About us


We were born out of the need to keep people safe.  Many people own firearms they have never used, or maybe a friend let them fire a couple of rounds in a one-dimensional world.  Well no more, welcome to the real world.  We will provide you with an experience unlike many of you have seen.  We live in a 3-dimensional world, so you may as well train that way.  Besides, it will keep everyone around you safe.



Pete is the founder of Cross Valley Training, with a passion to help those in need.




Welcome to our parent company where everything began.  The owners of Brothers N Arms started out of a garage selling and fixing firearms over a decade ago.  As time went on they moved to commercial buildings and expanded their products to include their own line of firearms, prototype firearms, and eventually private label firearms.  As they grew they realized they need to restructure and rebrand, and born out of that was Archimedes Machining.
