Description
There are only a handful of .50 BMG bolt guns on the market, and Auto-Ordnance clearly did their homework before jumping in. The TAO50 is built around a 29 inch precision barrel with a 1:15 twist, the sweet spot for stabilizing heavy .50 caliber projectiles at serious distance. The muzzle is threaded 1×14 TPI and capped with Auto-Ordnance's patent-pending high-efficiency brake, and that brake is the story here. Kahr Firearms Group set out to build one of the softest recoiling .50s available, and range reports back that up. For a cartridge with this much energy, the push is far more manageable than you'd expect.
What Makes the TAO50 Different
The bolt rides on a patent-pending roller bearing system with a left-side handle, so your firing hand stays on the grip while you cycle. Fire controls are AR-style, including an ambidextrous safety and a Timney drop-in trigger built specifically for .50 BMG, which means anyone comfortable on an AR platform will feel right at home. Smart move on the magazine too: instead of a proprietary design, the TAO50 feeds from Barrett M82/M107A1 pattern 10-round mags, which are widely available and thoroughly proven. One comes with the rifle.
Set Up for the Long Game
Furniture is quality stuff you already know. The Magpul PRS Gen 3 stock gives you tool-free length of pull and comb height adjustment for a proper cheek weld behind big glass, and the MOE+ grip keeps things comfortable through long sessions. A full-length rail up top handles optics and accessories, and the included Accu-Tac bipod is a genuinely nice touch at this level. The whole package runs 25.5 pounds, which is right where you want a .50 for stability on the line.
Bringing the TAO50 Home
Everything arrives in a custom wheeled hard case, so transport is sorted from day one. Whether you're chasing steel at a mile or just want the biggest thumper on the range, this one delivers.

Frequently Asked Questions
What magazines does the Auto-Ordnance TAO50 use?
The TAO50 feeds from Barrett M82/M107A1 pattern 10-round box magazines, and one comes with the rifle. That was a smart design choice, since these mags are proven, easy to find, and you're not stuck hunting down a proprietary magazine for an uncommon platform.
How bad is the recoil on the TAO50?
Much softer than you'd expect from a .50 BMG. The patent-pending high-efficiency muzzle brake does a ton of work, and the 25.5 pound weight soaks up the rest. Auto-Ordnance considers it one of the softest recoiling bolt-action .50s on the market, and folks who have run it tend to agree it's surprisingly comfortable.
Can I put a suppressor on the TAO50?
Yes, the muzzle is threaded 1×14 TPI, which opens up compatibility with .50 BMG rated cans from makers like Innovative Arms, Elite Iron, B&T, and HUXWRX. Just make sure whatever suppressor you choose is rated for bolt-action .50 BMG use.
Does the TAO50 come with an optic or iron sights?
No sights or glass are included, but the full-length top rail is ready for whatever optic you want to run. Plan on quality long-range glass and rings or a mount rated for .50 BMG recoil. The included Accu-Tac bipod and adjustable Magpul PRS stock have the support side covered out of the box.
