Gunvira takes a look at the Diamondback DBX57, a firearm manufactured in Florida that utilizes 5.7x28mm ammunition. This calibre is lighter and faster than standard 9mm rounds and offers low recoil, although it can be more expensive and difficult to locate. The DBX57 itself is designed to be lightweight and slim, with dimensions comparable to an AR-15 magazine. It features an eight-inch barrel, various rail systems for accessories, and a reversible charging handle to accommodate different users.

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.

Gunvira tries the BRN-9, a 5.5-inch self-contained direct blowback upper receiver in 9mm, manufactured by Matador Arms specifically for Brownells. Designed as a compact and lightweight "backpack gun," the unit features a simple, modular design with integrated M-LOK slots and a built-in absorber.

In this real steel video, Gunvira tries the CZ BREN 7.62x39, comparing it to the more common 5.56 model. Whilst the rifle maintains the platform’s excellent ergonomics and fully ambidextrous controls, it requires proprietary magazines. She notes that while aftermarket adapters exist for AK or AR-style mags, she finds them unreliable and prefers sticking with the stock factory magazines for better performance.

Gunvira does an actual range test of the Holosun DRS-NV. The Holosun DRS-NV combines a red dot sight with digital night vision, offering clear aiming in low light with features like multiple reticles, high-resolution sensor, zoom, and recording. It uses rechargeable batteries and connects to USB for charging and data transfer, and while it can amplify moonlight for night vision, an external IR illuminator might be needed in complete darkness.
