There is info out there, but you have to dig around to find it. I've posted about Larue Harris + LT706 QD Swivel Mount "Combos" several times before but I'll answer your questions below. I bought a <span style="font-weight: bold"><span style="font-style: italic">"
Harris BRM-S + LT706 QD Swivel Mount Combo"</span></span>, and I've also bought just the LT706 Mount itself from Larue and installed them on existing Harris BRM-S (6-9" Notched Swivel) and LM-S (9-12" Notched Swivel) bipods.
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: ForceResponse</div><div class="ubbcode-body">Looking at a new mount for a Harris bipod on my Daniel Defense Literail. Anyone have a review of the Larue mount (706 LT QD) in action with the Harris swivel bipod? I'd like to know, particularly, what you may have experienced pro and con vs the American Machine or GG&G mounts. Thanks! </div></div>
It isn't a "review" per se', more of the nuts & bolts of the LT706 Mount. I do not own, nor have I used either the American Machine or GG & G mounts, but the LT706 is superior to the LT130 and any other mount that utilizes the bipod-to-stud interface. The LT706 Mount is superior to bipod-to-stud interfaces because it is a more direct, more solid mounting system that eliminates the bipod stud while also slightly lowering the overall height.
The LT706 Mount works great - very solid lockup and as stable as a Harris bipod is ever going to be. The LT706's tension adjustment is easily adjusted with the provided wrench. Once you have set the optimum tension, it will probably never need to be re-adjusted unless you switch the bipod to another gun that has a different spec rail. I also use some anti-seize on the engagement surfaces instead of oil.
Two cool things about the Larue "Combos" is that: (a) the "saddle"/"cradle" that the stock normally rides on is eliminated (lowering the center of gravity), and (b) the thumbscrew clamp that secures the bipod to the stud in the forearm is replaced with a QD picatinny mount.
There IS one thing that I hate about the LT706 Combos' as they come from Larue - the knob that adjusts the swivel pivot tension is huge, and theres' no room to grasp the knob to be able to turn it. Ridicolous. I use KMW Pod Locs anyway so not a problem for me, but be forwarned if you decide to by a Combo rather than purchasing the LT-706 Mounts bare. Below are some photos of an older Harris BRM-S + LT706 QD Swivel Mount "Combo" with the factory Larue Pivot Tension Knob on the rail of my LWRC M6A2-S and a Gen 1 KMW Pod Loc. You can see that the Pod Loc provides much better access for adjustment. Check-out my post below this post for photos of the newer style Harris BRM-S + LT706 QD Swivel Mount "Combo" attached to the ACCU-SHOT BT28 on the Anschutz Rail of my Tac Ops X-Ray 51. The newer LT706 Mount has a built-in Locking Tab.
In all fairness though, the ATLAS Bipods have a big pivot tension knob too - and it is mounted right in the crotch of the bipod and it is also a PITA to turn. That is one reason I didn't go with ATLAS'. A Harris equipped with a Pod Loc is much more easily adjusted when in position than an ATLAS is.
Below are some photos of a Harris BRM-S + LT706 QD Swivel Mount "Combo" I bought complete from Larue installed on my LWRC M6A2-S. I now use the newer version of the LT-706 Mount with a built-in Locking Tab (not that the Locking Tab was needed), but I wanted all of my picatinny mount bipods to match so I bought five LT706 mounts and sold my Harris BRM-S + LT706 QD Swivel Mount "Combo". I primarily mount Harris BRM-S + LT706 QD Swivel Mount "Combo" on the quad rail of my LWRC M6A2-S and on the ACCU_SHOT BT28 AFAR on my Tac Ops X-Ray 51, but I also have LT-706 + LM-S Combos' for both of them when I need a bit more elevation (where I shoot you are almost always shooting uphill, and the more distant targets require more front elevation).

And anyone who has used a PodLoc knows that they are MUCH faster to use than <span style="font-style: italic">any</span> knob. Pod Locs ROCK!
