Ultra Rifled .224 Barrel Blank for .223/.224 Builds
This Douglas barrel blank is purpose-built for .22 caliber (.223–.224) centerfire cartridges, giving you a highly versatile twist rate and bore for modern loads: prod.brownells.com+1
Caliber: 22 Caliber (.223–.224)
Twist Rate: 1 turn in 9" – ideal for a wide range of bullet weights commonly used in .223 Remington and similar .224-caliber cartridges. prod.brownells.com
Style: Ultra Rifled #3 contour barrel blank – designed for custom rebarreling projects where accuracy and consistency matter. prod.brownells.com+1
Whether you’re building a light/medium sporter, precision varmint rifle, or a custom .223 project, this blank gives your gunsmith the raw accuracy potential Douglas barrels are known for. prod.brownells.com
#3 Contour – Ideal Balance of Rigidity and Carry Weight
The #3 contour is a very popular “medium sporter” profile, striking a balance between stiffness for accuracy and reasonable weight for field use: kriegerbarrels.com+1
More rigid than ultralight sporter barrels, helping reduce whip and maintain point of impact as the barrel warms.
Lighter than heavy varmint or bull barrels, making it practical for rifles that get carried as much as they’re shot.
Well-suited to varmint, predator, and general-purpose hunting rifles, as well as practical target builds where you still care about carry weight.
This profile is a great choice when you want a rifle that shoots like a precision gun but still feels at home in the field.
Premium Douglas Double XX Accuracy
Douglas Double XX barrels have earned a long-standing reputation in the custom rifle world, and this blank follows that same formula: prod.brownells.com+1
Button rifled for exceptionally smooth bore finish and consistent groove geometry.
Tight tolerances on groove diameter and straightness, held to approximately 0.0005", helping deliver excellent accuracy potential. prod.brownells.com
Six-groove rifling in .22 through .338 calibers for proven performance across a broad range of bullet designs. prod.brownells.com
Stress-relieved after rifling to minimize warping and maintain stability during contouring, chambering, and extended firing. prod.brownells.com
If you’re investing in a custom barrel, starting with a Douglas Ultra Rifled blank means you’re building on a proven, high-quality foundation.
Chrome Moly Steel – Strong, Durable, and Gunsmith-Friendly
The CONTOUR #3 237224093 barrel blank is made from 4140 chrome moly steel, a go-to material for quality rifle barrels: prod.brownells.com+2Brownells UK+2
Material: 4140 Chrome Moly Steel
Excellent strength and toughness for field, range, and competition use.
Takes traditional blued or Parkerized finishes well, giving you flexibility in final appearance and corrosion protection.
Chrome moly is widely appreciated by gunsmiths for machining, threading, chambering, and finishing, making your build process more straightforward.
Unturned, Non-Threaded Blank for Custom Fit
This Douglas barrel ships as a blank, ready for your gunsmith to finish to the exact configuration you want: prod.brownells.com+2Frisco Guns+2
Barrel Style: Non-threaded, unchambered blank
Unturned dimensions: Factory spec notes that unturned blanks run about .025"–.050" larger in diameter and approximately 1.5" longer than the final listed dimensions, giving your smith room to dial in the perfect contour and length. prod.brownells.com
Can be cut, crowned, threaded, and chambered to your choice of .224 caliber cartridge (e.g., .223 Remington and similar) by a qualified gunsmith.
This flexibility is exactly what you want for true custom builds—bolt-action rebarrels, single-shot rifles, or carefully spec’d AR-platform barrels when contoured and chambered appropriately.
Important: Douglas and retailers specify that barrel blanks should be installed and finished by a qualified gunsmith to ensure safety and optimal performance. Brownells Česká republika+1
Ideal Applications for the CONTOUR #3 Douglas .224 Barrel
Because of its twist rate, contour, and quality, this barrel blank is an excellent choice for:
Varmint and predator rifles in .223/.224, where long strings of accurate shots and manageable weight are important.
Precision hunting rifles, from coyotes to small game, where you want custom chambering, throating, and crown work.
Range and target rifles that benefit from a #3 contour’s extra rigidity without going to full bull-barrel weight.
Custom rebarreling projects where the builder wants a known, premium barrel maker and the flexibility of a blank.
If you’re looking to step up from factory barrels and fully control the specs of your next .224 rifle, this Douglas #3 contour blank deserves a top spot on your shortlist.
