Made in Birmingham, England *If you cannot fill your gun to 3-365 psi because your fill device is limited to 3-000 psi output, you can still shoot this air gun. You just won't get as many shots per fill. The SILENTIUM is BSA's latest and most technologically advanced noise reduction system to date. Integrated into the muzzle of each rifle barrel SILENTIUM allows the pellet to pass freely while effectively reducing the majority of noise expansion. This clever new design dissipates significantly more sound than ever before through its internal air chambers, thus suppressing noise expansion up to 82% when compared to standard muzzle report.
