Thunderbeast or CAL

I have both and I like both of them. My only gripe about the TBAC is the spring loaded legs. They're quick and easy to extend, but putting them back in isn't nearly as fast and easy as the CAL.

I owned both as well. Still own the Atlas Cal. I also have the MDT Ckye pod double pull. The MDT is gaining some ground in my favorites category but only used for the last year

The TBAC is like a Harris in its design with the legs. Made me feel like a polished Harris when I used it

I prefer the grip and rip collar on the Atlas legs

I use mine primarily in fields. Corn/beans/alfalfa etc. The TBAC like the Harris has the inner portion of the leg extend. So if you use in dirt or mud you need to be cautious of sucking the dirt up inside the leg when you collapse it. It tends to collect dirt and get gritty even if you’re cautious

The atlas and ckye pod it’s the outer portion of the leg that extends. So the leg notches are up by the forend and not in the mud

The TBAC again like the Harris allows you to grab the leg when collapsed and rip it down. Where the atlas has a button to push to drop the leg. This is when initially folding the legs perpendicular to the rifle

I run hawk hill talons on mine. But if I remember correctly the feet rotate on the TBAC like the Harris does as well. The cal model of atlas legs don’t rotate

I had an Early TBAC. I sold it and bought a CAL. I just never liked it. I probably put a few thousand rounds on it before giving up. All of the fasteners worked loose and had to be locktited, and it would roll away shooting down hill on hard surfaces.

Ive owned them all. The only ones I still have are Harris and Cyke Pods. If it wasnt for PRS, I would only have Harris.

This is exactly where I ended up.

I also really like the accu-tac, but haven't justified buying one because it does nothing better than the ckye pod or Harris that I already own.
If I was to go buy one today with nothing else to compare to I'd likely get an accu-tac and end there.

The TBAC is the best with fit and finish, and is a really nice, well built bipod.
I prefer the atlas partly because it suits me a little better for field conditions and it’s also bit less expensive.

Great feedback. Much appreciated.

The TBAC is similar to the Harris. Like a Chevy impala vs a Chevy Camaro

I still own probably 4-5 Harris. All swivel stud mounts. Haven’t used one in probably 5 years
 
It's not that simple. The TBAC and the Harris have 2 similar features.

-the spring loaded legs
-deploying them without having to push a button

Other than that, the TBAC is far superior. It has those two features of the harris, but the rest it shares with the Atlas. Harris is made from stamped metal, and hops around on lighter or higher recoiling rifles.

The TBAC has a little more play than the Atlas, so it sits back down on target instead of hopping if you're on a hard surface.

If you're shooting a heavy PRS rifle or something with little recoil, this really isn't an issue with any of these bipods.

Similar in the way it deploys/extends and how its extensions on the legs have the notches to the dirt is what I’m referring to

For some of the reasons stated above.

I like the Tbac for range/prs use
I like the tall cal for field use

I’m not a huge ckye pod fan but I could get along with them if needed.
 
The question is, which of the many available options out there, is that 4 runner to YOU.

I tell my customers, to ask questions, get advice, but in the end it is yours. Get the thing that will make YOU most happy. You're the one who has to spend the money and live with it.(and in some cases, justify it to the wife.)

No matter what your choice I hope you will let us know which way you go and your reasoning…..

Happy New Year
Thanks, @Holliday. I ended up going with a CAL. After reading everyone’s reviews I noticed that very few people were unhappy with the CAL. They were a good amount of recommendations saying the MDT was “the best” but not compared to the what you get for your money.

The key difference between the Harris and the TBAC is that the Harris holds the legs rigid in place once folded downward. No fore and aft play.

The TBAC has what I consider a generous (but perfect amount in my opinion) amount of play fore and aft. With the very least amount of traction, an ever so slight push forward gives you a fair amount of recoil room.

The latter is very important to me. A deal-breaker if you will. Other bipods like the atlas have this play as well.

Pro shooters like @Rob01 like the have told me they like Harris and don’t see the “non-fore/aft play” as necessary. Perhaps he’ll chime in.

