Gunvira features the Brownells BRN-4, an American-made option for those who want the style of an HK416 without the high price tag. It utilizes a short-stroke piston system and was developed with input from industry professionals to ensure it functions as intended. It is available in several barrel lengths and weights, so you can choose how much of a workout you want while at the range.

The rifle features a raised receiver to fit the piston components and a Faxon barrel for accuracy. In this specific setup, it is paired with a colorful rail and a folding stock. While the configuration is heavier than a standard AR, the added mass helps keep the shots steady, even if your shoulders might disagree after a long day of carrying it.

Range testing shows the firearm handles a suppressor effectively, particularly with a flow-through design that manages gas well. She mentions that using the rifle makes her feel like a member of a specialized tactical team, which helps with the morale of shooting in cold temperatures. It cycles through rounds without issues, proving to be a functional alternative for fans of the platform.
