I haven't seen one installed but don't think it looks very sturdy. In theory it's a good thought, but once you see it, those "sights" are going to be all over the place, granted it is GR's meant for short range, but it's just not how good gun accessories should be. A GR setup is more than a hundered bucks, this thing includes them on a mostly aesthetic part. Maybe you'll find them better than a little bead. But think how cheap this is compared to a real setup, there is a reason for that. It just seems like something that hillbillys would put on their Maverick to make it look tough. And at that price is probably all it was meant for. Like i said I have not used one but guarantee it is garbage, and the last thing I am is a gun snob.
Dfariswheel took the words from my mouth with his last sentence.
You can find a good used barrel with rifle sights for not that much money. A couple shops I've been to have little barrels full of Moss and Rem bbl's, all lengths, types, sights, etc for dirt cheap, probablt a good cond. rifle sighted barrel can be found for the cost of this ATI part. I'm not exactly sure the meaning of "mall ninja", but that heat sheild/GR combo brings the phrase to mind for some reason.
