All my advice on buying a gun is here.

Please DO NOT write to ask where you can buy a part or a gun.

I've spent hours upon hours creating this site, putting everything I know on it.  I spend hundreds of dollars per year hosting my sites which generate no income whatsoever --  all just because I'm a nice guy.  :)  There is noting I've held back -- why would I?  So please don't write and ask me.
