Ok so Ive got my lower all ready to go. Im just about set to order my upper kit with everything else I need and then I start wondering about a few things. I want a flattop to be able to use the gun if/when I go hunting with a scope (say 3-9 or 4-12 power range). The thing that sticks out to me is the FSB being in the way. I have read in a few places that even though it is there you dont notice it with anything basically 3 power or greater and at most it is a slight shadow at the bottom of the view. I was hoping someone could explain this to me or explain what needs to be done to use a scope. When I look at the pictures in here everyone with a scope either has a flip up front sight in the down position or not front sight at all. I have read a little but most posts on the subject dont explain it and just tell you to not worry about it. I want to use iron sights for the most part and the scope for the occasional shooting. I would rather not mount it high up on top of a carry handle. I would like to use a flip down front sight but this gun is starting to run more and more over budget and as such if I can get away without spending the extra money I would keep it the basic fsb. |
There's not much to explain. Grab any magnified optic (scope, binoculars, camera with a telephoto lens, etc.) and adjust the focus so that objects 100 meters or more are in perfect focus and then hold one hand out at arms length with one finger sticking in the way of the view. You'll see that with the focus adjusted so far away that anything close is too far out of focus to see, and the effect becomes greater the higher the magnification. |

benzy2, fear not. Keep your front sight. If you have a scope with muti-X magnification your front sight will NOT interfere with your ability to see a clear image of your target. It will not affect accuracy. Up around 10X, you cannot see even the faintest shadow of your front sight - it's just gone. The explanation is highly technical and will not really satisfy your "gut instinct". What you need to use a scope is a good sight base and good rings. The scope has to be mounted relatively far forward to give you the eye relief most scopes require, especially when you shoot from the prone position. This usually requires an extended rail. Mine is an ARMS #36-SEX (Super EXtended). I have Leupold MkIV rings. |

When you look through a scope the visible light you see (the image) is hitting the objective lens and is being concentrated and focused onto the exit pupil in a very tiny spot. The exit pupil then expands and focuses the light into your eyeball. Now if you put an object very close the the light gathering objective lens it becomes invisible because the object is so close that when the objective lens concentrates the light from the object it is focused too short of the exit pupil. Its easier to think of the front sight as a rock in a river as the water flows right around it. You do not need a flip down front sight to use your scope. I had my scope mounted to the top rail with short rings for a long time with no problems. If you wanted to use your irons and the occasional scope I would recommend the carry handle. Its way cheaper and easier to remove/attach the scope without having to re sight the damned thing and all it takes is one easy nut to screw on/off. The only issue I have run into with using the carry handle verses just mounting to the top rail was that there is a significant angle of error when using the scope -50yds, but anything that close you can easily hit accurately on the fly with the irons. I guess the only isse you have is aesthetics vs. money vs. practicality. http://i4.photobucket.com/albums/y105/evergloww/Scope.jpg |
