Once, when experimenting with alternatives to the CCWS, I took a standard rifle buffer and removed the sintered iron slugs, replacing them with lead shot. It increased the weight significantly, but I forget how much that was. What I observed was that by adding the weight back in the buffer as opposed to in the BC, the nylon plug on the end of the buffer got battered more, I assume from the additional momentum. Went back to the CCWS.
FWIW and this has been championed by other members, the CCWS helped with the carbine length gas system, but the best solution may be an adjustable gas block if you're trying to overcome over-gassing. Then again, slowing down the BC by limiting the rearward driving gas impingement force doesn't offer much benefit on the forward stroke. From a curiosity standpoint, if I were going to drop a c-note on anything, I might add a little to it and try one of those JPS Silent, Captured Spring units. Not that the spring noise bugs me, but because the design looks well thought out and well executed. They also sell a heavy version. I believe in either the regular or heavy version, they are designed for shorter receiver extension tubes that accommodate telescopic stocks, so you would need their nylon spacer in a rifle length tube. Folks who use them swear by them. One of them is on my bucket list.
