Heavy Buffers... technical questions

[alamo5000]

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.

99% suppressed all the time on this one with the option for unsuppressed, but very unlikely.

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

It's almost like you know me!

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


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

It's ok. We all gotta laugh even if it's at ourselves. You did touch on an important part...new whizbang parts that are supposed to be special... do they really work? This does make me wonder sometimes. Just put in a search for H2 buffer and you get a dozen varieties all in different weights.

And to Aragon's point...if you have an already functioning system, don't screw with it. You're good. Don't over-think it.

Understood.

My point is this... my current SBR won't be touched. It's staying like it is and I won't have to swap uppers anymore. Having an upper with no lower makes me feel kind of naked. It has to grow into a full rifle hence this whole build and putting together a new lower. It would be pretty easy to find a standard weight H2 buffer (or so I thought) and get the same spring I have and call it good.

That said as I hunted around for buffers in the H2 range they have a shit ton that are not at all 'standard' weight or whatever.

My question originally is kind of simple---but the answers might not be I guess. Basically put "if my buffer is too heavy what's gonna happen?" [read: if it's going to be a pain in the ass I don't want to mess with all that bullshit]

I know the lower will need a heavier buffer. This is a known quantity. But I go to order a plain vanilla heavier H2 buffer and a search on single site turns up no plain vanilla, just a 4oz, 4.3oz, 4.5oz, and 4.9oz and said marketing material leads to this thread.

If I under do it I know what will happen. Bolt over base, carrier speed too fast, constant stoppages, mangled brass, etc. If I over do it though and put something too heavy what are those symptoms? No LRBHO, maybe short stroking? Anything? Can basically an extra half oz cause things to be too slow? Is that even a thing?
