The Atlas Bipod is the best competition bipod on the market today. It’s lightweight design and infinitely adjustable legs make it the go-to support for precision rifle shooters.
However there is one drawback for competitive shooters: the dreaded tension knob.
The Atlas tension knob was designed to adjust with your fingers to allow a smooth pan and tilt, and it works... for the first few shots, then it tends to loosen up.
Now we have a solution... the Atlas Tension Wrench.
The ATW allows you to put the exact amount of friction you want on your tension knob and it won’t come loose. Guaranteed.
