Here it is sitting on my kitchen table. Brand new M14, just got it. And Sage stock right beside it. Any trick to take off muzzle break? Seemed like a simple thing except the thing will not budge. There was heat and some hammering to no avail. Am I missing something? Castle nut is slack of course. I do not see any silver solder - there must be some marks from solder if it was there but I cannot see any. Should I heat it up hotter?
