Outfit your B&T Factory FDE APC/SPC/GHM with an Aimpoint/B&T OEM FDE ACRO P-2 and 39 mm Skeleton Mount. Fully enclosed design with hardened front and rear class lenses. The Acro P-2 represents the next generation of pistol mounted optics, taking things to an entirely new level. Built to endure the physical demands of semi-automatic pistol slides, the Acro P-2 includes a brighter, more efficient LED emitter coupled with a higher capacity CR2032 battery to provide over 5 years of constant-on use. Designed and tested to withstand the shock, vibration, extreme temperatures and material stresses generated by firing over 20,000 rounds of .40 S&Wammunition, the Acro P-2 goes above and beyond the call of duty.
