My first question would be: can you pop off the battery tubes or are they pinned in place?

I'm not talking about the rubber plug...I'm talking about the tubes themselves. When the ACS stock first came out, you could removed the end plate then pop off the battery tubes. Later, Magpul changed the design and pinned the tubes in place. I haven't held a STR to see if that is the case or not.

The tubes are riveted on the STR's. You have to drill them out to remove them if you want to pin underneath them,

thats correct the STR's tube are pinned... idk maybe ill just pin friction lever so that the stocks immovable......any other ideas besides return and get the VLTOR?

The magpul tubes have always been pinned, they just use rivets instead of a single roll pin on the STR due to the location of a threaded insert for the back cap. Just drill the rivets out(one per tube) and install short roll pins in the end when your done. You can then crossdrill and pin the stock through the detent rail and lock it solid so it doesn't wiggle(no need for epoxy if done correctly).
