Gentlemen, I need your help again. One of the favorite rifles I own is a LE6920, it meets or exceeds all that I need in a PDW and is quite accurate at 50 to 100 yards. But, I go into my preferred gun shop today and find out they have 3 of the 6940's and are going to reduce the price to move them at this weekends gun show. I unfortunately subscribe to the belief that "If you have one, why not two?" Is the 6940 worth the expense? Of course if you can afford it. From what I got from the dealer its going to be around $1600-$1700. Based on your experiences with both, is the difference significant between the 20 and the 40? Does the fact that it does not have a Gas Piston influence the decision? Specs aside, who has a 6940 and how do they rate it against the 6920. I know there are better and there are worst ARs, so how do you really feel about the 6940?
Thanks:cool:

Neither one has a piston, they are both DI rifles.

The only difference between the two is the 6940 has a monolithic upper and folding BUIS.

If you like the Colt rail system the 6940 is fine. If you ever want to change things around the 6920 is much better for that.

Personally unless the 6940 price was an absolute steal I would not buy one. I don't see any real advantage over the 6920 at all unless you like Colt's rail.

I see 6920's going for $1250.

I have a 6940 and I love it. It would be an untruth to say it is BETTER than the 6920 more that it is different. It is really just he next evolution of the Rifle. The built in rail is a huge plus, however some people consider it a bit to wide. I personally would prefer it a bit thinner but to me it isn't so thick that it is uncomfortable. The biggest complaints so far seem to be that the bottom of the rail is held on by a system that may work loose over time. In addition you need a special wrench to remove the barrel. I have spoken with Colt and these will be available soon from authorized dealers.

It really comes down to personal preference. If you want a Monolithic style upper then it is a good choice. If this is not a concern to you or you don't care for the style of rail then a 6920 with a DD Omega rail may be a better choice.
 
$1099 is the best price I have been seeing 6920s go for these days. $1349 for the 6940. Do you want to customize your gun or just stick an optic and light on it and be done? If the former get the 6920, if the latter get the 6940.

Also, the bottom rail of the 6940 won't loosen up over time. It is pretty solid.
 
Thanks, I know neither has a piston, so I asked, since most manufacturer's are going to the gas piston as an option, would that influence your decision not to buy the 6940. What makes it better than the 6920, the upper rail only? I already have a 6920 and a Bushmaster Gas Piston rifle. Would the 6940 be a step up at a good price like $1600 over the 6920? I am looking for persons that have experience with both of the Colts and for their opinion.
 
Thanks that is what I was thinking. I have a ACOG on my 6920 and have never had a problem with it, but I wanted to see how tempting the 6940 really is.
 
What makes you say that most manufactures are going to Gas Piston? Of the companies that make ARs very few do Gas Pistons and only Ruger an LWRC have them as the main offering. Gas Piston is and will remain two things. A Novelty and a Solution in search of a problem.

That is not to say that I, and others don't like Pistons. Just that they are a complication on the design that isn't needed and they are not going to replace the DI system on most guns.
 
Both are pretty much equally dirty with a suppressor. Gas piston is cooler in the receiver area and not quite as dirty. But this is offset by increase part count that can cause issues.

That's not been my experience at all, especially with shorter barrels.

The LMT piston carbine has less parts than a DI carbine. The gas piston HK 416 ran with much fewer malfunctions than an M4 in government testing.
 
Went to the local gun show yesterday and today, (why go once, you might miss something you need.) The LE6920 was $1299 and the LE6940 was $1500, with a big sign saying "Ask us we negotiate", I thought I had been transported back in time. As to who is offering Gas Piston rifles, I see quite a few manufacturers, Sig, Ruger,POF,Adams Arms,Bushmaster, etc, I do not think it will replace a well made DI, but I am glad the options are out there. Back to the basic question , is the 6940 worth the extra expense as per reliability, accuracy or is the 6920 and a few bucks for a quad, a more prudent investment? It's very interesting how these threads seem to have a mind of their own as to where they go!!:rolleyes:
 
no difference in reliability. a tiny, theoretical difference in accuracy due to potentially stiffer receiver on the 6940, but that is totally, utterly obscured by the chrome-lined, blaster barrel.

if you're looking for accuracy, pick a different mfg.
 
A good free float quadrail will run you about the same as the difference between the 6920 and 6940. As I said before, it really comes down to if you like the monolithic rail and if you want something a lot of other people don't. I paid more than 1500 for mine a couple months ago and don't regret it one bit.
