Im going to build a rifle dedicated for my thermal night rig, I have been using a std rem 700 the last few years, but wanting to try a 60deg throw to work a little easier with my Haloxrf, so I picked up a new Zeus. Has anybody had any issues running a Zeus in sub zero temps all night long? I know the design is a little different than a rem700 clone with a few more moving parts, so just want to see if there has been any problems. Thanks
