Heavy Carbine buffers?

[Bill]

Not sure if it will really help with accuracy, but minimizing as much of the "recoil" as you can lets you stay on target for faster follow up shots.

I have always run the "heavy" buffer in all of my carbines with no problems. Most with the mid-length gas system but a few with the carbine length gas system.

I recently put together my first 14.5" with the mid-length gas system and was worried it might not cycle properly with the heavy buffer. Turns out it cycles just fine. 300 rounds and no problems yet.

I think you'll get more noticeable results with a good muzzle device than you will the buffer.

You can see in this video that my 14.5" middy is very controllable.

Thank You

what weight of the "heavy" buffer do you use. 4oz range or the 5oz range?

[Kaiser.Shooter]

buffer weights:
H- 3.5-3.8oz
H2-4.2-4.6oz
H3-5.4-5.8oz

If you would like to try a heavy buffer I can make you one with any of the weights above.
I have a tungsten powder and buffers or I can use your std buffer.

I'm afraid I don't have a good answer for you. I never actually weighed them. It's just marked with an "H".

I have a similar setup to Ray's, 14.5 pinned mid-length gas system. The Spike's ST2 I am using is 4.06 oz, smooth cycling. I have a standard flash hider nothing more on it and it felt very controllable. Ray's in the video he posted has the PWS mini flash hider/Comp, very nice, I liked it so much, my second 14.5 pinned middy uses the standard PWS.

BP's comment about refined trigger would go a long way as well, but those for the one he mentions is in the $200+ range. Control your rifle or control your wallet....................

I just use the H buffer for the most part, although I do have a Spikes ST2.
I have used a variety of muzzle devices, and the favorite so far has been the AR Stoner Competition, which is pretty much the same as the JP Comps, just cheaper, and I just picked up an Arredondo comp to try, which I also think will work well. Have tried the Troy Medieval comp and its ok.
Agree with what Bert had to say, the buffer has more to do with the cycling of the rifle, the comp, rifle weight, stock fit, and ammunition selection is what affects felt recoil.

Thanks For the Help, thats the info I was looking for.

Hey this link does not work please repost with a good link. Thank you

[Kaiser.Shooter]

it works, good vid
let me know if you want to play with a different weights to see what works better in your rifle

[ray1970]

Dang. Now I am going to need a high speed camera to check the function of my action.

If your buffer doesn't rattle when you shake it, it can lead to "bolt bounce". That's why you won't find the Spike's buffers in my rifles.

The little weights rattling around in the buffer serve a purpose. It's sort of a "dead blow hammer" effect. As the spring pushes the buffer and BCG forward, the weights inside the buffer are shoved to the back of the buffer. When the bolt gets all of the way forward and stops, those little weights fly forward inside the buffer to counteract the bolt wanting to bounce back.

You can see the bolt bounce I am talking about in the video linked to above.

The big difference between a standard carbine buffer, an "H" buffer, and the "H2" and "H3" is the materials used for the little discs rattling around inside the buffer.

A standard buffer has three steel discs inside. The "H" buffer is slightly heavier because one of the steel discs is replaced with a tungsten disc. The "H2" has two tungsten discs, and the "H3" has all of the discs inside made from tungsten.
