After going back and forth about selling the SP-1 I have.. I'm back on the keeping it side of the fence..
With that, the upper that was on the gun is not original, and has a shot out barrel. So.. It's time to make this shooter rifle, shoot, and shoot well
I have a brand new fire control group, and the receiver is in great shape. I also have a adams arms piston system that was on the gun and in good shape. I have a Lance direct thread can that I'm going to run too.
So the question is what kind of steps should be taken to help with barrel climb, balance and reliablity?
