AR 15 in .41 Magnum.

[Silentwind]

I am considering building one in .41 Magnum. Where can I obtain a 16" barrel? Also need information on a BCG. I checked my 458 Socom BCG and it is to small.

Chances are you will not find a bolt that will fit and function reliably. Too much material will have to be milled out to fit the head of the case

The .458socom bolt is already thin enough, the .41mag rim is another .020" larger than the .458 socom rim. Then there is getting a magazine to work right with rimmed .41mag brass. Better off just going with a 10mm or a .44automag if you want something more exotic. You can use a .458socom bolt with the .44automag.
