Keep that aluminum-bodied 2.500" buffer - it only fits 2 weights, and they're both tungsten.  That's the only way it makes it to 3.8oz in the first place.  You won't gain anything replacing one of the buffer's tungsten weights with one of the ones you have on hand. 

You can buy a cheap, stainless-bodied buffer from DSG Arms, and it comes with steel weights, weighs 3.8oz.  Swap the tungsten weights into it, and it give you 5.15oz.  That's running in my .260 Rem right now, and still works.  It's at the bottom end of what I'm comfortable with, but it runs. 

Here's the DSG buffer you'd need, and it's $22:

Read it all and watched the video's too.  Good info. Thanks

Since I still need buffer tubes, I just bought 2 of these kits with 5.6 ounce buffers.

Lower completed.  Just waiting on  buffer tube.

It's finished except for tightening the castle nut. Glad to say Noreen DPMS lower fits fine.  I'm waiting on a mail order magazine vise block. Put in a KAW 5.7 oz buffer. I also got an Aero M5 stripped lower which also fits fine with the BCA upper.

Thanks to everyone for their help and patience.

Looking forward to shooting this thing, man - can't lie.  Let us know how it runs.

Absolutely.. It's the least I can do for all your help.  BTW:  Too bad the attached picture isn't available in .308  ZOOM IN TO GET THE MESSSAGE.  I ordered one anyway.
