Whether you’re building a light precision hunting rifle or a general-purpose long-range rig, this blank gives you the core accuracy potential Douglas is known for.
#3 Contour – Balanced for Field and Bench
The #3 contour is a popular “medium sporter” profile that balances rigidity and carry weight:
Stiffer than ultra-light sporter barrels, helping maintain point of impact and consistency as the barrel heats under extended strings of fire.
Lighter than heavy varmint or bull contours, making it very practical for rifles that will be carried in the field as well as shot from the bench.
Ideal for hunting, varmint, predator, and practical precision rifles where you want real-world accuracy without a cumbersome front end. Brownells Österreich+1
At roughly 2.85 lb in raw blank form, this contour offers an excellent weight-to-performance ratio once finished to your desired length. Frisco Guns+1
Douglas Double XX Quality – Button Rifled, Match-Grade Tolerances
Douglas Double XX barrels have a long, proven track record in the custom rifle world, and this blank is built to that same standard:
Button rifled for extremely smooth bore finish and consistent rifling geometry. Brownells Sverige+1
Groove diameter and straightness held to approximately 0.0005", giving the blank true match-grade potential. Brownells Sverige+1
Six-groove rifling for .22 through .338 calibers (including this 6.5mm), a proven configuration for accuracy across a wide range of bullets. Brownells Sverige+1
Stress-relieved after rifling so the blank stays stable during contouring, chambering, threading, and heavy firing. Brownells Sverige+1
If you’re investing in a custom build, starting with a Douglas Ultra Rifled blank means your project begins with a barrel capable of outstanding precision.
4140 Chrome Moly Steel – Strong, Durable, and Finish-Friendly
The CONTOUR #3 237264093 blank is made from 4140 chrome moly steel, one of the most trusted materials for quality rifle barrels: Brownells UK+2Frisco Guns+2
Excellent strength and toughness for hunting, competition, and high-volume range use.
Takes traditional blued, Parkerized, or other protective finishes very well, giving you a range of aesthetic and corrosion-resistance options.
Widely favored by gunsmiths for its machining characteristics when chambering, threading, and crowning.
For a hard-use 6.5mm rifle that still demands precision, chrome moly is a proven, gunsmith-friendly choice.
Unchambered Blank – Maximum Flexibility for Your Gunsmith
This Douglas barrel ships as a true blank, allowing your gunsmith to tailor it exactly to your build:
Unchambered and non-threaded – ready for your choice of 6.5mm cartridge and muzzle configuration. Brownells UK+1
Sold as a #3 contour blank with slightly oversize dimensions, giving the smith room to finish to your preferred overall length and final contour while maintaining proper shoulder and muzzle geometry. Brownells Sverige+1
Perfect for bolt-action rebarrels and other custom rifle projects where you want complete control over chamber, throat, and crown.
Important: As with all barrel blanks, installation and finishing must be performed by a qualified gunsmith to ensure safety, reliability, and accuracy. Brownells Sverige+1
