I own & use both Atlas and Harris bipods, but usually choose an Atlas over Harris for the reasons below.
- The Atlas has the ability to PAN, which the Harris lacks.
- The Atlas can be stowed either with the legs forward or rearward.
- A shooter can preload an Atlas bipod easier and better then a Harris.
- Atlas can be deployed silently, where the springs in the Harris can cause noise.
- Pulling a rifle towards you to re-position it can cause the legs of a Harris to collapse, where the Atlas will not.
- The Atlas offers more deployed positions then the Harris. The Harris is either up (stowed) or down (deployed), with no other options.
- A user can add sections to modify the length of the legs along with the type of feet (rubber, spike, etc) with the Atlas at will. Doing so with the Harris is a permanent change & only the type of feet can be changed.
Plus... I've actually managed to BREAK one of my Harris bipods. All of my Atlas setups are still going strong.
