For a LRH capable bipod, I would feel completely comfortable with a swiveling, notched-leg Harris. Cant capability is a definite must. Cant angle must be limited to a reasonable amount, or else the rifle will have a tendency to flip over and hit the ground scope first -- I cringe every time that happens and with a Versa-Pod/Parker-Hale design it happens easily! Been there, done that.
I DON'T like pan on bipods. Once you reach the limit of the pan range, the bipod changes from a floating unit into a solid one. That, in my opinion, can have a harmful effect on recoil consistency from shot to shot. I'd rather have a stiff horizontal connection to the bipod so when I turn, the feet are actually dragged into a new position, constantly pointing to where the barrel is pointed.
I think Harris is a very good bipod and really I have no other complaints besides the slight tendency to hop. For LRH, I think it's beneficial to see your own impacts. Atlas is supposedly (I hear) a very good bipod also and it actually has some axial float, so it might be what I'm building is completely pointless -- but when you feel an unexplainable need to stand in a pile of chips, you come up with better mousetraps to build... At least that's my excuse...
I try to update the build log whenever there's real progress but I'm swamped with a million other projects to finish, not to mention I'm supposed to start a gunsmithing course soon. And that's on top of my day job in radiotherapy systems development...
There's some incoherent ranting about bipods in the blog which I'm not going to repeat here. Feel free to visit the blog.
