Rock River Arms announced an upgrade to the company’s varmint rifles. The new rifles now use a proprietary free float handguard called the Top Rail Octogonal or TRO.
The TRO design allows for better airflow around the barrel for cooling and more options on the placement of accessory rails. The rifles are available in right- and left-hand models.
Barrel lengths of 16″, 18″, 20″ and 24″ are available. The guns have .223 Wylde chambers.Related
