Who has used the Smith Enterprises gas block sight from site sponsor Nordic Marksman part number 440-2011-M305? The reason I ask is in the description it says it's used on the short barrel USN rifles 18". The actual height of it measured by Nordic as I was on the phone is 2mm higher than the one the short barrel non M305 threaded sights (SAE). It's the same height as the ones used for the 22" barrels, does it work fine with out major rear sight re-calibration or have you guys changed front sight heights?
