All the fuss over a scope.
not quite, the horizontal lines would more likely be for range finding since they arn't attached to the zero'[R-DEV wrote:Masaq;1099696']http://www.trijicon.com/pdfs/ACOG_Specs.pdf
Shows you the various sight options (it's the sales brochure from Trijicon) - many many versions of the sight available, and a whole bunch of them have the horizontal marks, including some variants of the RCO. (RCO just means it's the model (4x32) adopted by the USMC and Army.
The vertical marks are adjusted for range - allowing you to zero the weapon and then adjust fire for ranges easily. I'm not 100% certain, but I'd assume that the horizontal marks are a similar setup to adjust for windage. Guess only.
Well the central reticle can be used for rangefinding. The base of the chevron is the same width as a 19" target (approximately a man's shoulder width) when viewed at a range of 300m. The horizontal lines further down correspond to the width of a man at the range the sight is calibrated to (Source: GunTalkTV - The #1 Online Resource for Gun Training @ 3:00+).Bringerof_D wrote:not quite, the horizontal lines would more likely be for range finding since they arn't attached to the zero
As far as I can see, there's no size difference between the innermost ticks on the horizontal line and the outermost ticks - and I'd imagine you'd need some kind of different sizing - like there is on the vertical axis - to actually rangefind. Like the SVD has a curved scale on the left hand side, for example.Bringerof_D wrote:not quite, the horizontal lines would more likely be for range finding since they arn't attached to the zero
