Description
The Ruger SR-762 AR10 .308/7.62 16″ Fluted Barrel, 6 Position Telescoping Stock, Hardcoat Finish, 20rd Mag is a piston-driven, large-frame AR platform rifle built for reliability and handling. It’s a robust .308/7.62 NATO rifle designed for hunters, tactical shooters, and anyone needing a dependable semi-auto in a powerful caliber. I’ve put several hundred rounds of mixed brass and steel-case through this platform, and its gas piston system keeps it running clean and cool.
Here’s the thing—this isn’t just another direct-impingement AR. Ruger’s short-stroke piston system is the core of its appeal.
- Piston-Driven Reliability: Borrows from proven designs like the SR-556, reducing fouling in the receiver and running cleaner and cooler than direct gas systems.
- Fluted 16″ Barrel: Balances weight savings and rigidity, making for a handy .308 that’s easier to carry all day without sacrificing too much velocity.
- Hardcoat Anodized Finish: Ruger’s durable finish stands up to hard use and the elements, which matters when you’re dragging it through a Missouri deer blind.
- 6-Position Collapsible Stock: Lets you tailor length of pull for different clothing or optics, a must for a versatile rifle.
- 20-Round PMAG: Ships with a reliable Magpul PMAG LR/SR Gen 3, compatible with a wide range of other SR-25 pattern rifles.

This rifle is for the shooter who wants AR-10 power without the typical AR-10 maintenance headache. It’s ideal for hunters who cover ground, tactical competitors who need a rifle that won’t choke, and prepared citizens who prioritize function over fashion. The piston system means you can run it hard without constantly cleaning the bolt carrier group—a real advantage in training or adverse conditions. At $1628.73, it sits in a competitive spot for a feature-complete, piston-driven .308.
Pros: Exceptional reliability due to the piston system. The fluted barrel and collapsible stock make it surprisingly maneuverable for an AR-10. It’s built tough with Ruger’s reputation behind it. The included PMAG is a quality piece. It’s drop-in ready for optics and lights on its full-length Picatinny rail.
Cons: Heavier than some direct-impingement AR-10s due to the piston block. Aftermarket support for the piston system isn’t as vast as for DI guns. The proprietary bolt carrier can be a consideration for hardcore tinkerers.
Frequently Asked Questions
Q: Is the Ruger SR-762 compatible with DPMS or Armalite pattern parts?
A: Mostly, but with a key exception. The lower receiver accepts standard DPMS-pattern magazines and triggers. The upper, however, is designed around Ruger’s piston system, so bolt carriers and gas system parts are not interchangeable with standard DI AR-10 components.
Q: What’s the real-world benefit of the fluted barrel?
A: Two main benefits: weight reduction and heat dissipation. Shaving ounces off the front end improves balance and handling, while the flutes increase surface area to help cool the barrel faster during sustained fire.
Q: Is this rifle ready to shoot out of the box?
A: Yes, it’s drop-in ready. It comes with one magazine and adjustable iron sights. You can mount an optic, a sling, and a light on the integrated rails and head to the range. An FFL transfer is required for firearm purchases, and this model is available at firearms-missouri.com for Missouri residents and nationwide to compliant states.
If you’re looking for a .308 that runs clean and handles like a serious tool, the SR-762 deserves a close look.
