Okay I'm wanting a new gun, and I basically just want a few expert opinions. I've narrowed it down to these two.
SP = Sporter MT = Match Target

SP6920:


MT6700:

Do you want a rifle or a carbine? Most here are going to recommend the 6920, but if it was me, I'd get the 6700.

I would get the 6920 because it is more versitile and alot more pleasent to carry, you carry an HBAR a few miles and you will see what I mean.

One is a rifle & the other is a carbine. First you need to explain why you would want one over the other & what you intend to use the gun for before anyone can give you advice. Personally I would get the 6920 because I only use carbines, but I'm not you. Please give us some more intel about your uses for one or the other.

They're very different, some people would say get the 20" barrel for long range shooting and the 16" for tactical shooting. The 6920 is alot smaller and lighter

@ TheMercenary - thanks I changed my post.
@ 86HMMWV - I mainly want a rifle, I'm a fan of the M-16 look. But the Match targets don't come with a lot of the accessories the Sporters do.
@ warpig8654 - Mostly I'll just be using it for target shooting and plinking. I also do expect to modify it a little bit such as the stock and sights.

However I still like carbines just as much.

One complicated part about the AR world is that, if you have no access to them, you don't know what you prefer. These days, I would guess carbines are more popular among civvies. It’s usually at least a pound lighter and shorter. For most of the shooting civvies do, you really are sacrificing pretty much nothing. To expand on that, in the Marines, we qualifed at the same distance with the m16 as we do with the m4(as far as 500m). So how much distance are you REALLY sacrificing? The answer for most people is none, because they won’t be shooting farther than 300ish, which both are more than capable of shooting at. So as civvies, its easy to think: why NOT go shorter and lighter?

Another thing to keep in mind is that there is nothing that can’t be changed. Make your guess as educated as possible, and if you change your mind later, it’s an easy swap.

Best of luck! Hit us with any more specific questions you might have.

it's the carbine all others are judged. if you want a 20" i would go with a BCM. just my opinion.

If the 6700 had a 1/7 barrel, that's what I would get.

The inability to use competition bullets + the hbar is mind bogglingly stupid to me.

For that reason, I'd get the 6920.

ETA: Jus as a warning, the 6700 will weigh about 8.5 pounds stock. This is about 2 pounds more than the stock 6920.

Get a 6700 and a Colt A2 barrel assembly and you have a nice M16A4 clone..you can sell the HB off that's what I did

and get a 6920 as well..

the 6700 i sheavy, it has a HBAR that you will tire of, mainly if ( and you will) want to add things later

it has a 1/9 twist, fine if you dont want to shoot heavier match or even better quality hunting military ammo.

its longer, it offers no real benefit with the extra 4 inches of barrel. the 16 inch barrel will be just as accurate with a tiny loss of velocity

it may be harder to find too because its not popular adn not many places carry them


the 6920 can do everything the rifle will do, but be smaller, lighter handier, balance better adn has a 1/7 twist that allows the full range of civilian to military and match ammo from 40 grain bullets to 80 and above if you choose to handload though 77 grain is the practical limit for anything other then camp perry

My SP6920 carbine




For my 20" rifle I went with a lighter profile barrel with my USGI Colt M16A2 upper half on my 6601 lower

I agree with the others, get both, but after you got them you'll want more, that's black rifle disease for you.

I would suggest getting the carbine first because you could do more and modify it more to your liking, then later get a rifle but I would recommend a lighter barrel than a HBAR or if you want a heavy barrel for target and hunting get a precision SS barrel to replace the factory stock 6700 barrel.

With my SP6920 I just upgraded it to the minimum that I need which is just a drop-in KAC M4 rail to hold my Surefire light and VFG, also Aimpoint, BUIS and a good Vickers 2 point sling that's it.

I went with the A2 type for my rifle to be different with my carbine and to challenge myself shooting iron sights, also it reminds me of my former Colt SP1, SP2, and A2 HBAR rifles.

You could buy the 6700, and then buy the 6920 upper half kit from Colt's site. Then voila! you'd have both

And then, as time and budget permitted, you could put together a lower half and have two complete rifles. It's a win win situation.

I have both a 6920 & 6601 HBAR. Try to shoot them both and decide from there. I wouldn't select one of mine over the other, each has it's advantages.
My inexperienced shooting neighbor prefers to shoot the rifle much more than the carbine FWIW.

No, it won't. Colt rifles and carbines are hovering right around 1000 dollars. Last I checked, the only "popular" brand that routinely beats that price is Spikes.

As far as picking one, here's the deal.

The 6920 is a light weight carbine. It weighs 6 pounds stock. This is a little too light for my taste. Makes it more difficult to shoot offhand for me. It does however have a 1/7 twist barrel capable of shooting the premium 75-77 grain match bullets and the modern 75 grain law enforcement/self defense ammo. This would be optimal for a self defense gun, truck gun, and a carry gun if you have the need to carry an AR15 hiking for self defense (a much bigger probability in rural AZ than in WV I imagine).

The 6700 is a rifle wtih a heavy barrel. It weighs 8.5 pounds stock. It is "front heavy." I dislike hbars for "general use" because 8.5 is about as heavy as I'd want to go, and it puts too much strain on my left hand when shooting offhand in 3-gun. I prefer hbars to have lead weights added in the stock to increase balance. Anyway, this rifle has a 1/9 twist barrel, which in my opinion is retarded. It may not be able to shoot the heavy match bullets, which in my opinion is generally the whole reason for getting an HBAR barrel. That said, heavy guns are easier to shoot accurately than light guns. Also, it will have more velocity.

I went with the "best of both worlds" and got a Colt 6551 used. It has a government profile barrel, and is a well balanced, 7.5 pound rifle. If this is appealing, I'd recommend you go with bravo company, as they sell such an upper/rifle and Colt does not.

Did you look at the MT 6731?

Both are excellent. You're not really going to go wrong with either. I have a 6940 carbine and a 6601 match target so I can appreciate the differences. You should probably just get both and be done with it.

If I thought I'd really need it for SHTF –– like actually shooting in the shreets n shite..zombies.... fallujah... .then probably the 6940. It's lighter and has the adjustable stock. But then again, if you had to hit someone in the face with the butt of the stock, the MT would probably be better. It's heavy.

For sport use at the range... I really like the 20" barrels for the added velocity and accuracy. Also, I've noticed the 20" barrels are just a tad quieter. The full size stock is also very comfortable and is always ready. But that's probably a negative for shorter folks.

People say you have less failures with the longer rifle length gas system. It's said the carbine shoots the BCG back so fast and it springs back so fast that the magazine doesn't have time to properly feed a round. I've not had that issue, but it makes sense and I'm sure people have experienced it, otherwise carbines wouldn't have heavy buffers and internet posts about them messing up.

My 6940 has the 600 meter range sights while the MT has 800m sights. That may be an issue for you if you like to shoot long range.

The carbine is more popular these days and the 6920 is pretty much the defacto gold standard. You would have zero issue selling it if that were a necessity. The rifle length MTs are just not as popular these days.

Which one do you like the looks of better? What are you going to use it for? Just at the range or hiking over miles and miles of farmland? That would make a difference too...
