Description
This 16-inch barrel from Wilson Combat gives your .300 Blackout build the kind of precision engineering that's made them a go-to for serious rifle builders. Machined from American-made 416R stainless steel on computer-controlled equipment, it's built to tight tolerances that matter when you're looking for consistent accuracy. The hand-polished bore and feedramps get the same attention you'd see on much more expensive custom work, which is part of why this barrel keeps showing up in builds for everything from suppressed shooting to hunting.
What Makes This 300 Blackout Barrel Work
The 1-7 twist rate is the real workhorse here. It'll stabilize heavy subsonic bullets like the 220 grain loads that make .300 Blackout so appealing for quiet shooting, but you can also run lighter supersonic rounds without any fuss. The pistol-length gas system keeps the platform running clean without requiring an adjustable block if you switch between subsonic and supersonic ammo. Factory threading at 5/8×24 lets you add whatever muzzle device you want right out of the box.
Build Quality That Speaks For Itself
You get the details that separate match-grade barrels from standard production parts. The precision muzzle crown is cut sharp and true, the chamber and gas port are optimized for reliability, and every barrel goes through a rigorous final inspection. The bead-blasted stainless finish keeps things low-glare while resisting corrosion way better than basic steel. Real user feedback shows this barrel printing sub-MOA groups with quality hand loads and working flawlessly with factory ammunition in hunting applications out to practical distances.
A Practical 16-Inch Platform
At 27 ounces, this barrel hits the sweet spot for practical use. It's light enough to handle all day, heavy enough to dissipate heat and maintain accuracy through strings of fire. The 16-inch length gives you decent velocity from subsonic rounds while keeping the overall package compact. Whether you're building for suppressed duty, field hunting, or precision practice, this barrel's designed to work in the real world, not just on paper.

Frequently Asked Questions
What ammunition does this .300 Blackout barrel work with?
This barrel excels with both subsonic (185-220 grain) and supersonic (110-150 grain) ammunition. The 1-7 twist is optimized for heavier subsonic loads but handles lighter factory loads without any issues. You can switch between subsonic and supersonic ammo without needing an adjustable gas block since the pistol-length system balances gas output for both.
Can I use this barrel with a suppressor?
Yes, this is where the barrel really shines. The pistol-length gas system and factory-optimized chamber work great with suppressors, especially paired with subsonic ammunition. The 5/8×24 muzzle threads accept standard muzzle devices and most direct-thread cans. Many users report near whisper-quiet performance with appropriate subsonic loads.
Is this barrel accurate for hunting?
Users have reported consistent sub-MOA accuracy with match loads and around 2-3 MOA with quality factory ammunition, which is plenty for hunting applications. The hand-polished bore and precision crown work together to deliver the kind of precision you'd want in a hunting rifle without requiring excessive load development or tuning.
What makes Wilson Combat's match grade barrels different?
Wilson Combat barrels are machined on computer-controlled equipment with hand-polished bores and feedramps, then put through rigorous final inspection. The attention to tight manufacturing tolerances and precision crown work shows in real-world accuracy, and the 416R stainless construction offers durability and corrosion resistance that lasts.
