View larger BLS STAINLESS ULTIMATE HEAVY 0.50g airsoft BBs are special very heavy airsoft BBs containing metal powder in a grey finish, designed primarily for precision target and competitive shooting. The package contains 1000 BBs with a diameter of 5.95 mm ± 0.01 mm. Due to their high weight, hardness and significantly higher impact energy, we do not recommend using them in regular games against players.

The WoSporT LEVER / PTS M12 ODIN adapter allows you to load AK AEG mid-cap magazines using WoSporT LEVER / SILENCE / BOTTLE speed loaders or the PTS M12 ODIN. It is a simple way to expand your loader's compatibility beyond the M4 platform. The adapter locks into the speed loader just like an M4 / AR15 magazine.
BLS STAINLESS ULTIMATE HEAVY represent a special category of heavy airsoft ammunition. Unlike conventional plastic BBs, their material contains metal powder, making it possible to achieve an exceptionally high weight while maintaining the standard dimensions of a 6mm airsoft BB. The manufacturer specifies a diameter of 5.95 mm with a tolerance of ± 0.01 mm. The smooth polished surface and dimensional consistency are important for smooth passage through the barrel and reliable feeding. The higher weight is intended primarily for powerful and precisely tuned target airsoft guns whose properly adjusted hop-up can reliably lift such a heavy BB. They can be used in suitable AEG, HPA, gas and manual systems. However, we do not recommend STAINLESS ULTIMATE HEAVY for regular airsoft games or shooting at players. A BB of this weight carries significantly more kinetic energy at the same velocity than a lighter BB, while the addition of metal powder also changes its mechanical properties. The STAINLESS series is therefore suitable only for target and competitive shooting. Users should also expect increased wear on the hop-up bucking and inner barrel. We therefore recommend regularly inspecting and cleaning the barrel after shooting.
They are primarily designed for target and competitive airsoft shooting with powerful and precisely tuned guns. The metal powder content makes it possible to achieve the exceptional weight of 0.50 g while maintaining the standard BB dimensions.
We do not recommend it. STAINLESS ULTIMATE HEAVY BBs contain metal powder and carry high kinetic energy at the corresponding velocity. For safety reasons, we therefore recommend using them for target shooting, not against players.
Yes, faster wear should be expected. Due to the specific composition and properties of these BBs, we recommend regularly inspecting and cleaning the inner barrel and also monitoring the condition of the hop-up bucking.
No. These are special plastic BBs containing metal powder, not part of the biodegradable BLS BIO series.
