Delphi Tactical "Man At ARms" Rifle

Delphi Tactical



  The Delphi Tactical DELPHI-15 "MAN AT ARMS" Rifle... A man-at-arms was a soldier from the High Medieval to Renaissance periods who was typically well-versed in the use of arms. A man-at-arms could be a knight or nobleman, a member of a knight or nobleman's retinue, a mercenary in a company under a mercenary captain, or a modern day American Patriot.

  The term man-at-arms thus primarily denoted a military function, rather than a social rank. This everyday battle rifle is the perfect balance between high quality components and affordability with uncompromising accuracy. Backed by our rock solid sub-moa guarantee and transferable lifetime warranty.
