.224 Caliber, 1:14 Twist – Optimized for Varmint & Light Bullets
This Douglas barrel blank is specifically spec’d for .22 caliber (.223–.224) bullets with a 1:14" twist rate, a classic choice for lighter, high-velocity projectiles: Brownells Österreich+2Brownells Česká republika+2
Caliber: .22 caliber (.223–.224)
Twist Rate: 1:14", ideal for traditional 40–55 grain varmint and small-game bullets
Excellent for building high-velocity .223 Rem / .22-250-style varmint rifles (depending on chambering) focused on explosive on-target performance and flat trajectories
If your goal is prairie dogs, ground squirrels, foxes, or general small-game/varmint work with lighter bullets, the 1:14 twist is a proven winner.
#4 Contour – A Sweet Spot Between Sporter & Heavy
Douglas’ #4 contour gives this blank a medium-heavy profile that’s right at home in real-world rifles: Primary Tactical+2Brownells+2
#4 contour offers noticeably more stiffness than a light sporter barrel, improving consistency as the barrel heats up
Still lighter and more carry-friendly than a full bull barrel, making it perfect for walking varminters, truck guns, and crossover field/bench builds
Package weight from Brownells listings is around 1.6 kg total (shipping), putting the finished barrel in a very manageable mid-weight category for precision field rifles Brownells Schweiz+1
If you want a barrel that can hold tight groups over extended shot strings without turning your rifle into a bench-only beast, the #4 contour is a smart choice.
Douglas Double XX Ultra Rifled – True Match-Grade Quality
Douglas Double XX barrels have earned their reputation by delivering consistent, repeatable accuracy for generations of custom builds: Brownells Österreich+2Primary Tactical+2
Button rifled for exceptionally smooth bores and uniform rifling geometry
Tolerances for groove diameter and straightness held to about 0.0005", which firmly places these in the match-grade category Brownells Österreich+1
Six-groove rifling on all barrels from .22 through .338 caliber, including this .224 model, for proven accuracy and easy load development Brownells Österreich+1

When you start a build around a Douglas Double XX Ultra Rifled blank, you’re giving your rifle the same core quality trusted by experienced custom builders worldwide.
Stainless Steel Construction for Harsh-Weather Durability
The CONTOUR #4 237924144 blank is made from stainless steel, giving you enhanced corrosion resistance and longevity compared to chrome moly: Brownells Österreich+2Crow Wholesale+2
Material: Stainless steel – ideal for rifles that see wet fields, dusty varmint towns, or long days in the truck rack
Excellent resistance to rust and pitting, especially valuable for varmint and predator rigs that may go a bit longer between deep cleanings
Machines cleanly and takes bead-blast, polished, or coated finishes well, so you can match your preferred aesthetic
For a hard-use, all-weather .22-caliber rifle, stainless construction is a big advantage.
Unchambered, Unthreaded – Ready for a True Custom Build
Like any proper barrel blank, this Douglas Ultra Rifled #4 contour arrives unchambered and unthreaded, ready for your gunsmith to tailor to your specific project: Brownells Česká republika+2Primary Tactical+2
Supplied as a match-grade blank, with enough length and diameter for custom chambering and crowning
Lets you choose exactly which .22-caliber cartridge you want—.223 Rem, .22-250, .222, or other .224-compatible rounds (depending on action and gunsmith’s advice)
Gives your smith full control over freebore, throat geometry, finished length, and muzzle work
Important: As with all barrel blanks, this product must be chambered, threaded, and installed by a qualified gunsmith to ensure safe headspace and to realize its full accuracy potential.
