AR Buffer Spring Database

[BigNate]

OK - I've been digging on the interwebs and have come up dry.   I may decide to make a project out of this - if it doesn't yet exist.    Is anyone aware of a forum / website / etc. that contains actual data about buffer springs?  I'm thinking things like:

• Length
• Number of coils
• Wire diameter
• Wire type
• Spring rate in lb/in
• Coil bind height

Maybe I'm just a math / details nerd - but it would seem much easier to adjust if there were more specific data available.   E.G. If my Sprinco red spring has a spring rate of 2.7 lbs / inch - and I'm looking for a nominally softer spring - knowing which, of the same length / bind height had a spring rate of 2.5 lb/in would be a handy bit of information.  

Am I nuts?

Not buffer springs specifically, but I found this:

Thanks much... good info there...  I think I'm probably going to build a tester and start building my own dataset... we'll see... 🙂

You're welcome. Share what you come up with, it'll be interesting for aure.

We already have info here, on alot of that, through the years.  The best source of n0-bullshiit information in Sprinco.  They list it all.

This page of theirs is worth it's weight in Gold Bullion...

If you want to REALLY know wire diameter, coil count, relaxed length of the spring, and all that, there is no better resource that Clint @ HeavyBuffers.com.

He lists ALL the details of what you need in a spring, to make a functional gun - that's gassed right.  If it ain't gassed right, and you think his spring info and buffer info didn't help you - he'll fix your recoil system.  If what he says doesn't fix it - then you have a gas system problem.  Period.

Between the two of those vendors/resources - that's all the information that you'll ever need, if you're looking to solve recoil system problems.

If you have gas system problems, that's another story. 

Get the correct recoil system in your gun, and I'll solve the gas system problems.  It's a short list, after the recoil system is straight.  Minus weird shiit, it comes down to gas tube length and gas port diameter, per caliber, barrel length, and dwell time.

I had been digging around on the Sprinco site and had read the details on their springs - but I'm missing details...  I see "White" is standard, "Yellow" is "approximately 20% lighter than the White spring..." Blue is "15% greater than white... " etc. 

I'm a math nerd - and I was trying to do some math based analysis of how much energy I was absorbing so that I could do some regression modeling and try to better predict what I need in a given situation.   This is mostly an academic exercise for me... I'm working as it sits - but would love to be able to compare spring rates etc across product lines.  Am I missing "number" on their site somehow? 

 

The heavybuffers site looks awesome!  Thanks.

No, they don't list the relaxed length, wire diameters, coil counts - just the good descriptions of the intentions of the springs for use.  The numbers are in the HeavyBuffers info.
