From what pics Ive seen the M4 isn't really at an advantage considering all the shit those guys have hanging off of it. Barrel length of course is understandable. I carried a 60 so all of this was a nonissue  That shit makes the rifle far better than 5 inches of barrel ever would. |

Yea, all that crazy "tactacool" crap like IR lasers and lights to deal with darkness. Totally useless shit. Exactly. It's also ridiculous because they haven't been using those same accessories on the A4s. The extra 5" of barrel and 600FPS totally makes low-light accessories and optics completely pointless. 
20" gun threads are almost as stupid as KISS threads. |

Because huge, long rifles suck. Most killing happens with crew serves in the military. Most civilians don't need a rifle that makes shots at a few hundred yards. Shorter guns are cooler. Smaller guns suit people's needs better, such as home defense or truck rifles, Suppressors are more popular that ever. Not to mention, modern ammo is a lot better, and often designed to work out of carbines, so the velocity loss isn't as big of a deal as it used to be.
There are lots of reasons why people choose shorter barrels. |

My first AR was a 20" based on OP's train of thought. After buying a 16" later on the 20" collected dust until it was sold. As a civilian I do not need a gun that is lethal to 600+ yards. The extra size and weight of the 20 sucks and doesn't give me anything. For troops I don't see what it really gives them either. Especially when you consider that they fire thousands of rounds for every 1 hit. I wish I could recall the exact number but it was pretty crazy. For the most part their SOP isn't to take aim at a bad guy and pull the trigger. They point the end that goes bang in the direction of the enemy or sound of the gun shot and they pull the trigger a bunch. And before someone corrects me I realize not all engagements are like that but the ones I have seem on liveleak all seem to be that way.

The 20 inch variety M-16 was a 1-14 and then 1-12 twist designed for the 55 gn round. The M-4 and newer M-16 went to 1-7 twist for the M885. Since most engagements are within 100 meters, the shorter bbl is better.
Frankly, I prefer my AR-10 carbine. I do have two 5.56 long guns; a 16 inch version and the Tavor. I don't need any more of that caliber. Have one AK which is a nice tool and does what it was designed for. My precision bolt gun is only a 20 inch bbl .308 Savage 10TR. It will go as far as I want it to. No need for the longer bbl AR in the real world. |

Sandbox? Asked for a harder hitting round? Where do you get this crap? lol Across the board, no one asked for anything. There is always a small group that will ask for different things. There's nothing wrong with the rifle and ammo we use now. That 20 inch is too long and gets in the way. |

In a nutshell, I own ARs for knife fights. I have no need for maximum hitting power at 600 yards in a defensive rifle or carbine.
If your preparation includes scenarios where things have gotten so bad that you are shooting defensively and offensively (longer range), then by all means, own at least one SPR. Plus for a lot of people a shorter carbine is just a hell of a lot more fun to work and play with. M4 is a sexy weapon. |

My favorite and softest shooting AR is a mid-length 18" med-contour with adjustable gas. But it's a tad heavy and slightly unwieldy when compared to the 8.5" AR I keep next to the bed, and the. 14.5" LW AR in the corner.

I don't have much use for the A2/heavy barrel 20", would be great for a SPR build but if its 20 and not a precision rifle I will choose a M16A1 every day of the week, light or lighter than the m4 and feels like a rifle when aiming.
The real advantage of a 20" over a carbine is the Iron sights, have abosulutly no problem hotting steal with irons out to 200 with 20" rifles, I have seen people with carbines have trouble hitting 12" plates at 100 resting. |
