Picked one up today. One of those things you don't quite need, but I was compelled to own. I tweaked mine with a pic rail, and a inexpensive Tru Glow Micro Tac Laser on top. Wrapped the "Beak" in some cushy baseball bat wrap which worked out rather well. Have the Opsol adapter on order, but the mini shells were nowhere to be found today. Not the sort of thing I would take to my local rifle club, so I will need to wait for an invite to some of my buddies private ranges to give it a proper run.
