Faxon Firearms has built a reputation for making high quality, lightweight AR-15 components. With their most recent project, they quite possibly have outdone themselves by producing a factory AR-15 for consumers that weighs in under 5 Lbs. The FX5500 Ultralight AR-15 tips the scales at precisely 4.99 Lbs to secure that coveted title of “Crazy Light AR-15.”

This rifle is not “partially complete” or “some assembly required” either. It is an actual, fully-built rifle top to bottom. Faxon Firearms did not skimp on the quality of the components in order to produce this firearm either. The complete and thorough build list for the FX5500 Ultralight can be read below.

Upper Receiver:

  • 5.56 Nato 14.5″ Pencil Barrel w/ Pinned & Welded 3-Port Brake (Meets NFA 16″ Minimum Barrel Length Requirement)
  • Faxon Enhanced Forged Upper Receiver

Now here comes the make or break for most consumers. The MSRP is currently benchmarked at $2,099 for those who are interested. The specifications for this rifle are impressive enough so it remains the shooter’s decision if they want to dive in or not.

A final convincing statement provided by Faxon Firearms for the Press Release of this new rifle is provided here:
