Description
The Vanguard action has been earning its keep for over five decades, and the Obsidian in 223 Rem takes that proven platform and trims it down to a 16 inch barrel that begs for a suppressor. The muzzle comes threaded 1/2×28 from the factory, so screwing on a can or brake takes about thirty seconds. With a suppressor attached, the shorter tube keeps the overall length manageable instead of turning your rifle into a pole vault, which matters when you are working out of a truck window or a cramped blind on a prairie dog town.
Sub-MOA Accuracy Backed by Weatherby
Every Vanguard Obsidian carries Weatherby's Sub-MOA guarantee, meaning a three shot group of .99 inches or better at 100 yards with Weatherby factory or premium ammo. The cold hammer forged barrel with a 1:9 twist stabilizes a wide range of 223 bullet weights, and the adjustable two-stage match trigger can be dialed down to a crisp 2.5 pounds. Pair those with the M16 style extractor and a smooth 90 degree bolt throw and you have a rifle that runs like guns costing quite a bit more.
Built for Weather, Styled in All Black
The Obsidian wears a black polymer Monte Carlo stock with a raised comb that lines your eye up naturally behind a scope, and it shrugs off rain, mud, and temperature swings that would have a walnut stock swelling and shifting your zero. The barrel, receiver, bolt, and safety are all blued for a clean, murdered-out look that matches the name.
Setting Up Your Vanguard Obsidian 223
The receiver comes drilled and tapped with no iron sights, so plan on adding bases and a scope. The 5+1 capacity feeds from an internal magazine, and the 3-position safety lets you cycle the bolt to unload with the trigger still locked out, a genuinely useful touch at the bench or climbing in and out of a stand. For coyotes, steel plates, or quiet suppressed plinking, this compact Vanguard covers a lot of ground.

Frequently Asked Questions
Is the Weatherby Vanguard Obsidian really guaranteed to shoot Sub-MOA?
Yes. Weatherby guarantees every Vanguard will print a three shot group of .99 inches or less at 100 yards when fed Weatherby factory or premium ammunition. The cold hammer forged barrel and adjustable two-stage trigger do most of the heavy lifting, and plenty of owners report beating that number with handloads or match ammo.
What is the thread pitch on the Vanguard Obsidian 223 barrel?
The muzzle is threaded 1/2×28, which is the standard pattern for .223 and 5.56 suppressors and muzzle devices. That means nearly any rimfire-rated-and-up .22 caliber centerfire can or brake will spin right on without an adapter.
Does this rifle come with sights or a scope?
No, the Obsidian ships without sights. The receiver comes drilled and tapped from the factory, so you just need to add a set of bases or a rail and mount your preferred optic. Most buyers set these up with a mid-power variable scope for varmints and target work.
Does the Vanguard Obsidian use a detachable magazine?
No, this model feeds from an internal magazine with a 5+1 capacity. The 3-position safety is a nice companion to that setup, since the middle position lets you work the bolt to unload the rifle while the trigger stays blocked.
