People sleep on it because they just don't know - IMI Defense Enhanced M4 Stock Mil-Spec

I didn't even know IMI made stocks... so I took a chance on it and wow, I'm glad I did. It's so robust and well-built that I was quite surprised. I'll buy several more of these. They aren't loose on the buffer tube but they aren't extremely tight on it either like a B5 Bravo or SOPMOD. It's really fine though. If I had to guess I'd say they make these stocks themselves rather than having an OEM just slap their logo on them. Their fit seems to be tighter, the polymer seems to be more dense, and the spring seems to be a bit stronger. Take that with a grain of salt though, I only have one other M4 stock. They also come with a sling swivel and that is also why I think they make them themselves. It's a great stock. Buy one, you won't be disappointed!
