The Auto-Ordnance TAO50 .50 BMG 29″ Bolt-Action Rifle 10rd is a serious long-range heavy-caliber rifle built for shooters who want factory-level accuracy and durability without the custom-gunsmith wait. It comes with a 29″ steel barrel, a patent-pending action design, and a Timney AR-style trigger in a package that includes an Accu-Tac bipod, a Barrett M107A1 10-round magazine, and a custom wheeled hard case. This is a production rifle that’s set up to shoot right out of the box.

Key Features
- 29″ Steel Barrel with 1:15 Twist – The 1:15 rate of twist is optimized for heavy .50 BMG projectiles (600–800 grain) commonly used in long-range target shooting. This means better stability and accuracy at distances past 1,000 yards.
- High-Efficiency Muzzle Brake – The integrated brake reduces felt recoil significantly, letting you stay on target for follow-up shots without the punishing shoulder impact typical of .50 BMG rifles.
- Magpul PRS Gen3 Precision Adjustable Stock – You get a fully adjustable length of pull, cheek riser, and buttpad height. This lets you dial in your fit for prone or bench shooting, which directly translates to better accuracy.
- Timney AR-Style Trigger – Timney triggers are known for a clean, crisp break. This one gives you a consistent pull weight (adjustable from 2.5 to 5 lbs), so you’re not fighting a gritty trigger when you’re trying to hold center at 1,500 yards.
- Includes Accu-Tac Bipod & Barrett M107A1 Magazine – The Accu-Tac bipod provides rock-solid support on uneven terrain, and the Barrett magazine is a proven, reliable design that feeds .50 BMG rounds smoothly. You don’t have to buy extras just to get started.
Who It’s For
This rifle is for the shooter who wants a production .50 BMG that’s ready for long-range target shooting, ELR competition, or heavy-caliber plinking on a private range. It’s also a solid choice for collectors who want a modern bolt-action .50 that doesn’t require a custom build. It’s not a lightweight carry rifle—this is a bench or bipod gun.
Pros & Cons
Pros: Factory-built accuracy with a Timney trigger and Magpul stock; includes bipod and hard case; 10-round magazine capacity is generous for a .50 BMG; patent-pending action design reduces bolt lift effort compared to some competitors.
Cons: At 28 pounds, it’s heavy to haul around—plan on using the included wheeled case for transport. Also, the 29″ barrel means it’s a long rifle, so it may not fit in standard gun safes without diagonal placement.

According to Auto-Ordnance specs, the TAO50’s patent-pending bolt design reduces lift effort by roughly 20% compared to traditional .50 BMG bolt guns, making it faster to cycle during a string of fire. That’s a real advantage when you’re shooting from a bipod and want to keep your cheek weld.
FAQ
Does the TAO50 come with a scope or optics?
No, the rifle does not include a scope. It has an accessory rail (Picatinny-style) on the receiver for mounting your own optics. You’ll need to purchase a scope and rings separately.
Can I use reloaded ammunition in this rifle?
Yes, but we recommend sticking to factory-loaded .50 BMG ammunition for the first 200 rounds to break in the barrel. After that, properly sized and charged reloads are fine, as long as they meet SAAMI specifications.
Is the Accu-Tac bipod included with the rifle?
Yes, the TAO50 ships with an Accu-Tac bipod attached to the forend. It’s a heavy-duty bipod with adjustable legs and tension, so you’re good to go for bench or prone shooting right away.
What is the warranty on the TAO50?
Auto-Ordnance backs the TAO50 with a one-year limited warranty against defects in materials and workmanship. We recommend registering the rifle online after purchase to activate coverage.
Does the 10-round magazine fit other .50 BMG rifles?
The included magazine is a Barrett M107A1 pattern magazine. It will fit Barrett M107A1 and M82A1 rifles, but it’s not compatible with the ArmaLite AR-50 or other bolt-action .50s.
