Spot on John,the problem with my Ar5s is definately power fluctuation associated with decreasing temps.
As a matter of interest I put my Ar4 over the chrono and starting off from a temp of 18 deg. C it registered an average of 774 fps.Left it out side ,temp dropped to minus 2 deg and recorded a average 770 fps. A lot better than the thirty odd I was getting on the Ar5s
