Key Features of the 20” .350 Legend Stainless Barrel Upper

Let’s dive into what makes this upper so attractive.

Barrel Length and Caliber

At 20 inches, the barrel provides excellent velocity for the .350 Legend—a cartridge specifically designed for hunters needing straight-walled ammo with real stopping power.

Heavy Contour Barrel Design

The heavy contour ensures improved accuracy and heat resistance. This is essential when putting multiple rounds downrange without affecting performance.

Twist Rate and Threading

The 1:16 twist rate stabilizes heavier bullets with ease. Add in the 5/8×24 thread, and you’ve got compatibility with a range of muzzle devices or suppressors.

Premium Build Materials

Forged 7075 T6 Aluminum Upper

This isn’t just any upper—it’s forged from 7075 T6 aluminum, offering exceptional strength without extra weight.

Type 3 Class 2 Hard Coat Anodizing

This finish isn’t just for looks. It’s MIL-STD 8625 Type 3 Class 2, providing resistance to wear, corrosion, and abuse.

Advanced Rail System

16.5″ Free Float M-LOK Rail

Engineered from 6061 T6 aluminum, the free float rail ensures your barrel can flex naturally while still providing a solid grip and mounting options.

Lightweight yet Rugged

Despite its length and functionality, it remains light and easy to handle—ideal for long hunting days or extended tactical sessions.

Full-Length M-LOK Attachment Points

Positioned at 12, 3, 6, and 9 o’clock, these slots allow you to mount optics, lasers, lights, or grips precisely where you want them.

Ergonomic Advantages

The narrow profile adds a layer of comfort, making it easier to maneuver your rifle in tight quarters. Your hands will thank you after a long day at the range or in the field.

Gas System and Block

Carbine Length Gas System

The carbine-length gas system ensures reliable cycling without excessive recoil, even with the powerful .350 Legend round.

0.750” Low Profile Gas Block

It keeps your upper looking clean and tactical, while ensuring consistent gas flow and performance.

A2 Flash Hider Explained

A classic for a reason. The A2 flash hider directs gases upward to reduce muzzle rise and visible flash, helping you stay on target.

Crush Washer Installation

Simple installation with a crush washer ensures a tight and reliable fit. No special tools needed—just twist and go.

Compatibility and Customization

Fits with any Mil-Spec AR-15 lower, making it a plug-and-play upgrade. Whether you’re building your first rifle or upgrading your tenth, this upper drops in easily.

Hunting and Tactical Applications

This upper transforms your rifle into a mid-range powerhouse. Whether you’re hunting hogs or clearing targets, you’ll enjoy its balance of power and precision.

Why Choose .350 Legend?

It’s fast. It’s legal in restricted states. And it hits hard. With muzzle velocities around 2,200 fps, it’s perfect for medium game and won’t leave you wanting more knockdown power.

Real User Feedback

Users report smooth cycling, reduced recoil, and pinpoint accuracy. Whether you’re popping paper at the range or bringing home game, this upper delivers.

Maintenance and Longevity

Keep the stainless barrel clean with a bore snake and some CLP. Wipe down the anodized parts occasionally, and this upper will last a lifetime.

Pricing and Value

With all these features, you’d expect a steep price. But it’s surprisingly affordable, offering more value than many custom builds costing twice as much.

Where to Buy

Stick with reputable firearm retailers. Look for clear product descriptions, warranty info, and verified reviews. Avoid third-party sellers without a track record.