Other differences with the TBAC is the pod tilt lock is the best I have used. My old Harris did not have an arm, so I set it with loctite/ pliers and that worked fine. I hated this on my atlas. The wheel lock never seemed to hold over time.

The TBAC also has a definitively different stance at the top than the harris and juts forward from the mount. Both of which I prefer. I also prefer the QD mount but I believe harris has that as an option now. Finally I like the claw feet design of the TBAC better than any of the others I have experienced but that’s personal preference.

As has been mentioned, the fit and finish on the TBAC makes it just a beautiful but rugged addition to your rifle. Perhaps aesthetics shouldn’t be at the top of the list but if it’s there, you certainly can appreciate that it’s an added benefit.

There is no such thing as a "pro" PRS shooter, FYI. It's a hobby.

That said, TBAC is obviously a much higher quality bipod than a Harris. Whether that quality is needed or worth it to any one individual is subjective to any individuals needs and wants.

You've supplied a nice in-depth look at the TBAC. I don't own one, but if I was to buy a bipod today, it would very likely be a TBAC.

Thanks for the clarification. Sloppy of me.

In the vernacular “Pro” is used to describe both someone who a paid professional or sometimes by us peasants as a term of veneration for someone with a substantial expertise and knowledge. I usually just say “Gamer” ………

Again thanks

No need to thank me, it's just a pet peeve of mine.

I just hate when the designation of "pro" gets used to elevate what are essentially hobbyist shooters. As if their opinion means more than anyone else's in this hobby. It doesn't.

Conspicuously absent is your opinion on the Harris and the hop issue.

Some say it is just bad form.

I say it is hard to always have perfect form, especially when hunting. Slop allows for this and give a wider margin for error. My opinion.

I purchased the Gunwerks bipod Gen2 for hunting. When I received it everything was very nice, except there was almost no fore and aft slop.

To make matters worse the right leg had noticeably less slop than the left leg. Below are groups fired with the TBAC and the Gunwerks. Not my best shooting but as I predicted the Gunwerks opened up the groups and threw shots left.

I contacted Gunwerks with these results and they could not have been more helpful!

They help me rework the bipod to have the slop that I wanted, as well as both legs having the same slop. They went far in above and beyond for me. I could not have been happier with their CS.

I finally got out and shot groups with the reworked Gunwerks the other day and suffice to say the groups closed up nicely. Sorry I don’t have those targets to show you.

Now I’m sure one could look at these targets and say there’s something wrong with what I’m doing. I’m willing to admit that, my whole point is that slop gives you an extra variable when in the field to help idiot-proof of your shot. Above all else you want both legs functioning the same in terms of slop.

PS: I was adjust my zero between groups hence the moving group center point on the TBAC from 1st to 4th. I like to zero .1 mil left, to account for spin drift when hunting.

Personally I prefer bipods in which you can take up slack for recoil management, especially in compromised positions.

Obviously Harris doesn't have that ability, and the bipod can certainly hop if your fundamentals aren't perfect. The lack of this feature isn't always necessary on a lot of PRS targets, but it can hamper precision.

I've also seen a few Harris' break in PRS competitions. They certainly aren't very sturdy.

Between those two, no vote, either have too much play for me.

I waited a long time to finally get a hold of a TBAC, as I had the impression that it was just a better-made Harris, and I was bummed to find out that they have so much play in them and I hate it (and feel the same about the play in the Atlas bipods and Ckye-pods), and I ended up selling it almost immediately.

I don't get to shoot as many matches per year as some others do around here, but I shoot more than a few, and over the last few years there have only been ~3 times when I came across a stage that required a fancy Ckye-pod (and so far, 100% of the time there's been a cool MF'er in my squad who's loaned me one for the ~90 seconds or so I needed one).

I still prefer the good old cheap Harris BRMS... albeit with added KMW Pod-Loc, Hawk Hill Talons (that I run with JKL covers on 98% of the time), and RRS ARCA/pic adapter, which all ends up making the Harris not so cheap anymore.

I suppose an Accu-Tac would be an upgrade to the Harris with its wider/better geometry and feet that don't roll, but I've never felt like the Harris has ever held me back enough to bother getting one just yet... (maybe someday?)
