Rock River Arms Rifle Lowers for Sale

Rock River Arms, Inc. of the United States has focused on rifle lowers since entering AR-pattern lower receivers in 1997, making forged lowers a long-running staple of its LAR-series platforms. Its rifle lowers are distinguished by purpose-built designs that natively accept non‑STANAG magazines across calibers, including Colt SMG, AK‑47, and FAL patterns, without relying on mag‑block conversions, with the standard LAR‑15 lower serving as the base for many factory AR‑15 and law-enforcement configurations.
