Does anyone have a good tip to duplicate Colt factory castle nut staking?  - Outside of grinding down a punch, using a screw driver or buying the unobtainium H&K punch/stake tool?

I got robbed of my factory staking - long story for another time.

tagged; best idea I've seen previously is to grind down a punch, but haven't seen any specific dimensions

The colt factory staking is done in some type of press setup

I found a watch staking punch on eBay that looks like it might get close but it is so hard to tell from the photos.

You could just send it to John Thomas at Retro Arms Works. He has the exact setup and jig to keep everything straight and stake it perfectly on any endplate. I For small jobs, he will often do it and ship it back on the same day he receives it.

Thanks for the tip.  I will check him out.  I would prefer to avoid sending it off since it is a SBR.  I know it can be shipped but I would rather take care of it in house if I could find a correct or similar tool.  

FCD used to make a stake-punch that was rectangle/square but apparently they changed the design.

Colt did me so dirty I am beside myself.  I may actually break my own rule and post a Youtube video about it.  I will never purchase another Colt product again.

I will send you a PM.  I don't want to start a pissing match in their community forum.
