Well if you got the Atrius, Hoffman, ARC-Fire or Partisan there's a solution.

KAK offers a DBC (Deadblow Carrier). It's a carrier with a reciprocating weight in it.

You can use your standard buffer in your gun. It works well and I am running suppressed on a 10" barrel.

However, if you have a lefty bolt, you are pretty much out of luck as they are usually out of stock.

KAK offers the weight and roll pin naked as an option and you drill your own bolt yourself. You can do this on your regular bolt, too.

It comes with a 3D print file to use as a jig to drill it with a 1/4" drill bit.

I have a coworker that has a LH bolt carrier and he couldn't get a buffer or DBC.

S0 I used my own DBC as the jig to drill his.

It worked so well, I made me a spare.
