Just got my barrel from them today. Screwed off the 223 barrel on my model 12 to put on my new 6.5 tcu barrel
. Well the barrel nut will olny screw on about half way and also the action will screw up about an 1/2 inch and gets stuck. It seems to be the threads on the new barrel. Any one else ever had this problem. Do you think they will fix this.
