Easy to Use
Equipped with a reliable gas piston system that can be switched between unsuppressed and suppressed modes, BRN-180s offers an easily adjustable way for this switching. There is also U and an S identifier on the handguard’s hole so you would know what setting you are using.
Swapping between these two modes is made easier too. You can just pull back the piston by hand to compress the spring and lift the cup up and out. The method is simpler and more convenient than rotating a knob.
This is a desirable characteristic since it will be easy for you to change between two modes, allowing the air to pass smoothly through the barrel and to cool down faster which increases your firing rate.
Reliability and Performance
Your shooting skill will greatly improve with this upper receiver assembly. Thanks to its ability to use a .223 Wylde chamber, you can aim and shoot the target more accurately.
This chamber offers a small space between itself and the barrel, which is known as the bore diameter. It only has .2240 bore diameter, which is good for aiming a target. The smaller the space, the more aligned and precise your shooting will be.
Its performance is superb too because it features a three-prong flash suppressor which is used to prevent any muzzle blast from breaking any dust signatures.

For its 10.5-inch barrel, it is made from 4150 carbon steel, making it strong to endure fatigue and stresses. It is then coated with a Nitride finish to make it resistant from corrosion and wear.

Lightweight and Compact
Shooting is way easier without additional paraphernalia that weighs your gun down due to additional, unnecessary weight. Carrying a heavy weapon is not a good idea in the tactical world.
However, this upper receiver assembly offers a very minimal increase to your weapon’s overall load. Weighing a total of 4 pounds, it is lighter than other receiver assemblies. You will still be able to carry your weapon anywhere you go.
You don’t have to struggle to look for a lower receiver since this can get along to any standard mil-spec AR-15 lower receiver. The BRN-180s uses a .223 Wylde for its chamber so you can have the flexibility to choose what ammo you’re going to use.
Its chamber can handle both .223 Remington and military-type 5.56mm NATO ammo safely. This also uses a military-standard Picatinny rail, which is compatible with some mounting methods. So if you’d like to attach a scope for better aiming and shooting, it will be easier for you to do it.
