I think I'm going to go for a TA11D. Height over bore should be about correct for the BDC, and I like the triangle. Extra eye relief won't hurt, either.
This was a really fascinating discussion, given my non-familiarity with BDC and height over bore issues, so thank you very much!
height of comb and height over bore/ barrel are totally different things. comb refers to the stock/ cheekweld while HOB is the distance between the scope and the barrel.
Comb has nothing to do with ballistics/ optics. HOB determines how acute of an angle a rifle barrel will have to be tilted up in relation to the optic's line of sight so that they may zero or intersect at a certain known distance. The higher the difference, the more acute that angle is going to be.
I'm a sucker for factory guns, or civi variants of modern military arms. Went for the updated factory 1.5 "donut of death" optic on my CQC. (Pic I've used before)
I talked to Pete today via email mail today. He has 10 of those scopes in transit. I have a eotech on 1 of mine Im planning on doing the swap on. Love the old ghost ring setup.
