Mancraft Hybrid Carbon-CNC M4/M16/AR15 outer barrel
Lighten and stiffen the front end of your M4/AR15/M16 replica! The Mancraft Hybrid Carbon-CNC is an ultra-light outer barrel designed for TM-standard M4/M16/AR15 platforms, combining a high-grade seamless carbon fiber tube with precisely CNC-machined aluminum components.
This design was created for dynamic CQB builds, lightweight HPA / AEG setups and longer AR configurations, where every few grams saved has a real impact on balance. Each barrel features two inner barrel stabilizers, each with two O-rings, for excellent coaxial alignment of the entire assembly.
Key features:
- Ultra-lightweight construction that improves agility and reduces fatigue during long games.
- The simplest way to reduce front-end weight - a carbon barrel is on average 2–3 times lighter than a stock barrel made from machined aluminum castings.
- Combine this outer barrel with our CNC handguards and you will get a super light and stiff construction with a unique look.
- For example, the 16.5" version weighs only 98 grams!
- Premium seamless carbon fiber tubes with a matte-satin outer surface.
- Larger 20 mm outer diameter so the barrel keeps proper proportions and does not visually stand out compared to a typical stock metal barrel.
- Thick carbon tube walls provide high stiffness - ready to be used with tracers, mock suppressors or the Mancraft Mjolnir Amplifier.
- A solid barrel base with stainless steel locating pins ensures perfect and long-lasting positioning inside the upper receiver.
- Two inner barrel stabilizers, each with two O-rings - for excellent coaxial alignment of the entire structure.
- CNC precision of the aluminum components guarantees an excellent fit and a stable hop-up chamber position.
- One of the widest length selections on the market in 0.5" increments from 10" to 19.5". We also offer shorter barrels – Mancraft MSB in the 5–10" range, as well as the 20" Mancraft MHB barrel for DMR/sniper setups.
- Anodized M14x1 CCW threaded tips in four colors: black, brown, olive and silver.

FAQ:
Will the barrel fit every M4 replica?
It is designed around the TM standard and works with most popular Airsoft M4/M16/AR15 receivers. For non-standard designs we recommend checking compatibility.
Can I use a tracer or suppressor?
Yes. The thick carbon walls provide high stiffness, so the barrel handles 14 mm CCW threaded accessories very well.
How do I choose the right length for my handguard?
The best rule of thumb is to choose a length where the threaded tip is either slightly recessed or just protruding past the handguard edge, depending on your preferred look and accessories.
Is this a firearm part?
No. This component is intended for airsoft use only.
