How would you convert the front post on an A2-style upper to an aperature sight?

I'm thinking about dedicating my WOA service rifle upper to paper target shooting, and I have this idea that putting a front aperature on it would make it slightly more accurate (than the front post on it now). I know the aperature won't make the gun more accurate, but I think you get what I mean -- it will make it easier to sight the gun more precisely on paper bulls-eyes because the right size aperature will create a thin line of white around the bull, etc...

So what is involved in putting a front aperature on an upper like this?



Do you need to replace the entire front sight block with a low profile one? Who makes the parts to do something like that?

Better yet, does any vendor make a replacement front post that has an aperature on top of it? (that would make things really easy, and also interchangable)

Thanks.

There's at least one manufacturer that makes a front aperature that screws right into the front sight because I have one in my gun room somewhere that I bought a couple of years ago. The disadvantage with it is that you lose 1/2 of the adjustment of the front sight because it can only be used front and back, unlike the post which can be used on all four sides. You may find out that your sight picture doesn't line up with the target at specific ranges as a one position will be too low and a 180 degree turn of the front sight is too high.
It would be better to cut the front sight off and install a match front sight on the end of the barrel. (You wil need the muzzle of the barrel cut down to a specific diameter to fit the front sight base).

Several different versions too as far as line widths and with or without a center dot.

I vote for a bloop tube and a globe sight:



I just like the model less juiced.

Oh my goodness, you would hafta be muscled up like that from just to aim that rifle.

I've never used a globe front site, but for an AR, a skinny target post makes a world of difference. Even better, I like the ones that are machined on a taper up to almost a point.
