Have a sonic mod for the 6.5.
Only had rifle and mod for a week and although its been out every day, the last couple of days there has been rust residue on the barrels thread when i remove the mod at end of stalk.
I clean the thread right away and lightly oil. But every time i put the mod back on it squeeks on last couple of turns and leaves the rust on the barrel thread when i take it off.
Do you reckon i should strip the mod and grease the thread on inside of mod (its a overbarrel)?
