Edgun r5m long shroud

What i mean by that is i have heard The recomended torque on the barrelnut is between 10-15 fot pounds(13,5-20 Newton meters) and since the day i got the rifle from Spain… the shroud have been touching the airtube.

The marks on the shroud too. So i tried to torque the barrelnut to see if i could fix the problem, but Even 3,5-4ft.lbs and the shroud is touching.

This got me also fnising issue nr2. To remove the airtube i have to bleed the tube from the front and screw it out, because it is not enough clearance just too loosen the wedge holding the tube. But thats a topic for another discussion!




 
Hi i have tried to use plastic shims between shroud and airtube while tightening the nut. 1.5mm shims. And using a level on the rail and two 5.5mm drillbits to level the shroud nut/cap. When i pull the shims out the barrel hits the airtube again. Never used more than 7ft.lbs on the nut. But i will try the cloth idea thanks David! 


as for the wedge Lou, if i follow the process to remove the airtube acording to manual and Eds YouTube videos the airtube is impossble to remove without. Unscrew it first. Even with the wedge completly loose the little lip on the airtube will not clear. Maybe the gun has been bent during shipping i dont know, bit it seems straight
