The legs can be extended into nine different height options. Its wider center hub delivers more stability and strength to support larger heavy rifles.FeaturesDesigned for the 50 BMG caliber platformsAccu-Tac's Heavy Duty and most robust bipodThe arm lock lugs are larger to withstand the heavy recoil of a 50 BMGAbility to cant and has a very sturdy throw leverLever allows you to adjust the tension and enhance the ability to lock the canting motion into placeLegs can be extended into nine different height optionsWider center hub delivers more stability and strength to support larger heavy rifleThe rail mount is simple, quick...
