Remington LE booth is pretty quiet for some unknown reasons. They have all their military ACRs, XM2010 and their piston ARs available for viewing, which we had covered to death in 2011.
We did a quick scan and found the lightened ACR that they have submitted for the IC program. We like this version much better - lighter, "KISS-er" and now it can take on different AR grips. All the uselss features and weight adders are gone.
In comparison to the "fat elder sister" marketed by Bushmaster. They should just fold bushmaster and sell the real ACR under the Remington brand name instead.
