What is the major difference? Just the front end having rails or not? Is the barrel different? I notice on wolverine they are selling some models as key model with heavy barrel. What exactly is this? I read that as a heavy barrel for accuracy like a heavy barrel in bolts??? Or is that not right?

How much lighter is the new model? I kinda liked the big bulky grip on the old one. I'm afraid the new one is too skinny and feel like a toy. Any thoughts on the new model? Does anyone own both? Which do you prefer?
 
I have the keymod HB, it felt about the same weight as the railed HB version. I've ordered some rail covers , to cover the keyhole. Mine is very tight, don't see no need for lock tight on any thing,as others have said.
 
I own the model sold just prior to the keymod. Love it. It is heavy, but I got big arms because I drum right.
 
The biggest portion of the weight difference is going from light to heavy barrel or vice-versa. A stripped keymod upper vs previous generation fully railed upper is a difference of ounces. It's weight up front, but its overshadowed by the massive difference in weight between barrels. The keymod with light barrel handles muuuuch nicer than the previous gen with heavy barrel.
 
I talked with Robinson Armament yesterday regarding barrel weights for the XCR-M as mine has a heavy barrel. They told me there is exactly 1/2 lb difference between the heavy and light barrels in .308 so I don't think there would be much difference in 5.56 mm either. XCR's are a little on the heavy side no matter what model you get. Hard to beat the ergos on these rifles though as I appreciate the controls even more than an AR.

There is a HUGE difference between going from heavy barrel to light barrel.
The light barrel XCR feel a lot lighter on the front and points way better.

I don't care what the numbers are, the difference is massive.. all you gotta do is compare the two side by side. All that weight is way up front on the rifle- it's a huge difference.
 
The lowers are not interchangeable from Quad Rail to Keymod Upper. Older lowers can be modified to fit the newer Keymod uppers, but then you lose the ability to re-instal the Quadrail version
 
Have the model just prior to key mod also, picked up a key mod with light profile barrel. Wow quite the difference feels completely different, like the feel of the narrower fore end. Have not had a chance to shoot one but I do believe one of these are in the running for next rifle purchase, sl8 or key mod light profile barrel xcr.
leaning towards xcr due to lack of need to modify to make use able.
Have a vortex strike fire going to try a vortex sparc on it.
Love the non restricted.
 
In November 2006 the firing pin was redesigned and made more durable and robust.
The first few hundred XCRs shipped with Yankee Hill Machine (YHM) back up iron sights (BUIS). The most recent iteration ships either without BUIS or with BUIS designed by Midwest Industries.
A 2nd generation adjustable gas system started shipping with XCR rifles in July 2007. The 1st generation gas system required tools (a 5/8" wrench) to adjust. The 2nd generation system can be adjusted by hand.[11]
The XCR's hammer was updated in July 2008 concurrent with the release of the 7.62x39 rifles/kits. The new heavier design allows the XCR to ignite some newer Wolf 7.62x39 ammunition made with extra-hard primers.[12]
In early 2009 Robinson began shipping rifles with an integral winter-style trigger guard and new paddle style safety. A provision for a quick detachable sling loop was added to the stock mount.
A two-stage match trigger is available which will break at approximately 3.5 lbs. This trigger can be ordered with a new rifle or retrofitted to an older one. The older one was a two-stage trigger that was about twice as heavy, and some complaints included trigger slap. As of May 2009, the new trigger has been shipping with all new rifles.
Ambidextrous mag release was demonstrated at SHOT 2010 and is now available.
XCR-L bolt assembly in 2013 made to be like the XCR-M.
Keymod released in 2013?
Overall you probably lose about 300-350g between the quadrail h bbl and keymod l bbl on the xcr-m; the weight makes a pretty big difference when it is ALL in front of your hand, but the light barrel keymod XCR-L handles as good as 90% of AR's I've played around with.
I would say just get the new keymod light barrel of whatever you want; it's like 2400 all in on a good day, and the machining quality is rather excellent.
 
trigger is different, bolt and buffer are different, firing pin are different. everything is vastly improved over the older models.

Good post. I checked Robinson's site and it says 7.5 lbs for the "L" light ( I'm assuming for the 16") barrel and keymod config. That's close to only a pound more than the lightest AR's.

I weighed mine and it came in at 7.2 lbs unloaded. It is the new keymod version and the balancing is perfect.

Funny you say that CS.

My original post stated something to the effect that the latest version of a KAC 16" is only a pound or so lighter...but then was concerned about how that could be interpreted, and so edited it : )

Anyways, both you and yuhaoyang talked about balance. As I age, I find balance more and more of an issue, and not just with hobbies : ) So this effort to "lighten the front end" is most welcome to me.

I heard you like balance so I tacticooled it so you can balance while you balance.
 
I only have experience with the XCR-M but I have an upper with heavy barrel and quad rail and a keymod upper with light barrel. The keymod upper with light barrel is a world of difference. The gun feels a million times more useable.
