I'm having a hard time deciding between which ar15 to purchase; the Colt LE6920 or the Colt LE6940.
Just simply want something for sport not so much for hunting. Something that's reliable, holds its value, and is fun to shoot. I would also prefer one that allows for upgrades. I'm pretty much set on Colt but just can't decide between the two; any ideas or personal experiences?
New to the sight/forum so thanks for any feedback. Also, this will be my first AR15 purchase so any additional info will be greatly appreciated as well. Thanks.

I'd lean towards the 6920 since it's more flexible for upgrading, unless you're happy with the monolothic rail and goofy flip up front sight on the 6940.

Really? I would've have thought the 6940 would be more flexible for upgrades.

The flip up sight was the main thing I didn't like about the 6940; and what exactly is the benefit of the "monolithic quad rail"?

You're kind of limited due to the proprietary barrel nut and lack of a wrench available to the public right now. The 6920 is the most upgradable Colt available right now. Personally I'd wait a couple months for Colt's new lightweight Carbine from Clydes Armory.

6920

I struggled with this one a lot actually. I was considering a 40 to replace my 20. The 6940 is a great weapon with a lot going for it but... when i actually put my hands on one, i realized you're pretty much stuck with a carbine length gas system, and with a shorter rail.

I bought a BCM middy with a Larue free-float to supplement my 6920 and that was that.

Not in the least.

You must be weighing it with your eyes.

I will vote 6920 but just because I love mine, and I want to be the one to pick upgrades.

Edit: Welcome to the site, and good luck with your choice. You are now obligated to provide pictures of whatever you buy since we helped you out.

I like my 6920, but I would not mind having a 6940 to compare it too.

Here is my Colt 6920, with a Eotech 512, Eotech 3x mag., Magpul ACS in FDE, D.D. 7 inch rail, and other mods with my 5.11 RUSH 24, and M40 mask.

Upgrades by this week, Brownell`s oversized mag release. BCMGUNFIGHTER Charging Handle with Mod 3 Latch (LARGE), Ambi safety from BCM (unknown maker), and I am trying to find a Magpul B.A.D. in stock somewhere for next pay.

I bought my first AR15 a few months ago and i wanted a Colt. I was torn between the 6920 and 6940 but i didn't like the goofy front sight on the 6940 so i bought the 6920.

So i say get the 6920 im really happy with mine!

6920 because you have the ability to install almost any rail you could want & you are not stuck with a monolithic with a proprietary barrel nut + that 6940 front sight.

Ya but with the 6940 you know you got colt hand guards ;) I to like the versatilty of the 6920 more. But the 6940 is fine to.

The only thing I do not like about the 6920 is the factory front sight. So that brings me to this question, Is there a way to remove the whole section of the front sight, and replace it without causing any problem with cycling? If so how? I am kinda new to doing that type of upgrades and replacements to firearms.

Wish I could buy both; that'd be nice. I was leaning towards the 6920 from the get go, but the place I was going to purchase had a sale on the 6940's and he recommended that one because it's more versatile for different sight/scope set-ups. However, it seems with everyone's feedback that's not the case and he may have just said that because that's what he had in stock and would've had to order the 6920.

Remove the FH & then drive out the taper pins at the below section of the FSB. Install a .750 low pro gas block with a longer FF rail or install a railed gas block & keep keep the original handguards. It's really easy.

I'm not looking for Colt rails. I use DD rails!

Is there any links on step by step instructions on here? Or pics (before and after etc)?

Either this or cut it down into a low profile. Both work fine.

Bravo company posted some basic instructions on removing the pins to remove the f2 sight. Would be the same on the colt.
