This "Bigfoot" bi-pod is our most heavy duty and most robust bi-pod. The arm lock lugs are larger to withstand the heavy recoil of a 50 BMG. This bi-pod has the ability to cant and has a very sturdy throw lever. The lever allows you to adjust the tension and enhance the ability to lock the canting motion into place. The legs can be extended into 5 different height options. Its wider center hub delivers more stability and strength to support larger heavy rifles.
