What’s Included
- One 20-round steel metric FAL-pattern magazine
The 26" air-gauged, cryo-treated stainless bull barrel delivers exceptional stiffness and thermal stability, helping the rifle hold its factory 1-MOA guarantee when paired with match-grade ammunition.
A free-float knurled aluminum handguard provides unobstructed barrel harmonics and plenty of surface area for a solid support-hand grip. The round profile keeps weight balanced while protecting the barrel.
The two-stage match trigger breaks cleanly, improving shot-to-shot consistency for target, varmint, or competition use. Combined with the fixed black polymer stock and Hogue rubber over-mold pistol grip, the rifle offers a steady, comfortable shooting platform.
Unlike standard AR-10s, the LAR-8 series feeds from metric FAL magazines—an advantage for shooters who already own FAL mags or want cost-effective, widely available spares.
Rock River Arms produced the Varmint A4 in more limited numbers than its standard LAR-8 rifles, making this example a desirable find for enthusiasts who appreciate accuracy-focused builds straight from the factory.
