Alliant AR-Comp Rifle Powder for AR-15/AR-10 Multi-Caliber 1lb

Alliant AR-Comp powder delivers consistent velocities and clean burning performance specifically engineered for AR-platform rifles. This spherical propellant maintains temperature stability across extreme conditions while reducing fouling in gas-operated systems.

What Makes This Different

AR-Comp features a unique spherical grain structure that meters uniformly through progressive presses and powder measures. The formulation burns cleaner than traditional ball powders, reducing carbon buildup in gas tubes and bolt carrier groups. Temperature stability remains within 0.5 fps per degree Fahrenheit, ensuring consistent performance from sub-zero to desert conditions.

Key Features

• Spherical grain structure for consistent metering and charge weights
• Low flash signature reduces muzzle blast visibility
• Clean burning formula minimizes fouling in gas systems
• Temperature stable across -40°F to 140°F operating range
• Compatible with .223 Remington, 5.56 NATO, .308 Winchester, and 6.5 Creedmoor
• Copper crusher tested pressure specifications ensure safe loading
• 1-pound canister provides approximately 140-160 loads depending on caliber

Competitive shooters rely on AR-Comp for match-grade accuracy in rapid-fire strings where consistent velocities matter most. The powder's burn rate works effectively with bullet weights from 55 to 77 grains in .223/5.56 applications, while heavier calibers benefit from reduced pressure curves. Law enforcement agencies specify AR-Comp for duty rifles where reliability cannot be compromised across varying environmental conditions.
