I'm thinking of buying my first high end bipod and I've been looking at this bipod. I'm undecided between this bipod and Accu-Tac HD-50. I want this bipod to used on both my air rifles and my powder burners. I'm leaning towards the WB-4 because of the quick detach feature but I do like the robust design of the HD-50. The heaviest gun I have is my .243 bull barrel which weighs about 12 lbs with scope and ammo
