Ok, now you guys can beat me up. I finally got the parts with the holiday sales for another build. A budget build.
I also needed another optic so I got a Swampfox (covers head) Arrowhead 1-8, put it on my Aero build and put the Bushnell on the new one. Hopefully tomorrow I'll get them both sighted in.
All that aside for a second, I haven't been able to find a definitive answer to this question:
What is this on the bottom of these LPVOs?

My guess is that it has something to do with sealing up the internal environment of the piece, but I have certainly guessed wrong before.
Thanks.
