can anyone explain what the pros and cons are of haveing a front sight base on your upper? I'm all new to this and have been doing a lot of reading but just cant seem to understand why you would want or not want it.
If I got the Front sight base would I use a rear sight like the Magpul MBUS sight? Would you recommend anything else? There are just so many options I want to make sure that I do things correctly I am looking at these 2 uppers. I would like to put a red dot on my build. I have en route a spikes stripped lower and PSA LPK. Also can someone explain the difference between M4, Mid, Mid Light and Light with Front Sight Base: http://www.spikestactical.com/new/z/upper-556-16-mid-le-w9-bar-rail-fsp-p-682.html without Front Sight Base http://www.spikestactical.com/new/z/upper-556-16-m4-le-w9-bar-rail-p-661.html Thanks!

I'm all new to this and have been doing a lot of reading but just cant seem to understand why you would want or not want it. It's a like or no like part. I personally like the iconic A-frame FSB. There is a common misconception that they interfere with optics. They "disappear" and go out of focus (at 3x) as you dial up the power. There is a standard height and the "F" height. F height is .040" taller and meant to work with the A3-type flat top. Standard is for the A1/A2 with the integral carry handle.

You could use the Magpul, USGI carry handle, any number of flip ups or fixed rear sights. I'm not a MBUS fan (plastic)...I like the Troy. Weapon Revolution did a nice comparison of the popular irons. Also can someone explain the difference between M4, Mid, Mid Light and Light
M4 = The current US military carbine configuration. It describes the entire weapon system. Mid = Refers to a gas system length. It's a civilian configuration that is between carbine and rifle and usually sports a 9" handguard. Mid light = Mid gas system with a thin contour barrel Light = A thin barrel contour. Sometimes called "pencil" with Front Sight Base:

I don't like carbine gas on a 16" barrel. It's a personal preference thing. |

To me a red-dot is an optic and I doubt it disappears on a red dot. I don't use a RD sight but I believe that most of these are 1x (no magnification) so that it is a more natural sight picture when the user has both eyes open. I know that some shooters like irons in combination with the RD in the sight picture. This effect is called co-witness. |
