If you have an AR-15 A3 with front sights and you mount a red dot scope to the rails on the reciever woudn't the sights be in the way? Explain that please. I have seen service rifles with this setup and can't believe it would be very useful. What is the best way to mount say a Trijicon ACOG to an AR-15?
Intelligent answers only.
No, the sights are not in the way. Your focus is on the target and not the sights so you don't even see them when shooting.
When using a red-dot scope you keep both eyes open and the dot appears to project onto the target. Once you get used to shooting with a red-dot you can get very fast at acquiring and eliminating targets, especially in CQB (Close Quarters Battle) and/or low light situations which is what they are primarily designed & used for.
A BUIS (Back-Up Iron Sight) should be used in conjunction with a red-dot scope as they fold/pivot out of the way to eliminate any possibility of obscuring the dot from the user. If for some reason the scope fails or you just feel the urge to use iron sights then the BUIS can be brought up and it will automatically align/co-witness (after it is properly zeroed) with the fixed front site through the scope.
Now on to the second part of the question. The ACOG is a fine scope and I would highly recommend using a quick-release camming style mount and avoid the screw type. In my experience the screw type will eventually shoot itself loose unless it is constantly checked (that is why you see para-cord wrapped around the accessories on our troops weapons).
A.R.M.S., GG&G, and LaRue are the best of the several companies offering quick-release style mounts for the ACOG, stick with one of them and you won't go wrong. Personally I would recommend the A.R.M.S. mount because there is a feature that allows the camming arms to be zip-tied in place for additional protection from accidental release, you definitely don't want your ACOG hitting the ground.
