Best Bipod for Choate Varmint Forend with Bipod "T"

[Plinkomatic]

So I have the Choate Varmint Forend with Bipod "T" rail on my Survivor .308.
I went and got a cheepie Bipod- a Shooters Ridge.  
Thing was total garbage.  Never was able to get it to lock down tight and it kept loosening.
It seems like someone must make a Bipod that slides directly into the T-Rail on the forend, right? Isn't that what it's designed for?  Or do all Bipods require the stud on the rail.  
I just want something really solid.  Don't much care about weight and don't want a swivel as it is only for bench use- I'm offhand when not on the bench.
Any help would be greatly appreciated.
Thanks.
Oh and as a note- my Survivor loves the South African .308 milsurp; almost as much as far more expensive ammo (Federal Match).   A little sticky on the extract sometimes, but suprisingly consistent ammo for .18 a round, about 1/5th the cost of stuff I use in matches.

I have the $60 Harris 9"-13" Bipod and a $40 Outers/Shooters Ridge clone of it, they both fit great on my .22-250 Fluted Ultra. The Shooter's Ridge is maybe a tad lighter constructed, but for all intents and purposes, works just as good as the Harris.

Hm...
Maybe I was using it wrong.
I tried and tried and the thing never tightened down properly.
Tomorrow I'm gonna call Harris (270.334.3633) and see what they say.

Same problem.
With the T adaptor, the mount didn't touch the forend.
