I ordered a Nightforce ATACR 4-16x42 FFP late yesterday and now begins the wait until it arrives. It was a decision between it and a very lightweight March 1-8x24 FFP, and I decided to opt for the higher power but heavier NF. Right now the top of my X barreled Impact .30 is empty. I'm hoping that the NF is as perfect a scope for the Impact as it appears to be.
