I finally got the ACS mounted it feels great and I think it looks great. The only bone I have to pick about it is... 1)The stock still has some play in it even when you clamp it down. This may be normal but I just thought it would be tight with no movement once clamped down. 2) The battery storage tubes are waaay to big. When you put AA's in them they just rattle around and it gets annoying. If they would have made the tubes ID the same or closer to the Batteries OD then it wouldn't sound like a babies rattle. In any event I just put some batteries in the side storage with a little piece of foam, no biggy. I still would buy another one, these are just two things I expected to be different. Overall I love it and I'm satisfied...
Heres my ever evolving AR I'm still waiting on an ASAP sling plate and an enhanced butt pad (backorder), after that I think I'm done and will move on to my next project (M4)
