If any one was wondering why this mount would not fit the NEW Sytle telestock 6 position (fixed or adjustable), well It was made to fit the original 4position style telestocks. The older style does not have the reinforement ribs where the new style does and that is why the mount technically does not work with the new style stocks.
Well if you really want to use one like I did, Get the dremel out and remove the portion that is in the way. What little amount of the rib you remove will not cause any weekness. If it did I did not notice any. That stock is really stiff to begin with and when you attach the mount it should add any strength back that was lost when removing the portion of the ribs on both sides, if anyone is worried about that.
Anyway the main reason I wanted to use this was the ease of removal of the sling when not needed and it actually brought the rifle in closer to the body and keeps it out of your way, Something else that I was looking for in a sling/mount combo also.
If you notice in the picture I also have a KAC receiver sling mount also (both made for the QD swivel) and If I used that mount the rifle is really far away from the body in the barrel down resting position and tends to interfere with other functions your performing, like using the hangun, etc...
Oh, the sling I am using is CQB SOP Sling #137
Hope this helps.
