Tom if you want to convert your's to a Flat top. I have a KA tactical stripped upper receiver you are welcome to. We would need to make sure yours dose not have larger pins . Some early AR were built to a different standard.
Another option would be a low cost upper. That would would not require any Gun tools direct swap out.

Make sure it is a Beretta and not a Taurus . Taurus makes a copy but is no where near the same value. Mag lock is slightly different. Right side of slide will say MOD.92FS-cal.9 Grips on the one in the picture I will send you are laser grips so ignore the CTC. This link may help you. If is a compact 92 value changes. Slide will not say 92 FS ,but 92 compact. http://www.beretta.com/en-us/92-compact/. and this onehttp://www.beretta.com/en-us/firearms/finder/?ds=Pistol#ds=Pistol&mpp=24 start with the second link.
What may seem minor can make a big difference in value.

Look at it make sure it is a 92 FS. The 92 FS is a 15 round weapon. There is only one size 92 FS. Give me a bit I will provide you clear ID for it.

Part two.
Contrary to what some say the 92 FS is an outstanding full size 9mm. It is easy to shoot and easy to become good with. The only difference in a 92FS and an M9 is the lower front part of the frame is straight on an M9 and a slight angle on a 92FS. I really like mine and so has everyone that has fired it.
Used hand guns condition rules. I will price local tomorrow just for reference. pretty sure the $60 range is right. If I were purchasing it from someone I knew and what them to feel better I would not have a problem putting another $20 or 30 on that. After all if your are not flipping it what the heck is $20 dollars on a darn good firearm.
If you buy it do not buy extra mags for it. Got you covered I have way to many. Good deal purchase I made few years back had a lot of them in it.

Assuming it is Not SS .
Trade in's range from $350 to just under $400. That would normally be the lowest unless it was one someone beat to heck. Setting a price on a used one like new is hard because with sales going on there have been some great deals on them. New $499 to mid $500. Of course some will always have the a lot higher but doubt they sell.
If a used one is really like new in the current market $460 would be a fair deal. You have to remember when you see $499 it is likely an online sale and there is shipping a FFL fees that bring it back up fast. With a person to person sale you have no shipping and maybe a back round check depending on your state.

Tom, that kit looks cheap to me, we can look at it some more latter. Spare parts kits come in all sizes. This one here is a bare minimum any Ar owner should have around
