Ok, guys, here it is. It finally came and I put it on. I have a few suggestions to start off.
1. Don't drink before you attempt to do this. At least not much, maybe one beer to ease your nerves because you may need it.
2. Make sure you do have something to drink afterward.
3. Take your time
Anyway, putting the wrap on the foregrip wasn't too bad because it's fairly blocky. On the other hand, the stock was a pain in the ass. It was very difficult to get it to contour to all of the slopes and "roundness". All in all, it came out about the best I think it could have. I'm not sure how long either ill leave it on, or it'll stay on itself.
I definitely do suggest following the instructions to the T.
I'll follow this up at some point with more pros and cons. (eg waterproof ness, how it stands up to heat)
