Help with 16” SLR Handguard on Aero AR10

[DRAM40A1]

I installed this SLR 16” Solo rail per the specs, which is 35 inch pounds. It moves forward during recoil. I went to 40, then 50, and yesterday I used a seekong 65 inch pound torque wrench. Not sure how much more it can handle before snapping the 8x32 screws but three rounds through it and it’s still moving forward. Any ideas to keep it in place?
I bought it used for $130 shipped. Seemed like a deal at the time but I’m not so sure now!

No way it can move if installed properly. Used many of these. Are the wedges installed properly??? That's way too much torque on those bolts by the way. Hopefully they arent seized...

Well, I don’t feel like a total dumb ass because I did pay someone $40 to put this one together. I should have spent the money on the tools for the large frame receiver. I have the tools to do AR 15s but not the large frame.
I pulled it apart, it wasn’t seized luckily, and reinstalled with the wedges properly seated in the groove in the barrel nut.
Thank you padom for the reassurance.

Yep those little wedges only go in one way and they arent the same size. Glad you got it square away..now go ask for your $40 back. Lolol

No doubt, I’ve been messing with this thing for 4 or 5 days. Loosening, tightening, pushing, pulling!
It just took a little nudge to actually take it apart for a look see. Thank you again.

What do you prefer for receiver block to work on AR 10’s?
I use a reaction rod for the AR 15s.

Geissele reaction rods for both AR15 and AR10...could have got them cheap last week with their 30% sale.
