I bought this to use with a Hi Point 9mm carbine. I couldn't find a lot of information about which scabbard would work well for the Hi Point. Well, it fits great in this thing. The only problem is that the carbine is so unbalanced and heavy on the stock end that it doesn't shoulder very well in a scabbard. It's not the fault of this product; it's the gun. I haven't tried this with my AR-15 yet, but I suspect it will work well. Time will tell, but it seems well-constructed and durable.
