Outdated Product
The multishot air rifle from the Optima brand, released in 2025, can be considered a solution at the intersection of the middle and advanced class. The model is likely to interest experienced and demanding shooters, participants in sports shooting competitions, and so forth. One of the main features of the "air gun" is the pre-charging system — there is a special reservoir under the barrel with a volume of 255 cm³, which, when fully charged, allows up to 70 shots. Ammunition consists of the usual 4.5 mm caliber pellets, and the rate of fire is primarily ensured by the standard 10-round magazine and the practical bolt action, which closely resembles mechanisms found in real firearms. The Optima BT65 SB 4.5 air rifle belongs to the category of powerful solutions, as the initial bullet speed...can reach 380 m/s. For increased shooting accuracy, the rifle features a rifled barrel with a length of 58.5 cm. The model's advantages include well-thought-out ergonomics: the stock is made from reliable polymer materials, resistant to temperature changes and high humidity. In addition to textured grips on the stock and pistol grip for convenient hold, there is an adjustment for the cheekpiece and butt, allowing you to literally adapt the model to your own anthropometry. Additionally, there is a Quattro Trigger adjustment mechanism, forearm with accessory rails, sling swivels for gun sling attachment, manual safety, and mount for an optical sight (plus traditional rail and front sight). The match of power and precision ensures unparalleled performance, while the robust 255 cm³ reservoir and advanced ergonomics significantly enhance user experience.
