I just bought 4 barrels and 4 DCI receivers. I have tried every barrel on every receiver and each will tighten to about the 9-10 oclock postion. I am unable to get any of them to the 12 oclock postion.
If I back them each off I get a nice gap between the receiver and barrel face. Any ideas how I can get these mounted correctly??
There must be a solution. If I use a big washer then I have a large gap in my breech.
I need advise on this one.
