Re: TRS-1 mil/mil vs Grandslam 3-10 40mm mil/mil
Afraid you miss read the Nitrex site. Ignore their pictures of TR2 models which does not show a side focus. Yes, TR2 scopes with less magnification than the 3-15X42 does lack parallax adjustment....but the 3-15X42 and higher Tr2s have a side focus parallax adjustment. The TR1/Grand Slam models also have a parallax adjustment in models ABOVE power range of 3.5x10, but it is not the side focus type.
Natchez site does not mislead you. I have a TR2 3-15X42 and it is a side focus.
