B&T SPR 300 Pro — Black Bolt‑Action Spring Sniper (6mm)
The B&T SPR 300 Pro Black is a licensed, integrally‑suppressed style bolt‑action sniper replica built for precision, stealth and realism. Designed to mirror the feel and handling of the original Brügger & Thomet platform, this airsoft variant uses premium anodised aluminium and reinforced polymer parts for a realistic yet lightweight rig that breaks down for easy transport.
Out of the box the SPR 300 Pro comes configured for long‑range accuracy: a 300 mm precision inner barrel, a 45cc air cylinder and CNC piston/steel trigger components combine to deliver consistent, repeatable shots with an advertised energy around 2.8 J (≈551 FPS with 0.20 g BBs). The rifle accepts both a 50‑round box magazine style and VSR‑spec magazines for flexible feeding options.
Ergonomics and modularity are strong points — the folding stock (with adjustable cheek rest), AR‑style pistol grip, QD sling slots and a bottom Picatinny for bipods make the SPR 300 Pro adaptable to field setups. The rifle’s dual‑magazine compatibility and upgrade potential (springs up to M170) also let players tune power and range for field rules or target practice.
Built for hobbyists who want a realistic bolt‑action sniper platform, the SPR 300 Pro balances durability and precision. It’s an excellent choice for skirmish snipers and target shooters who prioritise a solid out‑of‑box experience with room for internal upgrades.
