What is the difference between standard, H1, H2, H3, buffer tubes? Which one should I use on my core lower? They are the BCM website

I am also interested in this........

i never even heard of H1 H2 or H3 buffer tubes  just mil vs commercial (and of course material type)


are you sure you didnt mean buffers?

if your talkinf about buffers its all about the weight. standard has 3 steel weights  H has 1 tungsten and 2 steel h2 has 2 tungsten and 1 steel and h3 has  3 tungsten. H= heavy

These aren't the tubes. It's the buffer itself. The heaver the buffer the slower the slower the action an the less felt recoil. Some else will chime in with more.

this and if your doing a full auto the standard buffer isnt heavy enough. you need at least a H buffer.

Ohh. So basically I shouldn't care?

basically they all work but in diff ways. if your building a regular semi carbine then anyone of those will function. when you want to start fine tuning and messing with it, then you need to know more about it.

for example if you buy a RDIAS and want it to run you need a heavier buffer. if you want to change the way it feels or if you decide to run suppressed you may run into cycling issues and diff buffers can help solves these types of problems.

for for a basic build it is not necessary, but as you play with it and want to change it up then maybe.

the H3 can be very picky though. Because it comes with a longer buffer spring and is also aslightly longer buffer. So in some tubes you wont be able to pull the charging handle back all the way. Happened in my stock DDM4

thanks for giving more info on this I appreciate it

Hello all, still learning here.  

So I am building a lower for a 20" barrel.  Would you recommend buying the "standard" weight?  

I am leaning toward the Magpul STR stock with the Bravo Company tube and standard weight.  Does this sound right.

You need to care, because a buffer that is too heavy will induce failures, depending on the rifle and ammunition.  Shorter gas systems, by and large, benefit from a heavier buffer.

Unless you're using some sort of non-standard buffer, there are no dimensional differences between H/H2/H3 buffers, and they all use the same spring.

Yep, I'd use an H buffer.  H2 if you want to mess around with reducing some of the recoil impulse.
