The windows are adjustable ALL THE WAY around the blind. There are 4 slide buckles positioned on the corners and this is how you open and close the blind. If you want, I'll shoot some photos and email them to you. Anyway, if a turkey were to slip in behind, there are also 4 shooting ports like the one on your BS5. You could close the slide window behind you, drop one or 2 of the windows and shoot out of those. You could even, I believe, close the window behind and drop the slide window instead of the shooting ports. You would have to do this slowly, but I am pretty sure you could get away w/ it. I've hunted out of other blinds, and NOTHING comes close to the Matrix. Visibility is simply unmatched.

I close 3 slide buckles and leave one open. That alone gives me 180 degrees I can see and shoot from. The thing is awesome. And yes, it has netting all the way around it. For turkeys, I leave the net up. They don't care. Check one out at www.doublebullarchery.com If you request a catalog, I believe they send you a video as well. It's awesome. IMHO, there is no better blind on the market. I love mine.
