I have used a bunch of bipods. Started with the Harris, moved to atlas v8, then evolution, atlas cal, 1st gen ckye, and now TBAC. I still have the Harris, atlas Cal, and tbac. Tbac is my current favorite.
I really like being able to just pull the legs into position just like a Harris, as well as being able to push a button and have the legs extend. The TBAC legs are under Constant Spring tension so no matter what height the legs are at when you push the button the legs keep pushing out unlike the Harris. The TBAC has better can’t tension control, easily swapped feet and leg extensions, and just a better overall build quality. I picked mine up used on here for around $400 with the clamp, spiked feet, and leg extensions.
The atlas Cal is nice and stable as well but I don’t like having to push the buttons to rotate the legs down instead of just pulling down like the Harris/tbac. I also really dislike the leg extension method, it’s like the air line disconnects, kinda slow and clunky to extend or retract the legs quickly. I really do like this bipod and still use it frequently but for PRS type matches on the clock I don’t like it. Every aspect of the TBAC is better but stability is equal for me.
My first gen ckye pod was difficult to lock out the panning, also didn’t seem to tighten down the can’t smoothly, was difficult for me to get the right tension. For me there was too many adjustments and felt kinda flimsy. I did like the way the legs extended, just grab a leg and pull down. Once again on the leg rotation you have to push a button. The ckye has a ton more adjustments so for a lot of people they like that, can pretty much adjust it for any situation but for me it was just too much. A few friends of mine have the newer ckye pods and they are a nice improvement over the one I had but I still prefer my TBAC and Cal.
And last but not least I still like my Harris, it’s stable, cheap, and durable. I don’t like the spring tension for folding the legs, and the fact the legs are only spring loaded for the first little bit on extension. If you need to extend in the middle of travel it’s clunky. I keep the Harris around to use in the few rifles I have left that I haven’t installed a small pic rail on the front.
Like asked above. What aspect of the Harris are you trying to improve? Each bipod has different features that it does well and others that it doesn’t.
RRS has a clamp that does both picatinny and arca so I have that clamp on my Atlas so I can run it on all my rifles as a backup and my TBAC has the area 419 arca clamp for my comp rifles.
