The Fortis Billet Upper is a precision piece, machined from Billet 7075 T6 aluminum.  Like our other products, we designed this upper with function as well as form in mind.  We shaved off the ounces where we could without sacrificing rigidity or strength.  The end result is increased function and performance with the design aesthetics that we're known for.  See for yourself and you'll see and feel the difference with our products.


  • One Piece Billet Design
  • Aircraft Grade 7075 T6 aluminum
  • Military Specification Type III Hard Coat Anodized
  • Engraved logos on both sides as well as the top
  • 1913 picatinny rail flat top
  • Includes installed upper parts kit
  • Light weight at 8.6oz (including UPK)
  • Made in the USA!

Excellent, will buy again!Review by Justin
This worked really well with the Rainier mod 3 billet lower I bought, I may try the Rainier upper if it's availible, but the fit and finish on the Fortis is right up there with uppers that cost a lot more. (Posted on 7/28/2016)
loose Review by Mark
ya 3 stars but still functional ill keep it for one of my own builds. fitts loose and the flat surface about two inch across you can see day-light. this nothing new to me and im sure the fortis receiver will work well.
I know rainier has a good policy for returns but ill keep it. (Posted on 3/25/2015)
