Is this a H buffer? > Rifles, Uppers, Lowers, Barrels, and more

Posted: 12/4/2006 11:23:45 AM EDT

I'm having cycling problems with my M16 and it seems to be because I need a H buffer. I found this DPMS buffer that seems to be the same while it doesn't say it's a H buffer (Colt designation?). Will this one work the same as a H buffer? Thanks.

from Brownells: SPECS:Steel body. 3¼" (8.3cm) long. 5.4 oz. (155 g) wt

that's close to a H3 buffer weight

An H buffer weights 3.8 oz.

So what is the purpose of this buffer if it's so much heavier than the H buffer?

That one is close to the weight of a H3 buffer (5.6oz)

here's a little reading

But how do you know if you need a H3 buffer vs. 9mm buffer vs a plain H buffer? Can I ever go wrong with a H3 buffer?

Rule #1: If it ain't broke...

Unless your weapon is select fire you really wouldn't know if you had a problem.

Well, like I said in my original post, I have a M16. I was having cycling problems in full auto until I put someone else's H buffer in. So, can someone please tell me when to use a H buffer vs. 9mm buffer vs. a H3 buffer?

There's no "when". You just use the one that works. Probably the only general rule that applies is that shorter barrels are more likely to need heavier buffers.

So do you forsee any problems if I go with the H3 buffer in 10.5 inch to 20 inch barrels? In other words, can the buffer ever be too heavy and cause malfunctions? I will most likely use it with short barrels.

Too heavy can cause problems with lighter loaded ammo, especially as gas system length increases.

Ummm... it's pretty easy.

Get your rifle, use your standard ammunition... put in a H buffer? Yes? Try a h2 then a H3. When your rifle fails to function, go back to the lighter buffer that worked.

Going to a heavier buffer does reduce felt recoil and slows the cyclic rate of the firearm, or it could cause any particular rifle to malfunction. The only way you'll know is by trying them.

What type of malfunctions are you having? Bolt bounce or failure to extract/eject and chamber a new round. From my understanding if you are having bolt bounce/light primer strikes or failure to extract due to chamber pressures being to high you would need to go to the next heavier buffer and so on. If you try the single round gas system test and the bolt does not lock back on an empty magazine a lighter buffer may help.

It's definitely a buffer issue. In full auto, I can get no more than 2-3 rounds off before it jams. Once a H buffer was put in, it ran flawless.

Then get a H buffer
