204 Ruger Complete Uppers

Why Choose a .204 Ruger Upper for Varmint Hunting?

Achieve unmatched velocity and surgical precision with our AR15 Elite 204 Ruger upper receivers. Engineered for the dedicated varmint hunter and long-range enthusiast, the 204 Ruger caliber is celebrated for its incredibly flat trajectory and minimal recoil. Originating from the 222 Remington Magnum parent case, 204 Ruger saw a signifcant speed advantage over its nearest competitors. Our selection of complete uppers features 416R stainless steel barrels and optimized gas systems designed to maximize the 4,000+ FPS potential of this round.

By integrating a premium 204 Ruger upper with your standard AR-15 lower, you gain a high-speed predator rifle without the need for proprietary magazines or specialized bolt carrier groups. Whether you are bench-shooting for groups or glassing for coyotes, these uppers provide the thermal stability and harmonic accuracy required for sub-MOA performance in the field.

All AR15 Elite AR-15 uppers are American Made and machined by manufacturers of high quality, industry specific, mil-spec AR-15 components.  Every upper we ship is individually checked for headspace using Manson go and no-go gauges prior to shipping to ensure safety and proper function.
