I have the original 6940 myself. Apparently worth some big $? I didn’t know Colt stopped making them for a time due to legal issues with LMT who has a patent on the design:

Those guns were Laser Beams. Pappabear had one and sold it for some insane reason. Shot groups that were too small I guess.

Looks like my LE6940 with M4 markings and no patent number is worth more than I thought.
I only wish they would also start making the damned barrel nut wrenches again so it can be serviced properly.
LGS has one for $1338. I thought Specialized Armament had the wrenches, but that was long ago.

Yeah, they no longer have them. That was the first place I looked.
Knowing Ken, that means he’s only got 40 of them and won’t let go. 
I swear that guy likes having inventory more than he likes making money.
I have a 6940P labeled “Colt Piston Carbine”. I put a very few rounds through mine but agree with @markm; these are very accurate rifle. Mine has been a safe queen for too long because these were very limited production, and I was concerned about spare parts. I need to revisit this and see if spares are available. I seem to recall that some SME (maybe Larry Vickers?) opined that the Colt piston system was very good. One way or the other, mine was very accurate, reinforcing the intrinsic accuracy of the 6940 design.
I was not aware the 6940 was developed to compete in the SCAR program against the FN. They should have gone with the 6940! The FN SCAR 16 didn’t last long. This gent worked at Colt during the development of the 6940;

Wow. I didn’t know that either.

I kinda liked that carbine, never owned one though. The flip up front sight kind of turned me off, which was just silly on my part I suppose.

Me too. I’d own one if I got a great price, but the flip sight was not my favorite either.
Kinda silly of both of us ain’t it? Pooh-poohing the back up front sight on an optic oriented carbine. Makes me feel kinda judgy. 
ETA: Given the choice though I’d still go with the LMT MRP.
Is there a major $ difference?
LMT is more $$. But the barrel selection is pretty good, gas or piston. Available quad or mlock, in 9.5, 11.5, or 13.5.
And, not to rub salt in the wound, I can get a T-30 anywhere.
Aim just listed LE trade ins for $999
I always thought they should have equipped these with a SOCOM profile barrel.

Jesus! Glad I don’t have a 6940.
I’m casually in the market for a 6940 and if I get one I’m putting a SOCOM barrel in it.
Totally agree, the 6940 with a 14.5 Socom and I’d buy in a heart beat, a LGS near me has one but they want almost $1600 for it, and I just cannot justify another 16" for that price when there’s so many other things on my priority list

Mine is a colt m4 SP6940 sporter. Thought it was an LE 6940, but nope. Not sure where that falls in the history of the 6940, but it’s my all in one HD/SHTF rifle. Just added a Vortex 1-6 SOPMOD that replaces the old aimpoint classic patrol RDS for some added reach. Got a great price on the Vortex.
