Got an Atlas the other day and immediately noticed how much easier I could load up the bipod, it seemed to "stick" better to everything and didn't slide forward as easily as the Harris.
Thought I would see if this was just my imagination, cuz I just shelled out about $300 for a BIPOD!!! Good grief!
Grabbed 2 guns that are almost identical, weighted the lighter one to match the heavier one to within an ounce. Put the legs on each bipod to the same length. I tested on 2 different surfaces, brown cardboard and thin carpet.
I leveled the guns and had the rear grip sliding on a piece of slick paper to minimize any influence other than the bipods.
Used my trigger pull gauge to slowly pull the guns forward one inch, did three pulls on each and averaged it all out.
Well, it wasn't my imagination, for the extra $200 you gain an average of 4 POUNDS more preload force. It also has more "give" and flex and is much more forgiving because the legs aren't as rigid when you push forward.
.........Cardboard.......Carpet
Harris....6.5 lbs........9.5 lbs
Atlas.....10.5 lbs.......12+ lbs (est 14)
(Trigger pull gauge only goes to 12 pounds)
I tried to isolate exactly where the difference was, the biggest thing was the foot material, it is much softer and cushier on the Atlas and "sticks" much better. I thought maybe the angle of the legs were a big part of this, but I actually shimmed the Harris back to the same angle as the Atlas and it actually REDUCED the preload force it would take by about a pound.
The feet on the Harris also roll much easier than the Atlas, but I locked the feet and it really didn't make much difference in the readings, just a few ounces.
Just some side by side comparison pics....
I guess you get what you pay for.
