Hi all, I picked up a Christensen 308 AR upper and it has an integral 20 moa rail. I dont shoot at and suck at long range shooting.
Will the 20 moa rail put my scope adjustments too near the end of travel ?
Should I put the barrel into my existing 308 AR upper? It has a special barrel nut I dont have the wrench for but I am sure I can work around that.
The other issue is the C A upper does not fit my existing 308 AR lower.
