FAXON ION-X HYPERLITE 10.5" 5.56 AR15 PISTOL
Faxon ION-X Hyperlite 10.5" 5.56 AR15 Pistol
The ION-X Hyperlite is built to close the “lightweight vs. rugged” decision gap: a complete AR15 pistol that comes in at 4.93 lbs, while still delivering duty-grade materials, suppressor-ready capability, and Faxon’s in-house manufacturing credibility from Greater Cincinnati, Ohio.
4.93 lbs 10.5" 5.56 NATO Duty Series 4150 CMV Barrel Pencil Profile Carbon Fiber M-LOK Handguard Patented Adjustable Gas Block Suppressor-Ready Ecosystem Made in the USA (Ohio)
What it is
The Faxon ION-X Hyperlite 10.5" 5.56 AR15 Pistol is a factory-built lightweight platform engineered for fast handling, practical recoil control, and real-world reliability—without forcing you to “piece together” an ultra-light build and hope everything plays nicely. Faxon designed the ION family to deliver complete-rifle confidence backed by a manufacturer with deep machining heritage (advanced manufacturing roots dating to 1978) and a modern firearms brand founded in 2012—built and assembled in Greater Cincinnati, Ohio.
At the heart of the system is a Faxon Duty Series Pencil Profile 10.5" 5.56 barrel (4150 CMV, salt-bath nitrided) chosen for strength-to-weight efficiency and long service life. The streamline carbon fiber M-LOK handguard further reduces forward weight to keep the pistol lively and quick, while the Faxon patented adjustable gas block helps you tune function for ammo and suppressor setups.
This is a smart fit for shooters who want a compact AR for training, property use, and travel-ready convenience, and for buyers building a suppressor ecosystem who want an adjustable platform from day one. It’s also ideal for anyone who values weight savings that you can feel without stepping down into “consumer-grade” components.
Who it’s for / not for
- Best for: Lightweight AR pistol builds, training, compact setups, suppressor-tuned configurations.
- Great match: Buyers who want a complete, engineered system—barrel, gas, handguard, and controls selected to work together.
- Not ideal for: Buyers who need a rifle-length platform or a different barrel length for a specific role (e.g., dedicated long-range).
