Okie made some good points. Choose the best scope that you can afford. Military surplus is probably the place to start looking for camo.

The best optics is subjective. I have used $20 binos up to a $1000 pair of Swarovski SLC.
Looking at value for the money I would go with Steiner, Nikon or Leupold, but there are certainly other choices that would be as good.

For production knives most name brands will work. Lately I lean towards Buck and Cold Steel.

The tacti cool spec ops stuff can be a little over rated. (I was an MP with the Marine Corps) Refer back to basic military surplus. Keep it simple and keep your gear organized.

Shooting gloves, you will have to experiment and find what works for you.

Radio set-up would be what ever you are willing to spend.
