I had this cad file of a prototype front  sight base made up .
I was thinking about making some .
They will be CNC cut from billet not cast.
What does the hive think?
Sorry for the bad pic

Dang right when I snag a cast one in the EE. I would still be in for one though, looks good!

Braceman is welcome to borrow a genuine unfinished 1950's casting that was rescued from an Armalite dumpster.

The casting was loaned to Nodak Spud a couple of years ago for measurement and evaluation.

I could possibly have a exact 3d scan made of it at work and bribe a designer to surface it.

Edit: we have this.

just out of curiosity is there more to this story?

Cast or Machined, I don't see them Not selling.  People will always want one.  Can't go wrong making a batch.

Most of the items recovered were for Hollywood AR10's.  However, there were a bunch of first generation buffers.  According to Reed Knight many of the first 25 AR15's had their buffers and other internals upgraded later on.  Some of the buffers in my pile are used and would have been installed in the first prototypes made by Armalite.

The items were bought from an estate - I did not personally dive in the dumpster.  However, before I was in the picture various other guys had bought items.  The seller claimed that he sold a genuine upper with the trigger charging handle.  



The smaller AR15 buffer is shown next to a pair of early AR10 buffers.

I'm in for a couple.

I had a customer send me a sight base from the last batch to be finished machined , then i realized i never got one for myself.
I paid one of the engineers at my day job a bottle Jack to draw it up on Solid Works .

I'd be in for one or more... I want to build some kind of "prototype - carbine - sbr".

Now maybe if enough of us got together we could convince
John to machine some 601 front sight bases

I always wanted to know why FSB's are not generally made from aluminum?  I realize there is some advantage to a little weight ..  but is there any reason why aluminum would not otherwise perform?

Erosion from the gases and pressures combined with the cheap costs of forging and casting with steel in the 50's and 60's probably made it the go to material.
