16″ .223 Wylde AR-15 Barrel – Non-Threaded, 1:8 Twist
Looking for an AR-15 barrel without muzzle threads? This 16″ Mid State Firearms barrel is built around a straightforward, practical configuration: a .223 Wylde chamber, 1:8 twist, 4150 CMV steel with a nitride finish, carbine-length gas system, and a non-threaded, crowned muzzle. Great for compliant builds.
The non-threaded muzzle is a unique feature of this barrel. Instead of the conventional threaded muzzle found on most AR-15 barrels, the muzzle is finished with a clean crown and no external threads. This makes it an option for builders who specifically need or prefer a non-threaded barrel, including certain builds where applicable laws or regulations restrict threaded barrels. Always verify the requirements that apply to your specific location and configuration.

Why .223 Wylde?
The .223 Wylde chamber is designed to provide reliable compatibility with both .223 Remington and 5.56 NATO ammunition while using chamber dimensions intended to support consistent performance with a broad range of loads. It is a common choice for AR-15 barrels when versatility across .223 and 5.56 ammunition is desired.
1:8 Twist Rate
The 1:8 twist is a versatile twist rate for the AR-15 platform. It provides a practical balance for a broad range of commonly used .223/5.56 bullet weights, making it well suited to general-purpose builds.
4150 CMV Steel with Nitride Finish
The barrel is manufactured from 4150 chrome-moly-vanadium (CMV) steel and finished with a nitride treatment. Nitride hardens the surface of the steel and provides increased resistance to wear and corrosion while maintaining the underlying characteristics of the barrel steel.
.750″ Gas Block Journal with Dimple
The barrel features a .750″ gas block journal, one of the most common gas block dimensions used on AR-15 barrels. A factory dimple provides a reference point for positioning a set-screw-style gas block and helps establish consistent gas block alignment during assembly.
Non-Threaded, Crowned Muzzle
The muzzle is not threaded. Instead, it is finished with a recessed/crowned muzzle profile.
This configuration is particularly useful for builders specifically looking for an AR-15 barrel without muzzle threads. Depending on the applicable laws and regulations, a non-threaded barrel may also be required for certain compliant configurations.
Always verify federal, state, and local laws before assembling or configuring an AR-15.
Mid State Firearms
Mid State Firearms builds and assembles AR-15 components with an emphasis on proper specifications, quality control, and practical configurations. This barrel is intended for builders who want a versatile .223 Wylde barrel while specifically avoiding a threaded muzzle.
Note: Barrel specifications should be verified against the product information and photographs before purchase. Ammunition and firearm compatibility are the responsibility of the end user.
sound of freedom – This was a great set up. I loved being able to customize the set up. Only issue I had was my own fault as a newb to building these. I used a heavy barrel in a slim hand guard. It makes adding attachments tough with clearances. Hoping someday to also get an AR10 from here.
