for stability the Super Cal and Accu-Tac are money well spent
I would agree with this. I'm putting together a video comparing the Atlas CAL, Super CAL, Accu-Tac 50, Elite Iron and a Phoenix for ELR work. Still a ways off as I have to figure out the right way to demonstrate everything on video, but here is the summary (all with ski feet):
Phoenix:
- Hands down the winner for stability and play (there is no play whatsoever) and getting shots on target - like, no comparison.
- Hands down the loser for ergonomics, transportability, and set up - like, no comparison.
- Winner for fine adjustments (getting bipod exactly where you want it to be).
- Winner for width
- Loser for making quick adjustments.
- Loser for looks (this thing is ugly).
- Phoenix, both Atlas and Accu-Tac are all tied for multi-rifle use.
- This bipod is very much two sides of a bipod coin - A #1 in some things, shit in others (though A #1 in all things related to the actual shot)
Elite Iron
- Worst for stability and play with legs extended, and call it a tie, but essentially the lowest even with legs retracted. The nature of the pinnacle of the legs being above the barrel helps this quite a bit, but there is a lot of play in the legs.
- Worst for multi-rifle use - you may need additional parts that, while not hard to change out, aren't the easiest or quickest either.
- Coolest looking
- Third for fine adjustments at 5/8" between leg detents.
- Call it second from last for making quick adjustments - adjustment mechanism is a little unwieldy
- I got the Elite Iron with high hopes, and I have to say I'm a little disappointed.
- Most expensive of the bunch.
Accu-Tac 50 HD
- Very limited play with legs retracted, while some with them extended. Both of the Atlas bipods and the Accu-Tac are essentially tied here - maybe slightly less play in the Atlas pods.
- I like the spring quick retract.
- Second only to the Phoenix (which has infinite) for fine adjustments at 3/8" per detent.
- Very cool looking (but not as cool as the Elite Iron).
- Second to the Super CAL on width at the mount, and third at legs (behind Phoenix and Super CAL).
- Pretty ergonomic to use, but barely #2 behind both Atlas pods
Atlas Super CAL
- Very limited play with legs retracted, while some with them extended. Both of the Atlas bipods and the Accu-Tac are essentially tied here - maybe slightly less play in the Atlas pods.
- I like the mechanism the best for extending the legs (Accu-Tac wins on retraction mechanism).
- Widest mount and feet outside of the Phoenix
- Barely worst at fine adjustments at ~11/16" - 3/4" - this is my only complaint with the Atlas pods. Would be very easy for them to make one with lower distances between the detents, and if I'm not using a rifle with an ABR, this comes into play more than I would like.
- Very easy to rotate legs - I think it and the CAL are the easiest of the bunch in this regard.
Atlas CAL
- Not really fair to compare it to the others in the list, as it is a different class.
- Most ergonomic of the bunch because it's the smallest. Very similar to using the Super CAL, but since it's smaller, it's slightly easier to handle.
- Tied for last with the Super CAL at 3/4" for fine adjustments.
- Best by far for portability.
- For everything else, see Super CAL
TLDR:
If I could only have one bipod out of the bunch, it would be either the Super CAL or the Accu-Tac. Both are very beefy and stable, yet surprisingly versatile at the same time. They both have slight pluses and minuses over the other, but essentially equal out.
If I had to sell one, it would be the Elite Iron (and I still may).
The best at helping get rounds on target is the Phoenix (by far), but you need a frikkin' trailer to cart the thing around. So unwieldy... I just hate taking it out and getting it set up.
I am still searching for the perfect ELR bipod. If the Elite Iron or Accu-Tac had thumb screws or clamps to lock the legs in place once set, I'd be sold, as that would take all the play out. Alas, in a world of PRS where everyone uses regular or spiked feet and loads their bipod, manufacturers don't value such things. Until they do, I'm either stuck using a very unwieldy Phoenix to get the best consistency, or I'm shooting gimped for the sake of usability.
