New videos and reviews every day 6000+ reviews from our customers We first saw Black Bunker at the IWA2023 trade fair, where they presented their revolutionary break‑barrel air rifle with a folding mechanism for the first time.
But this is definitely not where the BM8 model ends – it was actually created for survival purposes in harsh environments. It starts with the use of the classic break‑barrel loading system, just like we know from old Slavia rifles. Instead of a traditional spring, however, it features an advanced gas RAM piston, which ensures high power while reducing vibration and recoil when shooting.
The air rifle therefore requires no additional accessories such as expensive PCP compressors or a stock of disposable CO2 cartridges. Likewise, the manufacturer avoided using a magazine system, as we know for example from modern Gamo air rifles, in order to achieve maximum reliability. Last but not least, the air rifle is almost entirely covered with a durable polymer, again with regard to easy maintenance and better protection of key components. The emphasis on survival use is clearly visible.
As standard, the rifle is fitted with fixed iron sights mounted on the barrel. For mounting a riflescope there is a standard 22mm Weaver / Picatinny rail, and if you want to upgrade the air rifle with a laser, flashlight or bipod, there are two additional removable rails located on the sides of the forearm.
The BM8 model is divided into 3 movable parts – a classic break‑barrel, the main block, and a folding stock. After loosening one rotary safety at the barrel and a second push‑button safety above the stock, both parts are released and can then be folded into a triangular shape. The rail that originally serves to compress the piston when the barrel is broken now has the function of a safety in the folded state, engaging in a slot hidden in the stock.
The package also includes a practical waterproof case for small accessories or ammunition, which fits perfectly into the folded air rifle, and a cap protecting the muzzle and breech from dirt.
We always like to see airgun manufacturers trying to come up with something new, original and innovative. And the BM8 air rifle is exactly such a case. The folding mechanism is ingeniously designed, nothing rattles or wobbles, and the air rifle as a whole feels robust. Simply put, it is a fully fledged (and powerful) break‑barrel with several extra upgrades.

Cheap, robust, lots of power, hits at 50m with the right ammunition 5×5cm
square (but for me only with JSB Exact 4.50mm and 4.51, all heavier Monster,
Beast, or Slugs were almost useless and had a much larger spread circle… ⇒
anyway buy a „JSB Exact Test for Rifle 4.5mm 350St. – Ammunition Kit“ and
test it yourself // Sight mount on the receiver instead of on the barrel … .
no idea what they were thinking … ¯\_(ツ)_/¯

I haven't tried the product yet because the package only included instructions
in English. I don't have internet, I had to go to a friend's house to watch
the instructional video. I understood from the English instruction pamphlet
that the rifle needs to be oiled occasionally, but there is no mention of this
in the video. A Slovak/Czech manual would be useful.
