Which buffer for a 10.5"?

[STS]

I'm currently putting together my first SBR and was wondering which buffer I should go with. I'll either be using a 10.5" Noveske with KX3 or a 10.5" LMT with KX3.

I'm running a H2 buffer in my LMT 10.5" along with a Noveske KX3. Runs perfect.

Thanks Marc. I've actually had several guys at the range mention the H buffer - problem is none of them actually shoot or own a SBR!

I run H buffers in all my 16" & 14.5" carbines but anything under 14.5" should have at least a H2. Some might even run H3s or a 9mm buffer but I'm happy with an H2 and a Noveske Krink ;)

I have ran both a standard and 9mm in my LMT 10.5, 100% hard to tell any difference.

I run a H buffer with a LMT 10.5 and a Colt 11.5.

Both work perfect in semi and full auto. I've also used the 2 piece Colt buffer to slow things down.

Will a 9mm buffer work as good as a H2 or better?

Will a 9mm buffer work as good as a H2 or better?

A 9mm buffer is 5.6oz and the H2 is 4.6oz, better is hard to quantify. What works 100% for you, may not for me. There's many other factors to consider which would be better.

Try an H2 first if you use a sound suppressor. If it does not lock open on an empty mag, then switch to an H.

Try it with and without your sound suppressor and with the types of ammo you use and try to find one that works for all of them.

If you don't have a sound suppressor you probably want an H but it still depends on if you use wuss-ammo or NATO ammo and what your spring and gas port is like.

I tried running a H2 in my LMT 10.5 but it would not shoot 223 loads. It would run like a champ on mil-spec ammo. I shoot both types of ammo so I go back and forth between the Carbine buffer and the H2. I plan on trying a H buffer and see if it will shoot the 223 ammo.

[rsilvers]

For me, .223 ammo does not exist. I guess if the world fell apart and it was all I could get, I would have to pop in an H buffer, hold my nose, and shoot it.

The worst imaginable use of .223 ammo, if you were forced to use it, would be in a 10 inch barrel.

I have a 10.5" LMT with KX3, and I run a Colt 9mm buffer with an ISMI spring.

I was running a 9mm buffer in mine, but the roll pin in the buffer came out a little bit, and bound up the action. Not having a roll pin with me at the moment I went with a H buffer and standard Colt carbine length action spring, that I had in my spare parts pelican. Ive put between 500-1000 rounds thru the gun in the last week and a half with no problems.

Weapon is a Colt M4 lower with a LMT CQBR upper. Sometimes I run a M496D on it, other times not.
