The Black Bunker BM8 Air Rifle 4.5mm/5.5mm Caliber Tan/Black is powered by a gas ram system, offering several advantages over traditional spring systems, including consistent velocity, less recoil, increased accuracy, reduced noise, less maintenance (no lubrication of spring needed), no spring fatigue, easy cocking, and increased durability.

To ensure user safety and prevent potential damage to the gas ram system, the action of the air rifle can be disengaged by a rapid 2-stage process with a push button and a selector switch, rendering it non-functional.

The BM8 comes with a Picatinny rail system for scope mounting and Picatinny rails on the sides for attaching accessories such as flashlights, lasers, and bipods. An optional configuration includes a multi-purpose knife that can be fitted as a bayonet at the end of the barrel. The first-generation knife fits in the custom case delivered with the air rifle and will be available as a stand-alone item.

The Black Bunker team is already working on the development of complementary products and next-generation models, which will be introduced continuously. With the BM8, Black Bunker has set a new standard for survival air rifles, combining innovation, durability, and practicality in a single product.

Foldable design:

When we saw the Black Bunker BM8 at IWA 2023, we wondered how they did this. Now that we have it in our hands, it is clear that it is a functional, smart, sturdy, but above all, simple design.

With a simple lever, you disconnect the cocking arm, and you can fold the rifle without cocking it. Secure the barrel in the folding stock, and now the BM8 is easy to transport or store.

Then you click the barrel loose from the stock, extend the rifle and re-tighten the cocking arm. This takes less than a full second, and your rifle is ready for use.

Power

The Black Bunker BM8 has a stout power of 24 joules in 5.5mm (.22). This is a popular power class that provides enough power but is still easy to cock and shoot. The BM8 is able to generate this force with a gas ram/piston. In contrast to the traditional coil spring, it shoots and cocks much more smoothly.

Accessory & Optics rails

The BM8 also has 22mm rails on the sides of the stock for mounting accessories. This allows you to easily mount the AG-3 2-piece bipod for a stable shot.

On top of this air rifle, there is a 22mm rail for optics. This allows you to easily mount your favourite rifle scope. Don’t have this yet? No problem! The BM8 is equipped with a set of very good iron sights.

Threaded muzzle

What is not yet visible in all photos is that this air rifle is equipped with 1/2unf threads on the barrel. This allows you to easily install a suppressor/silencer such as the NGS-60.
A break-barrel rifle is difficult to silence due to the mechanism (which is the loudest for the shooter), but a good silencer will significantly reduce the muzzle blast at the barrel!

In short, the Black Bunker BM8 is a very interesting air rifle that not only has an innovative feature, but the general functional quality has clearly also been considered.
