NIB BERETTA 391 EXTREMA 12GA/28"BBL/SYN STOCK-KO.In the relentless pursuit of excellence, our engineers have once again set the benchmark for a “do-it-all” shotgun in the form of the new Xtrema2. The Xtrema2 features: Soft shooting gas operation; An integrated spring-mass recoil reducer; Optima-bore overborred barrel; Kick-off recoil reduction. This new shotgun features Aqua technology for extreme environmental protection. All internal and external metallic components are constructed of advanced corrosive resistant materials. This means that even the coastal salt-spray that would ruin a traditional shotgun on a waterfowl outing will not damage this gun.
