Sights? Accessory barrels

[ILHunter]

I am setting up a second Hunstman muzzleloader for a Co. elk hunt this fall.   I bought a 20 Tracker II as the platform and my kids will use it here for deer.
I sent my receiver in a little over two weeks ago for a stainless Huntsman barrel w/ Williams receiver sight and a .22 Hornet front sight.
It came two days ago (FAST) but it had standard sights and on invoice I was charged for the other sights I ordered.  (they probably just made an oversight)  
So I have my wife call NEF yesterday and explain the problem, they said they would ship them and I would have to figure out how to get them on.  My wife calls me at work, because she didn't like that answer.  I have her call back and ask if they screw on in existing holes, if so that is fine and if not I want them to do it.  She is told by NEF that they do not do custom work, I have to figure out how to attach them.

I think the Williams rear will go no with scope mount holes.  I am not sure if the Hornet sight will go on after their answer.
I was under the understanding that NEF had put these sights on for customerrs at their request at the factory.  ( I do not consider putting on some different sights of their own to be custom work.)

Here is my questions-
 Has anybody had NEF put on Williams rear and a Hornet front onto an accessory barrel?
 Do I need the Hornet front sight for proper point of aim/point of impact with the Williams rear?   (I would prefer the steel Hornet sight over the standard plastic front.)
 Has anyone installed a Hornet front themselves and how?
 Has anyone had a gunsmith install a Hornet front sight and how did they do it?

Any help, ideas and experience are welcome.
Thanks ILHunter

Bump
Anyone?  Should I post this question in the rifle forum?

I received the sights that I originally ordered with the barrel in the mail today.  The receiver sights lines up fine (which I thought it should).

Correction to my first post:  The sights that came on the barrel are Williams aluminum rear and front, not plastic.

Now the .22 Hornet sight actually appears to be slightly shorter than the front that came with it.  I do like the square post of the Hornet sight better than the thin blade with round top that it has.  It appears that the front is held on by one screw.  The Hornet sight I ordered ony has one screw.  The bottom of the sight base is contoured to the barrel, but I still would think it could come loose and spin with only one screw to attach it.

I think that I am going to install the Williams peep sight and then shoot it with the original front sight to see how it shoots/ how I like the sight picture.  I am hoping it will shoot 405grain Powerbelts over 100 grains loose 777 good enough for minute of elk vitals to 125 yards.

Update
I have installed the Williams aperature sight, which is simple.
I removed the front sight and then compared the .22Hornet sight to it and screws.  I was surprised that these front sights are only attached by one screw, I guess the contour fit with the barrel keep it from rotating on the one screw.
The .22 hornet sight had a smaller screw hole and a smaller screw.  The only idea I had was to drill out the hole larger in the Hornet sight and use the screw that came with the standard front sight.
I'll pobably do some shooting first to see if I will even bother.
I was rejected for Co. elk permit so I am not in a hurry, I just need it by Nov. IL season.

Howdy,ILHunter a drop of med. strength{blue} locktight on the sight screw will keep it from shooting loose and you will still be able to remove the screw if you want to change the sight. :money:

O.B.D.
Great minds think alike!  I did use locktite when I put it back on.
I need to start shooting as soon as it cools off alittle.
