I've taken this thing apart looking for some Lil nubs like the Tupper ware stock on the 700, but I don't see them. I've also searched the Web and can't find any pics of the "speed bumps". The only thing I see is the side of the barrel channel hits about 2" in front of lug. I was gonna relieve the channel some because a dollar won't slide. So if one of you fine gentleman can point out where the bumps are, I would really appreciate it.
