RIS wobble

Hello all, 

 

Nuprol delta sopmod. I’ve got some wobble on the RIS rail. I’ve tried duct and electrical tape. 
 

I’ve also searched for hidden secret screws to fix it and I’ve had no luck. 
 

Does anyone know of a way to get a solid permanent fix? I’m tempted to hit B&Q for some bolts to torque it down to the outer barrel. 
 

Any and all suggestions welcome. 
 

Thanks in advance, 

 

Ron

Are you sure it's the ris rail and not a wobble between upper and lower receiver? I've had similar wobble that turned out to be receiver wobble. Some ris rails also have a tightening lever thing that allows you to tighten them to the delta ring. If there's a screw on the top of the rails that can tighten this lever. (picture from an lct ris rail with this lever) 

 

But all that aside if there's a wobble then there's space somewhere and you need to find it and remove it. Best of luck!

Are you missing the fake gas tube? The silver wire/tube that goes from the front sight to the upper receiver. The ris rail should almost grip this and that would stop the rotation potentially.

If you're still hunting for the grub screw, I tend to use Accu for random fixings I need. Here's a link to their grub screw page.
