DIY weighted buffer / BCG

While recouping from major surgery I have been researching DIY projects to add Wt. to the OME buffer or adding Wt. to the BCG.The store bought heavy buffers weight between 9.5 and 10.0 OZ. depending on the Manufacture RRA Lar 8 and Armalite AR 10 T.
I know the easiest way will be to shell out $ 150.00 to $ 200.00.
Just wondering if anyone has any experience or knowledge of such projects
Thank you

Why do you want to add weight to the carrier or buffer? Is this to avoid using an adjustable gas block?

In my experience, 308 AR rifles can benefit from going the other way, i.e. lightening the bolt carrier to reduce reciprocating mass. My carrier is now the same weight as an M16 carrier, and with a carbine buffer and gas adjusted correctly, the rifle is less picky about shooting position and easier to shoot well.

I take it the weight fits inside the buffer ?? To bad they don't list the weight, the OD, and the demolitions so one could actually determine if they would add the desirable amount of weight
 
You will find that most of the tungsten weights weigh around an ounce and a half each. An Amazon seller list a pack of 3 for 27 bucks.

Doesn't sound like you know much about AR buffers. This will help you understand. http://thearguys.com/ar-facts/difference-ar-15-buffers/ As you see
, all buffers have a series of weights inside of them. Varying combinations of steel and tungsten weights and spacers determine the total buffer weight. You don't mention what caliber and stock configuration you are working with. The article I linked to doesn't address the AR10 buffers but there are 2 different lengths depending on the stock setup. Hope this helps.

Thank you , interesting & informative article. Both AR's are in 308 one an Armalite AR-10 T, and nib RRA LAR-8.{ Rifle length stocks} As I said in the beginning, I'm recouping and use a walker to get around my house, As soon as I can I'll get both AR's out of the safe,I'll see what they have inside inside them, and see how many Tungsten "pills" they will hold, and go from there

I added weight to mine because I couldn't get it to run reliably with a suppressor.....even with an adjustable gas block. The bolt was unlocking prematurely and my brass was getting beat to hell. Extra weight in the buffer helps the bolt stay closed a little longer so the brass can shrink back down and make extraction easier.

If the gas was tuned correctly, the bolt shouldn't be unlocking prematurely. What am I missing?

I use mine with a suppressor as well...
