The Scalarworks SYNC Mount allows for a near-seamless integration between your Aimpoint ACRO and Beretta 1301 shotgun. The SYNC mount puts the optic's dot reticle at the ideal shooting position allowing for intuitive target acquisition. Every Sync mount is precision CNC milled from 7075-T6 billet, which has vastly superior mechanical properties to more common aluminum alloys and is used where strength and durability outweigh cost considerations. From swamp to torrential downpours, the SYNC mount's completely waterproof mounting interface ensures that your weapon system's optics are always in play no matter the environmental conditions.
