found this black buffer, looks to be plastic and it weighs in at 1.6-1.7 oz
where might this have been used ?? and why ?? . 
|
| I was curious about this so I looked it up. I read a post on a different forum where a guy said he was running a 2 oz buffer on a 7.62x39 AR-15. He said it was a piston upper. I am not sure about this but maybe piston uppers use a lighter buffer? I really have no idea but it is just a guess. |

Not sure about 7.62X39 AR piston buffers, but my LWRC, AR15, 5.56, 16" barrel, M6A2-S came shipped with an H2 buffer as did an identical M6A2 with carbine gas length...the "S" model designating mid-length gas. I draw from it that a piston AR probably doesn't need a lighter buffer and may indeed need a heavier buffer. Not sure if this is a general thing across the board or just particular to my LWRC's...but I doubt that there's anything that weird about the LWRC among piston rifles...is there? |
| I know the 3 gun guys use them. The JP low mas buffer is based on this, it's a rifle buffer that is 3oz I believe. The idea is that there is less recoil and the bolt gets back into place faster for quick shots. It's not recommended unless its run with a adjustable gas block at the very least and normally with a low mass BCG. Gamer guns are designed to be tuned to one load. |

It's probably been taken apart, and the weight modified to increase the cyclic rate of the weapon it was in.
As already mentioned, though, there are a few companies that have used light weight buffers just for this purpose. But also in conjunction with adjustable gas systems for a complete tune of the rifle. |

My MR556 buffer is definitely heavier than the standard buffer. |
