Fusing Faxon's innovation and engineering with Lancer Systems' carbon fiber know-how, the STREAMLINE Carbon Fiber Handguard maximizes carbon fiber's unique rugged characteristics with practical application. The rail features 8 complete M-LOK facets for mounting accessories and uses standard AR-15 barrel nuts for mounting to the rifle, driving weight down, while maintaining decades-proven mounting systems.

Carbon fiber is 10x stronger than aluminum and 40% lighter. We created a carbon fiber handguard that is competition and duty ready, weighing in at only 7.99 ounces, with a steel barrel nut!

Already proven on champion competition rifles, the STREAMLINE Carbon Fiber Handguard is rugged and ready for anything a shooter can throw at it.

Features:

  • Extreme lightweight without sacrificing strength, rigidity, or practicality.
  • M-LOK attachment across 8 facets.
  • Dramatically increases maneuverability of the weapon over metal rails. 
  • Low heat transfer for handling extreme duty cycles. 
  • Fits common suppressors under-rail
  • Attaches with standard armorer's wrenches and tools.
  • Co-witness iron sights and optics/lasers*

*Requires optional low-profile M-LOK rail adapters.

    FAXON STREAMLINE CARBON FIBER M-LOK 13"

    Posted by Phil on Apr 13th 2026

    These are some of the best light weight carbon handguards. I have used a number of these in all lengths on my builds. They are great to grip, super strong, and hold up very well in any environment. Never had one come loose. Highly recommend!

    Best handguard I've ever purchased! Really set off my new build. Shaved off serious weight and really balanced my rifle. I could not more highly recommend!

    Light weight

    I recently bought this handguard because I was building a lightweight AR. It tucks my suppressor well and light is an understatement.

    Very Nice

    Posted by Justin Guarino on Sep 19th 2024

    Came in at 7 oz. My Del-Ton that I’ve slowly been replacing part by part; its hand guard came in at 11oz, so lot quite a bit there. Feels nice. To mount a front iron sight, you can get the 2 inch rail, and mount it where the slot is. Feels nice. If you’re looking into the rifle speed adjustable gas system, this will clear it.

    Great Product

    Lightweight, strong and well made. The 13" is probably best on a 14.5 barrel.

    Fantastic Handguard

    Posted by Kyle Arbogast on Jan 10th 2023

    I purchased this with the intention of doing a build with a suppressor inside of the handguard, and wanted to keep the weight down. This handguard worked perfectly for that. The suppressor fits nicely inside of the handguard, heat transfer is almost non-existant (did a 100rd mag dump to test this) with the carbon fiber, and the weight reduction of the handguard kept my weight down substantially with the suppressor out on the end.

    Amazing handguard

    Posted by Tim on Jun 2nd 2022

    Very impressed with the manufacturing. The resin on the carbon fiber was properly done. The milling on the mlok slots were properly deburred; I couldn't find a single loose fray of carbon fiber. Very lightweight, yet at the same time has heft and sturdiness to it. I had a chance to compare this to the JAG carbon fiber handguard, and this one is definitely higher quality. Highly recommend as the best per cost carbon fiber handguard w/ mlok on the market today.

    13” carbon fiber rail

    Posted by Justin Duquaine on Feb 17th 2022

    Best carbon fiber rail I have used. I have used 3 other brands and Faxon is the first that made me a repeat customer. Great design and quality.

    Quality

    Posted by Nicholas Hermosillo on Dec 24th 2021

    Super clean lines and design. Genuine carbon fiber that feels incredible in the hand. Smooth octagonal handguard that feels strong, almost alien. Wish there was a qd mount option.
