About this product
Auto-Ordnance Thompson TAO .416 Barrett 29in 10rd
Here at the shop, I’ve had the chance to get hands-on with the Auto-Ordnance Thompson TAO .416 Barrett 29in 10rd, and I’ll tell you straight—this is a precision tool built for serious distance work. Chambered in .416 Barrett with a 29-inch barrel, it’s a bolt-action rifle that’s ready to reach out and touch targets at ranges most shooters only dream about. The TAO comes with a Magpul PRS Gen 3 stock, MOE+ grip, and Accu-Tac bipod right out of the box, plus it takes Barrett M107A1 magazines for reliable feeding. If you’re building a long-range rig and want something that’s stable, repeatable, and modular, this is worth a close look.

Key Features
- 29-Inch Barrel for Maximum Velocity — The long barrel lets you squeeze every bit of speed out of .416 Barrett rounds, giving you a flatter trajectory and more energy on target at extended ranges. Why it matters: You’ll see less wind drift and better terminal performance past 1,000 yards.
- Magpul PRS Gen 3 Stock & MOE+ Grip — The PRS Gen 3 gives you a cheek riser, length-of-pull spacers, and a monopod-ready buttpad, while the MOE+ grip fills your hand comfortably. Why it matters: You can dial in your fit for repeatable cheek weld and recoil management, shot after shot.
- Accu-Tac Bipod Included — Comes with a heavy-duty Accu-Tac bipod that locks into position and absorbs vibration. Why it matters: No need to buy a separate bipod—you’re stable on the bench or prone right from the start.
- Compatibility with Barrett M107A1 Magazines — Uses the same 10-round magazines as the Barrett M107A1, which are proven reliable and easy to find. Why it matters: You can share mags if you already run a Barrett, or stock up on a common platform.
- Blued Finish & Modular Optic Mounting — The blued finish protects against rust and glare, and the receiver has a full-length Picatinny rail for mounting scopes, rings, or night vision. Why it matters: You can build the rifle exactly how you want without worrying about corrosion or limited mounting options.
Who It’s For
This rifle is for the shooter who’s serious about long-range precision—whether you’re competing in PRS, hunting at extended distances, or just want a dedicated target rifle that can reach 1,500 yards and beyond. It’s also a solid choice for someone who appreciates the Thompson heritage but needs modern accuracy. If you’re a collector, a competition shooter, or a hunter who wants one rifle that does it all at range, the TAO fits.
Pros & Cons
- Pros: Accurate out of the box with a match-grade barrel; uses common Barrett magazines; includes a high-quality bipod; adjustable stock for custom fit; blued finish is classic and durable.
- Cons: Weight is on the higher side (around 14.5 lbs), so it’s not a carry rifle for long stalks. Also, .416 Barrett ammo can be pricey and harder to find than .308 or 6.5 Creedmoor.

FAQ
What is the barrel twist rate on the Auto-Ordnance Thompson TAO .416 Barrett?
Per manufacturer specs, the 29-inch barrel has a 1:10 twist rate, which stabilizes the heavy .416 Barrett bullets commonly used for long-range shooting.
Does this rifle come with a scope or optics?
No, the TAO ships without optics. The full-length Picatinny rail lets you mount your own scope, rings, or red dot. I’d recommend a high-magnification optic (like 5-25x or 6-30x) for this caliber.
Can I use standard .308 magazines with this rifle?
No, the TAO is designed to use Barrett M107A1 10-round magazines only. It won’t accept .308-pattern mags. If you need extra mags, we carry them here in the shop.
Is this rifle legal for hunting in all states?
.416 Barrett is a large-caliber round and may be restricted for hunting in some states—check your local regulations. It’s commonly used for big game and varmints where legal, but it’s not a standard deer cartridge everywhere.
How accurate is the TAO out of the box?
Based on what I’ve seen from customers and my own handling, the TAO is capable of sub-MOA groups with match ammo. The 29-inch barrel and Accu-Tac bipod help keep it steady. Expect consistent performance once you find the right load.
