The M4 and variants fire 5.56 x 45 mm NATO ammunition and are gas-operated, air-cooled, magazine-fed, selective fire firearms with a 4-position telescoping stock. Original M4 models had a flat-ended telescoping stock, but newer models are now equipped with a redesigned telescoping stock that is slightly larger and the end has a curvature. A fixed stock can also be fitted, but this is not a common practice in the U.S. military. The M4 Carbine with the newer, redesigned telescoping stock.As with many carbines, the M4 is handy and more convenient to carry than a full-length rifle. While this makes it a candidate for non-infantry troops (vehicle crews, clerks and staff officers), it also makes it ideal for close quarters combat (CQC), and airborne and special operations. It has been adopted by United States Special Operations Command (USSOCOM) and is the preferred weapon of the U.S. Army Special Forces. M4 have also been fielded by the Australian Special Air Service Regiment. Malaysia purchased M4 Carbine service rifles to replace the Steyr AUG service rifles in its armed forces in 2006. The M4 was developed and produced for the United States government by Colt Firearms, which has an exclusive contract to produce the M4 family of weapons through 2009; however, a number of other manufacturers offer M4-like firearms. The M4, along with the M16A4, has mostly replaced M16 and M16A2 firearms; the U.S. Air Force, for example, plans to transition completely to the M4 Carbine. The M4 has also replaced the M3A1 submachine gun that remained in service (mostly with tank crews). The M4 is similar to much earlier compact M16 versions, such as the 1960s-era XM177 family, though unlike them it is not intended to fire the earlier M193 ball ammunition. The United States Marine Corps has ordered its officers (up to the rank of lieutenant colonel) and SNCOs to carry the M4A1 carbine variant instead of the M9 Beretta pistol. This is in recognition that pistols are largely useless in current conflicts, and is in line with the Marine Corps phrase, "Every Marine a rifleman." United States Navy corpsmen will also be issued M4A1s instead of the M9, according to the Marine Corps Times.

    Not a bad transition for the USAF. Although many M-16A2's are still in the inventory, they are being phased out to be replaced by the M-4.

    I used the civilian version match target and Ive carried this gun for 10 years and it is an excellent weapon. Very accurate and reliable like and semi auto it must be kept clean but if your life depends on it I think keeping up on the cleaning is time well spent.

    I have carried the Colt 6920LE for several years and it has served me faithfully the entire time. I find that it works best with Lake City XM193 55gr FMJ or M855 62gr. FMJ. I use milspec mags exclusively, but have been pleasantly surprised by the new Magpul PMags - tested and proven more rugged than the HK high reliability at a cost of $17 ea. I bought 6.

    I have the Colt's Law Enforcement Carbine model LE6920. Currently manufactured models are built by Colt Defense which produces M4s for the U.S. Military. The only major differences are a 16 inch barrel, and absence of the burst mode on the selector. Mounted on my 6920 is the Trijicon TA31-RCO M4 or ACOG model identical in every way to the model I use in the Marine Corps. I zeroed my personal one with military M855 ammunition which is the current production "green tip" ammo with a 62 grain projectile complete with tungsten steel core penetrator. That is the ammuniton those carbines and optics were designed for. I found at home and abroad that once zeroed with the 62 grain ammo 55 to 77 grain projectiles will hit where you aim atleast out to 300 meters. Colt equals quality, dependability and ruggedness. I will never trust another AR/M16 make as much as a Colt because I have seen the abuse they have endured from being hit by high explosives in combat to being bounced down a stairwell or thrown out a window in bootcamp. There's my two cents and no I don't work for Colt, I just know what proven weapon can do for you.

    I miss this rifle greatly. Unfortunately due to budget requirements I have the M-16 A1 hopefully we can start fielding these. It's very light and compact with no loss of effectiveness with the shorter barrel. Anyone looking to arm their officers with patrol rifles need to give this a serious look.

    I carry one daily or a frankenstein version of an older A2. It works okay but needs a few upgrades. Well my issues ones do. I am issued a reflex 1 sight. Would prefer aimpoint and a t grip like on personal weapon. Unfortunately my so called supervisor in his wisdom had a block installed on all of them. So semi only and never allowed to go to any schools with our issues. Must take personals. A piston assembly would be better.

    I instruct AF personnel on the use and maintenance of the M4 and other small arms. It's relatively easy to maintain, reliable, and accurate. People say they "jam-up". Well they can if you don't maintain it properly as with any other weapon. Your weapon is your life. Therefore you must maintain it accordingly.

    I'm a big fan of the M4. I consider it and the AK74 to be my two favorite primary weapons. Obviously the M4 has the better manufacturing, grouping, etc. I think that every cop should have an M4 as their primary weapon, making their sidearm a backup.

    I carry an M-4 as my military issue rifle, and I personally own one as well (both are Colt). As with anything else, one can always find ways to improve the weapon (i.e. gas piston, larger caliber, etc.). But overall, this is a reliable and durable piece of equipment. If you take care of her, she'll take care of you.

    I have the civilian version of the M4 I beleive it is the 6920. I love it, I wish my Dept would let me use it rather than the issued AR-15A3. One is just as accurate and reliable as the other, but the M4 has less weight due to the fact it doesn't have the heavy barrel.

    I have to say that if I am going to carry a rifle in a war environment this is the one I would want to carry. The collapsible butt stock is very convenient when entering close quarters. It is also nice when long distances by expanding the butt stock and getting a nice steady aim. Very accurate.

    The collapsible stock and shorter barrel make this rifle much easier to handle in close spaces ie. vehicles, buildings, etc. The trade off is velocity and down range energy but for 300 and closer it's a good piece of kit.

    The forearm rail system and flattop upper receiver is excellent for mounting optics, laser aiming devices, lights, cameras and whatever else you can think to mount. Just don't add too much stuff because then it'll become unwieldy and cumbersome.

    Two things I suggest to upgrade the M4: 1) Go to 6.5 Grendel--better ballistics, down range energy and velocity. 2) Use a gas-tappet recoil system instead of direct gas impingement--better reliability and cleaner chamber area.

    Fortunately, you can purchase both as after market accessories. A little pricey but you'll have a damn fine weapon.

    I currently carry the Colt M4 Commando as my SWAT carbine. I have it equipped with a reflex trijicon sight, custom grip, and surefire light. I have not had any problems at all with it, and have found it to be reliable and accurate. Despite the "shorty" barrel, I find the recoil and blast highly manageable. I am extremely comfortable with this weapons platform. That said, I am not a huge fan of the 5.56. I would prefer the new 6.8, if given the choice.

I have also very successfully hit human sized targets at 300 yards consistently multiple times and my 25 meter zero groups would fit inside a nickel.

    A good weapon with some issues such as being lube thirsty but overall it's not to bad, just keep in mind to clean it weekly if not more or if you're in the sand box daily. Personally wish it had a larger round along with a better magazine system, which is usually the issue when mine misfeeds or jams.

    Familiar ergos, Mild-recoil, interchangibility, adaptibility make the M4 type carbine, including the Colt 6920 an excellent partol rifle to keep in the trunk. Many Depts. now have these and they are very polular for good reasons, they are dependable and accurate. Drop in a rail system and it can adapt to almost any mission.
