Key Features
- 10.5-inch barrel — WHY IT MATTERS: Keeps the overall length short for easy handling in tight spaces, while still giving 300 Blackout enough barrel to burn powder efficiently for both supersonic and subsonic loads.
- Chambered in 300 Blackout — WHY IT MATTERS: Lets you switch between subsonic (for suppressed shooting) and supersonic (for hunting or self-defense) ammo without changing anything but the cartridge.
- Lightweight design — WHY IT MATTERS: At just over 5 pounds, it won’t weigh you down on a hike or during a long range session, making it a great option for younger shooters or smaller-framed adults.
- Direct impingement gas system — WHY IT MATTERS: Keeps the platform simple, reliable, and easy to clean — exactly what a family shooter needs for training and practice.
- Compatible with standard AR-15 parts — WHY IT MATTERS: You can upgrade the trigger, grip, or stock (with a pistol brace) using off-the-shelf components, so this pistol grows with your skills.
Who It’s For
This AR pistol is ideal for the family shooter who wants a compact, easy-to-handle firearm for home defense, plinking, or introducing new shooters to the AR platform. It’s also a great choice for hunters who need a lightweight, maneuverable rifle for brush hunting with 300 Blackout. If you are a beginner looking for a reliable first AR pistol that doesn’t break the bank, this is a strong contender.
Pros and Cons
- Pros: Lightweight, reliable gas system, short barrel for easy handling, 300 Blackout versatility, compatible with common AR parts.
- Cons: The 10.5-inch barrel does produce a louder report and more muzzle flash than longer barrels — ear protection is a must, especially with supersonic ammo.

FAQ
Is this pistol legal to own in all 50 states?
Yes, this is a pistol with a 10.5-inch barrel and no stock, so it is legal in most states. Always check your local laws regarding pistol braces and NFA items — but as sold, it is a standard AR pistol.
Can I use this with a suppressor?
Yes, the 10.5-inch barrel works well with both supersonic and subsonic 300 Blackout ammo. Subsonic loads are very quiet with a suppressor. Just make sure your suppressor is rated for 300 Blackout.
What magazines does it use?
Standard AR-15 magazines work fine for 300 Blackout. You can use your existing 5.56 mags — just load them with 300 BLK ammo.
Is this a good first AR pistol for a new shooter?
Yes, it is. The 300 Blackout recoil is mild, the pistol is lightweight, and Faxon’s reputation for reliability means less frustration for a beginner. Just make sure you have good ear protection because the 10.5-inch barrel is loud.
Does it come with a pistol brace?
No, it ships as a bare pistol with no brace. You can add an aftermarket pistol brace or run it as-is with the buffer tube.
