Okay, I've been looking for a really good mil spec AR-15 (m4). I mean as close to the military grade m4 as possible (minus burst and full auto of course). I have been looking into the Colt LE 6920, but I've read that the barrel is longer. I read that colt is really good, and is the brand many military us. Is the Colt LE6922 the right barrel size?

Also, I've read into the ammo it uses (.223), and was wondering if that's the ammo the military grade ones use because it's such a small caliber, I was curious. Thank you all for any answers.

Lots of options/brands that are "best" and Colt is not always the name that surfaces...

Check out http://www.knightarmco.com/ as a example, KAC sells tons to the military....

What is "mil spec" and how do you define it...

If the military buys it does that make it "mil spec"

Oh. Basically the same specs that the military uses in their m4's (minus the full auto/burst fire).

As far as the ammo goes, if it can fire 5.56, it can fire .223. If a rifle is designated as chambered for only .223, I don't believe they're recommended for firing 5.56 (if I'm incorrect on that one, please let me know).


Just out of curiosity, are you looking for something that is truly mil-spec for a specific reason? Or are you really just trying to get something that is as reliable and as solid as what the military uses?

Oh okay, So the military uses those two cartridges? The reason I ask is because it's basically a 22 caliber, which is pretty small...

And the reason is because I think they are the coolest looking, and because I want more what they use because I can trust it to be a higher line, and so I can basically say that it's what the military uses. I really love the m4 and always have. It's my favorite gun, and I just want it to be what the military uses because it is originally a military weapon.

Whoa there. Define "tons". Also, define "military". There are two contractors currently providing complete rifles to the US military. They are building to "mil-spec", which is using the materials, dimensions, and testing mandated by the military. Those two contractors are Colt, and FN. Some other manufacturers may build a few guns for this or that, but adding ALL of the tiny contractors output together wouldn't equal even a tiny percentage of what Colt or FN sell to our military.

I have the colt le 6920....it is chambered 5.56 nato....1/7 twist(so you can use heavier bullets)....i shoot .223 through it no problem.....the other way around could be( .223 and 5.56 are not identical)....and if u buy military 5.56 it could be higher pressures(they are used in machine guns)...dont ever use steel case......dont care what anybody else says.....but i do agree u can find a good quality ar for cheaper than the colt.....i think my colt was 1200(?)...anyway i think the colt le is very close to the m4.....

Despite the tangent that Rampy went on, you are asking about something that is as close as possible to the Colt M4. There is a spec for the M4, developed by the Army and Colt. It is known as the TDP (Technical Data Package.) Colt makes all the M4s for the US military. As mentioned above, the M16s, currently in the M16A4 generation, are made by FN and there is a TDP for them also. While the military may buy small quantities of other weapons, such as the KAC SR25, a version of which is known as the M110 Semi-Automatic Sniper System, the majority of rifles come from Colt or FN.

While you can debate the meaning of "best" as it pertains to AR15s until the end of time, and not satisfy everyone, the weapon closest to the M4 available to the normal citizen is the Colt 6920, in either the LE6920 or SP6920 model. The only diference between the two is the LE model is marked "LE/Military use" and LE Carbine, while the SP says Sporter and M4 Carbine. The only difference from the M4 is the semi-auto Fire Control Group and the 16" barrel instead of the military 14.5" barrel. The barrel is lengthened, because the minimum barrel length for a civilian rifle, including muzzle device, is 16". A military M4, with a flash hider, is less than that. You could get an LE6921, which has a 14.5" barrel, but then you would either have to get a long flash hider permanently attached (to get to 16") or get an ATF SBR (short barrel rifle) Tax stamp which costs $200, along with a lengthy approval process.

Below is a picture of my new SP6920, showing the "M4 Carbine" rollmark

As for for .223 ammo, the military actually uses a higher pressure (non Saami) version, known as 5.56 NATO. The militay uses M193 55gr ammo for training, M855 62gr steel penetrator and M318 OTM for general combat use, and Mk262 77gr BTHP ammo for long-range snipe and DMR duties. There are also various tracer and blank rounds, but the 4 mentioned above are the main types of military ammo.

This is the problem I ran into and probably most first time buyers of Ar-15 style rifles. There are many opinions of what is the "Best" rifle or carbine. I think it is easier to find which are the worst. When I started seriously looking, I ended up with a Colt LE6920, for a little less than $1200. It is, "mil-spec" , which really means it is built to the specs the military has established. Parts that are "mil-spec" should interchange. The reason, I went with this one, I liked the look and feel of it, and its the one rifle everyone compares, to; as in, "Mine is better than a Colt" "Your's isn't as good or well built as a Colt", etc. So, I bought a Colt. I am very happy with it, no problems with it whatsoever. No ejection issues, fail to fire, fail to feed, no magazine problems, just fun shooitn'

In fact, today I sighted in my Aimpoint PRO, also pretty cool and easy to do. If you want a Colt, buy the Colt and be happy. By the way, I do understand that Colt is no longer going to market the LE6920 to civilians, the changing the rifle to SR6920 or something, but it is the same rifle, just different markings.Posted Image

Colt never marketed the LE6920 to civilian non-law enforcement buyers. They always marked the SP6920. The difference was only the markings. In fact, Colt used to have a policy (I don't know if it was ever rescinded) that any Colt authorized dealer that sold an LE6920 to non LE, would not be an authorized dealer for very much longer. Many did it, and got away with it, but I do know of several dealers that at least got nasty letters from Colt, threatening to not sell them any more guns.
