I have a standard ar10 buffer, I belive they weigh 5.? oz, I though about getting a scale and cutting the back shank on a busted up carbide endmil with a cutoff wheel on a surface grinder and then surface grinding the small section until the total weight is up around 10 oz
any one think this would work and cycle and all that ? UPDATE: i got a pound of carbide powder to put into my buffer and when i did so it weighed the same as it did before the carbide powder, so now what ? any one know any tips or tricks ? |

You're talking about adding your "busted up carbide end mill" to your existing buffer? (Your description of what you were planning is kind of vague...)
Why not just get a heavier buffer? It's important to note that buffers aren't just a specific weight. They have moving weights inside them to basically slow them down to one extent or another. Just adding weight to double the mass of your current buffer may or may not do something you want. The real issue is why you want such a heavy buffer in the first place. What are you trying to achieve? |

What exactly are you trying to do? With the end mill? Use it as a weight? You'll need to get rid of the sharp edges or it will eat the aluminum buffer casing from the inside. ok let me say this all over again, I want to find an end mill at the shop that some one fucked up, a junk one, I want to put it on the surface grinder with a carbide cut off wheele I am going to cut the fluted section off cause its busted and junk, then with the perfectly round shank ( part you hold onto ) I want to cut off some small sections like maybe 1/4 wide sections, yes I will brake that tiny edge and smooth it out. basically making exact copies of the weights inside my original buffer just instead of the weights being say 1 carbide and 3 steel id like their to be enough carbide weights to make the buffer heavier, 10 oz is what I am going for, because I want to buy a slash 10 oz buffer and spring kit to reduce the recoil some but until I get that coin I though id just try this and see how it feels, maybe fire a mag threw it if it works, then put the factory buffers back in and in a month or so buy the slash buffer |

OK, that's a lot more understandable. I think it's also a lot of work. How bad is the recoil now? Quoted:

I bought a Slash heavy buffer and it absolutely INCREASED the recoil of my AR10. It did nothing of what it was cracked up to be.
Increasing reciprocating mass slows the unlocking process, but it is NOT necessarily a reduction in recoil. If your barrel is significantly over-gassed (as all DI designs are to a degree) it can increase felt recoil when the added mass slams into the back of the receiver extension. The best formula for reducing recoil is to REDUCE reciprocating mass at the same time installing an adjustable gas block to control gas impulse. |

I have a slr-da7 adjustable gas block, to set it up I shut it all the way off, then gave it a full turn out shot the rifle it didn't cycle so I gave it a half turn, it short stroked I gave it a 1/4 turn, it cycled so I gave it one more 1/4 just for the reliability factor and left it their |

Did you replace the spring as suggested? Quoted:

I bought a Slash heavy buffer and it absolutely INCREASED the recoil of my AR10. Did you replace the spring as suggested? Bought one at the same time, yes. I assume my barrel is overgassed, and adding mass to the buffer, while slowing unlocking, still builds significant velocity to slam the mass rearward and increased felt recoil. The more I learned about this, the more I realize that controlling the gas impulse is a far better solution than just adding mass to the buffer, for recoil management. Slowing cyclic rate and controlling bolt bounce, is where I'd consider more mass on the buffer in the future. |

Quoted:
Your assessment makes perfect sense. The 1st buffer I bought from Slash, I went cheap & didn't get the XP spring. Had a similar increase in felt recoil. What barrel are you running? Adjustable gas block an option? Lothar Walther stainless. Yep I can install an adjustable gas block for the .875 diameter. |

I am on another build trip. I have several Spikes Tactical T2 buffers that use tungsten powder instead of steel and tungsten discs.
Not sue if they are the cause, but I NEVER heard the AR twang until I used a lower without the T2 buffer. Getting an AR10, going to make a heavy rifle buffer. Purchased a bottle dog ear tipping weight tungsten. It was the best price for pure tungsten, $14 for 3 ounces of powdered tungsten. Going to take the AR10 buffer apart and put the powdered tungsten in. Hoping for another two to three ounces. Heavy AR10 buffers are VERY EXPENSIVE ($125). Standard rifle weight is 5.4 ounces, Heavy Buffers makes a 303 stainless 10 ounce buffer. Of course this will also work for our AR15 buffers. |

Call Slash and order one of his heavy buffers |
| I put slashes CAR-10 buffer into my Armalite AR-10A (CBFX). I got the heavy carbine buffer springs, but not a tube. The springs were shorter than the Armalite spring, so I left the Armalite spring in and just replaced the buffer. It shot all right. I am about to replace the buffer tube with BCM standard mil-spec and try Slash's springs, I'll let you know how it goes. |
