Description
This is a limited run cold hammer forged 5.56 barrel built from CrMoV steel with a chrome-lined bore and manganese phosphate finish. It ships with a pinned low-profile gas block already installed, so you're ready to drop it into your upper right away. The Hanson profile design is what makes this barrel stand out from the standard government options you'll find everywhere else.
Hanson Profile Design for Lighter Handling
The Hanson profile tapers smoothly from the gas block down to the muzzle instead of having that traditional stepped shoulder you see on most barrels. This means you get real weight savings without that wimpy pencil-barrel feeling. The design reduces barrel whip and improves harmonics, so follow-up shots stay consistent and on target. Most builders switching from government profiles immediately notice how much faster the rifle shoulders and how much easier it is to keep steady during extended shooting.
Mid-Length Gas System and Included Gas Block
The mid-length gas system runs cleaner than carbine setups and cycles softer, which matters when you're putting downrange volume. Recoil impulse is noticeably smoother, making follow-ups quicker and easier. The .750" low-pro gas block comes pre-pinned and ready to go. This isn't some loose component you have to worry about aligning perfectly during assembly. The pinned design handles rough handling and high-volume shooting without creeping or shifting.
Cold Hammer Forging and Chrome-Lined Durability
Cold hammer forged construction densifies the steel more than traditional methods, giving you longer barrel life and more consistent velocity shot to shot. The chrome-lined bore means less copper fouling buildup, easier cleaning, and better corrosion resistance. Manganese phosphate finish will patina over time but holds up well and looks right on a duty-focused build. The barrel is HP and MPI tested from the factory, so you know it's built to spec.
This 14.5" barrel handles everything from bulk 55-grain training ammo up through 77-grain match ammunition thanks to the 1:7 twist rate. It threads 1/2×28 for standard muzzle devices.

Frequently Asked Questions
What's the difference between the Hanson profile and a standard government barrel?
The Hanson profile tapers smoothly from the gas block to muzzle instead of having a sharp shoulder, which removes unnecessary weight while maintaining rigidity and accuracy. This design reduces barrel whip, improves harmonics, and gives you a noticeably faster-handling rifle without the drawbacks of ultra-lightweight pencil barrels. You get real weight savings without sacrificing heat capacity or durability.
Is this barrel good for both practice ammo and quality ammunition?
Absolutely. The 1:7 twist rate handles everything from 55-grain FMJ bulk ammo up through 77-grain match loads without issue. The chrome-lined bore makes cleaning easier after high-volume training sessions, and the cold hammer forged construction ensures velocity consistency whether you're running budget stuff or precision ammunition. This barrel does the job across the board.
Does this barrel come with the gas block?
Yes, it ships with a .750" low-profile gas block pre-pinned and installed. That saves you assembly hassle and alignment worries. The pinned design keeps it secure and won't shift during use, which is especially valuable on a mid-length system that runs a bit hotter than carbine setups.
Will I need a muzzle device like a flash hider or suppressor with this barrel?
This barrel is 14.5", so whether you need an attached device depends on your application and local rules. The 1/2×28 thread pattern is standard and works with a wide range of flash hiders, brakes, and suppressors. Many builders use this length when attaching a muzzle device to reach a specific total length.
