We haven't noticed any zero change but we haven't done any precision work with it either.
Alright, got the rail installed (after 1st Army finished T.I. it) haven't shot with it yet, won't until I get in country in a few weeks, but here is a pic of the gun pretty much all set up. sorry about the kind of dark, blurry cell phone pic.
