Key Features
- Hand-polished Noveske Match Chamber: This gives you smoother feeding and better case support, which means tighter groups and fewer malfunctions at the range.
- Mid-length gas system: It cuts down on recoil and keeps the bolt cycling smoothly, so you stay on target faster for follow-up shots.
- Extended, hand-polished feed ramps: These ramps reduce the chance of a jam when using different ammo types, especially with hollow points or steel case.
- Noveske KX3 flash suppressor (pinned and welded): The KX3 cuts muzzle flash and keeps the barrel length legal at 16″ overall, so you can run this without a tax stamp.
- Magpul MOE SL stock: It locks up tight, is lightweight, and gives you a solid cheek weld for consistent accuracy.

FAQ
Is the Noveske G4 Infidel legal to own without a tax stamp?
Yes. The 13.7″ barrel has a permanently pinned-and-welded Noveske KX3 flash suppressor, bringing the overall barrel length to 16″. That makes it a legal rifle under the National Firearms Act without any extra paperwork.
What ammunition works best with the Noveske G4 Infidel?
It handles both .223 REM and 5.56 NATO ammo reliably. The hand-polished chamber and feed ramps give you smooth cycling with brass case, steel case, and even some hollow points. For best accuracy, stick with match-grade 5.56 loads.
Can I change the stock or grip on the Noveske G4 Infidel?
Yes. The rifle uses a standard AR-15 buffer tube and pistol grip threads. You can swap the Magpul MOE SL stock for any mil-spec stock, and the grip can be replaced with aftermarket options.
How does the Noveske G4 Infidel compare to a standard AR-15?
The main difference is the hand-polished match chamber and extended feed ramps, which give you tighter accuracy and better feeding. The mid-length gas system also makes it softer shooting than many carbine-length ARs.
