All in all, I am very pleased. I am now in the process of learning what peep sites to buy to replace the stock fiber-optics. I think this will be necessary to improve accuracy from 100 yards and beyond. The current front post pretty much fills up the target picture at 100 yards. 
Peep sights... the Williams varieties - I really prefer the FP sight to the WG sight. The WG is what I call a 'slide and glide' adjustment sight and the FP is more like a scope adjustment - 1/4 min clicks for an 1" @ 100 yards.
There is an issue with the FP... The peep cross-bar can be in the way of lifting the bolt IF the elevation of the sight is adjusted all the way down to zero yards.... Normally this will bever happen but it has been discussed when people are installing the FP for the first time. Once you raise the bar to the point that the gun is sighted in - then the problem is not longer a problem. Your current front sight will detirmine the heigth of the lift of the elevation bar.
This is a picture of the FP installed on a MK-85

If you look on the left side of the sight to the elevation graduations - you can see that I have lifted the elevation several marks to sight the rifle in, at this point the bolt, if it had a bolt, would no longer contact the cross-bar.
For the front sight i would suggest that you replace the Knight sight with a Williams ramp, fire sight, and I added the firsight hood to give the sight picture that you see a more scope like view.

This sight can be installed on a Weaver scope base and looks like it might work very well...

I think coyotewallce also has another variety mounted on his might - PM him and get the information from him...
Hope some of this helps...
