I want to put a SPARC on a new fun gun. I have LaRue QD on all my rifles, and I would like to continue the trend. I saw the review by Preacherman that the LT660HK was almost a perfect Co-witness, which is what I want. I would like to use the new LT751 for the reduced mass, weight, and improved FOV. The LT751 is 1.40" over the rail to gives an absolute Iron co-witness with a T-1, while the the LT660HK is 1.31" over the rail. So I guess to make a long story short, is the center of your optic the same height as a T-1 center? If so, I should be able to get the LT751, and get the co-witness I want.
Thanks |

Thanks The center of the SPARC is a little higher than the T-1. So that's why it needs the LT660HK to get the absolute co-witness. My guess is that with the LT751 you would have a lower 1/3 co-witness. -Sam |
