Where to find this barrel/flashlight clamp?

Does anyone know what brand of clamp this is? It's all plastic except for the bolt. Just a cheap clamp but it's the only thing I have found that works well on my M4 and is easy to take off for cleaning.

Looks like an ATI. I found one at Wholesale a while back.

Oh okay that makes sense. Thanks a lot. I bought a bunch of cheap and expensive plastic and metal clamps for my 870 and thenew later tried them ob the M4. This one works so well but I think the plastic is going to give at some point.
