Radical Firearms RPR 7.62x39 AR-15 Rifle 16" Barrel M-LOK

The Radical Firearms RPR chambered in 7.62x39mm delivers AK-47 ballistics through an AR-15 platform with enhanced reliability and modularity. This configuration combines the proven stopping power of the Soviet cartridge with the ergonomics and customization options that make the AR-15 America's most popular rifle platform.

What Makes This Different

Unlike standard 5.56 AR-15s, this RPR handles the larger 7.62x39 cartridge through specialized bolt geometry and enhanced extraction systems. The rifle features a properly headspaced barrel extension and modified bolt carrier group specifically engineered for the tapered case design of Russian ammunition. Performance testing shows consistent cycling with both steel-cased and brass ammunition, addressing the reliability concerns that plague many AR-15 conversions to this caliber.
