It's ridiculous. It would add so much weight to the front of your gun it would be exhausting to handle it. After 10 minutes of lugging it around you'll have had enough of it. It looks good, but it's a solution to a non-existent problem.
There's no doubt, it's a show stopper, and it's ideal for trick shooting, but it has no practical purpose and it would lead to an incredible expense of ammo to be happy with it.
If you have the money and decide to get it, great for you.
Keep your eyes on gunbroker.com for the next year or so, and see how many of these end up for sale because the guys that bought them get tired of them, or need the money for other more important or more valuable things in their collections.
I guess I'm just an old man that's wasted enough money on toys and trinkets. I've decided practical accessories have a bit more value. Over my lifetime I've given away thousands of dollars worth of stuff I though was ideal (Especially for my AR-15), but after a short while it sits around collecting dust or taking up space. And that includes dozens of holsters, a few guns, and plenty of gun accessories, including grips, scopes and a few lasers too.
I've discovered that less complicated and lighter, is usually better.
Most members here are also members on other forums. Have you ever sold any of those types of accessories, because you discovered it isn't nearly as cool as you thought it was, when it was on somebody else's gun or you saw it advertised? Or you've seen somebody else post an item for sale, because it didn't fit their needs either? That's what happens to most of the stuff that looks so great, or has top notch advertising programs.
I'd rather buy a great gun once, than buy all the cool looking accessories in the world.
Just my $.02 for the evening.
