Description
The B & T SPR300 Pro Mini .300 Blackout 6.89" Bbl Ti Suppressor SPR Series SBR is an ultra-compact, bolt-action precision system designed for maximum signature reduction in a significantly shortened "Mini" footprint. Engineered as a dedicated subsonic platform, it features a 175mm (6.89-inch) cold-hammer-forged barrel with an incredibly fast 1:5 twist rate to ensure heavy .30 caliber projectiles are fully stabilized even at low velocities. The system includes an updated Pro chassis compatible with standard AR-pattern magazines, a crisp Timney single-stage match trigger, and a side-folding adjustable stock that allows the entire suppressed rifle to be transported in a discreet, small-form factor carry bag. As a complete NFA-regulated solution, the SPR300 Pro Mini combines B & T's legendary Swiss precision with a high-volume titanium suppressor to deliver nearly silent performance, making it one of the most quiet and maneuverable precision tools available for specialized tactical applications.
