Introduction

I’ve been hearing a lot about the .277 Fury round and its potential applications in upper receivers for AR-10 style rifles. I’m intrigued by its performance and the technology behind it, but I have some questions and would love to get the community’s input.

What is the .277 Fury?

The .277 Fury, developed by SIG Sauer for the U.S. military’s Next Generation Squad Weapons program, is said to offer impressive ballistics and terminal performance. It’s designed for modern combat scenarios, and it seems to have a mix of capabilities that could interest civilian shooters.

Upper Receiver Compatibility

  • Current Options: I’m curious about what upper receivers are available specifically for the .277 Fury. Are there specific brands or models that stand out?
  • Conversion Kits: For those of us who already own AR-10 rifles, are there conversion kits available to make the switch to .277 Fury? How seamless is this process, and are there any particular challenges to watch out for?

Performance Insights

  • Accuracy and Range: How does the .277 Fury perform compared to more traditional calibers like .308 or 6.5 Creedmoor? What’s everyone’s experience in terms of accuracy and effective range?
  • Ammunition Availability: Are there any concerns regarding the availability of .277 Fury ammunition for civilian use? I don’t want to invest in an upper receiver only to find it hard to source ammo later.

Conclusion

I’m looking to build or upgrade my rifle system, and I believe the .277 Fury could be an excellent choice. Any advice, experiences, or recommendations would be greatly appreciated! Let’s discuss all things .277 Fury!

I recently installed the .277 Fury upper receiver and it was quite an experience! I recommend having a solid vice and the right torque wrench. Always double-check your alignment.

16

Great tips, Kevin! I found that using a molybdenum grease on the bolt carrier group helped with smoother operation. Has anyone else tried that?

17

I agree with Kevin on the importance of a good torque wrench. I struggled a bit with the gas block alignment—any advice on that?

18

Andrew, I had the same issue! I found it helpful to use a laser alignment tool, it made everything so much easier.

19

For gas block alignment, it’s crucial to have patience. I used a simple Allen key to help ease it into the right spot before tightening.

As for tools, I’ve also successfully used a combination of screwdrivers and punches. Just be sure to avoid using too much force—it could damage the components!
