Hi all, maybe a newbie question but I am trying to fit a NUPROL BOCCA Series Three AEG Rail 7'' to my Bolt B4M1
I says its a drop in rail with all required fittings and fits using the standard delta ring.
It comes with 5 screws and 5 grub screws.
The screws obviously join the 2 halves together, however I have no idea where to use the grub screws as there are no threaded holes the will go into.
the delta ring itself does not hold it in totally securely, so it has a slight wobble....
Any suggestion or help gladly taken, even if the suggestion is to bin it π€£π€£
Cheers
Paul
