That TBAC one looks quite interesting, shame its a bit of a lump and relatively short legs.
I go round and round on bipods, but keep going back to Harris 9-13. I like the ease of both opening and extending the legs. I don't like the fact it digs into my back though.
I've also got a Tier One, and I like that I can mount it on a picatinny and can have my sling attached to the pic rather than the bipod so it doesn't dig in. However, there is too much play in the legs (and the adjustment is extremely sensitive), and the leg extension/contraction isn't that smooth on one of the legs.
For me, the ideal would be something with harris style legs, with a low profile / out in front picatinny style mount that sits in front of the sling swivel.
To be honest on my hill rifle I'd happily permanently fix the bipod.
The Backlanz Notched (
BACKLANZ
Carbon Bipod - Notched) looks pretty perfect for what I want out of a bipod, but no chance I'm paying £500 for a bipod.
I get the Javelin idea, perfect if you only occasionally shoot of a bipod, but alot of my stalking is on the hill, and almost all of my shots are prone and off a bipod. If Spartan can come up with a Harris/Atlas (i.e. fixed to the rifle, fold out legs) then I think they'd sell well. The Valhalla is on the right lines, but a bit OTT. From
@nun_hunter 's post above, it sounds like something may be in the offing.
