I belive what your friend was referring to is a hydrauluc buffer assembly. It will improve you rifle in too many areas to list here. Checkout the Enidine AR-Restor Hydraulic Carbine Buffer at http://www.buffertech.com/AR-Restor-Hydraulic-Recoil-Carbine-Buffer-P178.aspx
GI’s and Jarheads (Semper Fi!- no insult intended) are changing to these as fast as they can get their hands on them. The key word to these units is weapons reliability. Not to mention, actual reduced recoil, smoother operation, increased accuracy in fully auto, etc., etc.
These are not a gimmick and really do...do what they say. It will cost you about $89.00 which is cheapo for the improvement you get. Most of the improvement is firing; using one of the buffers in a scoped, fully auto version. Best though is Hundreds of percent improvement in reliability. That’s what the pro’s want.

This is the first I’ve heard of it. Got any links to official sources?
I’d like to see the tech data that validates this claim from your link:
“AR-Restors greatly reduce felt recoil and improve accuracy.”
