New guy with a question

[Sry0fcr]

Well, the Trooper is a no go. Colt is out of stock and every place I've tried is the same. No distributors have any in stock and no one can order one until Colt makes another batch. So I ordered a 6940 instead. Should be here within a week.

Nothing wrong with a 6940, but you're married to that 7" monolithic rail. The 6920 OEM #, 6920 EPR or the 6960 would have been more versatile choices IMO.

I wanted the rail. That's why I was looking for a Trooper.

Are we taking about the same thing? The Trooper LE6920-R has a 13" free floated M-LOK handguard from Centurian. The LE6940 has a monolithic upper receiver with 7" picatinny rail. So sure, they both have "rails" but one is arguably too short for proper hand placement and is integrated into the receiver... Unless you meant to type LE6960?

Yes, that's what I meant. I know the difference. The 13" rail would work but I don't need one that long.

A friend recently bought a Colt M4 Carbine and let me try it, and now I want one. It was the first time I'd shot any type of AR. Last 'black rifle' I shot was an M16A2 when I was in the Army (got out 25 years ago). I like my friend's M4, it functions flawlessly. But the M4 Trooper caught my eye. I started doing some digging and I'm running into lots of terminology I've never heard of. What's the difference between a mid-length gas system and carbine gassed? And which does these two have? I heard someone say mid-length is better but I don't know why.

I'm not the one that usually does this, but, respectfully, you don't know what you don't know. If you've never heard that phrase before, think about it.

Unless you are goinf to spend your time shooting with your support hand grasping the mag well, or holding a VFG like a pornstar, a carbine length rail is not going to be long enough if you put any ancillary equipment on it such as a light.

If you look around the world of real shooters, whether you believe that is our SOF soldiers, 3-gun shooters, or just top level trainers, very few of them, if any, are running carbine length handguards/rails on 14.5 or 16 inch rifles.

The primary reason for that is that the longer handguards offer more to the shooter in terms of ergonomics, regardless of how you shoot.

Since you probably can't undo what you've done, even if you wanted to, I honestly don'y know why I've posted.

Enjoy your new rifle, I'm afraid if you shoot it much and evolve as a shooter, you will be looking for a new upper soon.

Then why does everyone recommend a 6920 as a first rifle?

Because it's a known quantity that works and because you can always put on a low profile gas block and the handguard style and length of your choice, not so with the 6940; you're stuck with the short rail until you buy a new upper receiver.

Okay, that makes sense. But I don't see that being an issue at this point because I liked the way my friend's 6920 felt with the short handguard when I was shooting it. That's why I said a longer one would work but wasn't necessary.

But I can see the other points being made here. If I do change my mind about that later, I can deal with it. I'm not averse to making changes as necessary. Costs some extra money to do it? Yeah, but that's the only downside I'm seeing. I've had to spend money to make changes with plenty of things before (guns, cars, electronics, etc). That's life. For now I like what I see and I'll just roll with it until/if I change my mind. If that happens, then I'll make the necessary changes. I appreciate the constructive criticism, I'll keep it in mind as I go.

Fair enough. It may not be ideal, but it'll still work. If you're going to slow fire rested from a bench it probably doesn't matter anyway.

I would think the other way: the more you train, the more you will realize most “accessories” for the AR-15 are just there to make money. There isn’t a lot you can’t do with a stock 6920, sling, light, and optic.
