Paul, your new complete lowers come with a "Staked Lock Nut ".

How do you do the staking?  Can you sell a jig to do this?

Castle nuts are typically staked with a center punch.  It's easier than eating pancakes.

Yes, we use a punch.


Thanks!

Get one of those "Starett" punches from Brownells works like a charm..

So easy an Ivy Leaguer could do it.
