Comparing the Top 3 AR Deflector Brands

Tired of hot brass flying in your face or disappearing into oblivion? Fellow gun enthusiasts, the struggle is real! But fear not, for the battle against wayward casings is fought not with bullets, but with brass deflectors. Today, we’re putting three popular brass deflectors under the comparison microscope: Brass Bully, Deflector Brake Kit, and Johnson Customs Brass Deflectors. Each has its unique features and potential drawbacks, and we’re here to dissect them all.

Whether you’re a seasoned shooter or a newcomer to the sport, understanding the nuances of these products is key to making an informed decision. Let’s explore what each of these contenders brings to the table, starting with an introduction to their key characteristics, followed by a detailed analysis of their pros and cons.

What is a Brass Deflector?

A brass deflector is a small, handy device attached to a firearm, usually near the ejection port. Its main job? To redirect spent casings (brass) away from the shooter and into a specific area. This is especially helpful for left-handed shooters and keeps the brass from scattering, making clean-up easier and preserving the brass for reloading.

Difference Between a Brass Deflector and Brass Catcher

While both aids in managing ejected casings, a brass deflector and a brass catcher serve different purposes. A brass deflector redirects the casings to a predictable area. It’s about guiding the brass away. In contrast, a brass catcher actually catches and collects the ejected casings in a bag or container attached to the firearm. So, while deflectors guide, catchers collect.

Benefits of Having a Brass Deflector

Owning a brass deflector has several advantages. It enhances safety by preventing hot casings from hitting the shooter, especially useful for left-handed users. It also keeps the shooting area tidy by limiting the spread of ejected casings, making clean-up easier. For those who reload, it helps in collecting casings efficiently. Finally, it minimizes distractions, allowing shooters to focus more on their targets.
