I was sighting my AR down in my woods several days ago (using a Bushnell TSR-25), and when I got back I realized I forgot to put the caps back on the adjustment knobs. Luckily, I found one in my truck bed when I got back to the house, but the other one must have fallen out and I know looking for it in the woods is nothing but a waste of time. I contacted Bushnell and they directed me to the Parts Order Form page of their website. I was shocked to find it would cost me $8.50 (including shipping) to get a replacement windage cap.
On a side note, getting an elevation cap would cost a buck less; what's up with that? Aren't they the exact same part?
Anyway, I'm not sure if there's anything else that can be done in this situation, or if I need to just suck it up and buy a replacement. I know it's my own stupid fault, but I just can't seem to justify spending eight bucks for a little piece of plastic. This may be a stupid question, but is the cap really necessary? I would think without the cap, dirt could get in or it could be bumped and mess up the zero, which I suppose answers my own question.
