lower for the exact same caliber you already have, which I'm sure is not the case. You also have to consider that .300 and 9 mm have a softer recoil than 5.56. If you're building this for your B.O. upper, I think you will be surprised at how well it runs without any fiddling with the recoil system.

If you need to fart around with it that badly, take the upper apart, clean, lube and re-torque everything.

Or you can buy an adjustable buffer and replace the discs with tungsten shot for the most precise weight for custom handloads*.

*I can't name anybody that does this, probably because that minute a level of tuning returns no advantage.

Having a buffer that’s too heavy can increase recoil impulse and cause issues with the next round being picked up.

There’s no way to know for sure without testing the various weights, like if you skipped from Carbine to H3, if the H or H2 would do the trick.

It may be a fun little experiment just to see ejection pattern shift and how the rifle responds but it will be more for satisfying a curiosity than anything else if the rifle current functions fine. But who knows, it could end up being more than that in terms of your rifle running more smoothly

I pulled the buffer out of my SBR and weighed it and inspected it. It appears to be a BCM H2 which weighs in at 4.6 oz per their specs and 4.585 oz on my scale.

I am 95% sure it's a BCM.

One plain vanilla buffer coming up.

[alamo5000]

I emailed tech support at Griffin and they said their 4.9oz buffer was extensively tested but only with a standard spring. So with a 4.6 oz buffer and an XP spring that should take me about to the same place as their 'special' buffer.

Should be GTG because that's what I got already and it's proven.

Like I was saying above though, four choices of H2 buffers all gave me different buffer weights all on one major gun retailer's site. Pain in the ass. Both of us

Since your playing around, have you looked at the Armaspec SRS setup?

Hear a lot of good things about them at less then half a JP setup

I've never heard of them. I finally figured out what kind of buffer I have already (it was a pay it forward buffer to help me trouble shoot a problem).

In the future I might experiment, or if someone else has tried it and it's remarkably better I would try them out for sure.

[mustangfreek]

Heard nothing but good things from people that use them.

I’ve been eyeballing them forever.
