When looking for an AR-15 that meets (all?) SITUATIONS.
Most people are looking for a compact ar-15 for mobility. THE 14.5 m4 carbine is compact but the ammo doesn't have full burn, and a shorter sight radias. The 20 inch AR15 is great for full burn and rifle length sites but not very mobile in autos. The 16 inch ar15 is better for mobility but still doesn't have full burn or rifle length sites. In my opinion the answer is the 18inch AR-15 and Collapsible stock only 3.5inches longer than the m4 carbine. Better velocity and more mobility and rifle length sites. www.cmmginc.com makes several http://cmmginc.secure-mall.com/shop/?shop=1&cart=1183615&cat=32& Then tab down the page. OPINIONS AND COMMENTS WELCOME  |

In my opinion at real combat ranges even an 11.5 barrel would do.Full burn on the ammo to me really wouldnt matter if gunfights are taking place at 15 to 40 yds.Thats why my go to ammo are hollowpoints but even at that range im sure ball would be fine to.

IMO anything longer than 11.5"-12.5" for 5.56 is just going to be excessively long and nose heavy when you add the inevitable silencer.
If you want a bullet to fragment over the 100+ yards that this barrel length already allows for optimal results then step up in caliber. Denny sells a great 12" 6.8 barrel and Noveske has a 12.5" 6.8 barrel. If you want even more range than that (now you have over 200 yards of range where more than one loading type still fragments) I think its more of a dedicated long range/precision rig and all you need there is a 16-18" 7.62/.308 rifle. If you need more range than THAT get a bolt gun. Also what does "full burn on ammo" mean? If it means all the powder is burned not even a 20" does that. Iit means you have reached maximum velocity not even a 20" will do that either. Even an 11.5" barrel can have pretty much nil on flash with a good flash hider. Finally... who needs anything more than a carbine iron sight length since its just a back up sighting system. Use optics and its a non issue. This is MY "do it all" rifle. Id still like to tweak it a bit more. 1-6X scope instead of 1-4X for a bit more precision at range, a UBR to help balance the silencer a bit better, a barrel that does 1 MOA instead of 1.5 MOA, etc. Its approx a 12" barrel, its the same length as a 16" plus flash hider with the silencer mounted. You cant see any muzzle flash with the silencer off and it plenty handy in tight confines with the silencer off.

10" to 11.5" in a SBR lower. I vote for Colt LE6933
Except for an all out war on American Soil (save SHTF or Teotwawki), where would 50+ yard fragmentation range be needed? If your taking out people at over 25 yards, I wonder if you could even justify a life threatening event. my 2 cents |

I have used a 18" Mod 01 SPR for a while and felt it was way too long and nose heavy WITHOUT a silencer for use in close. I only have one pic of that rifle and it was a goofy pic you might have seen before. Even when set up as it was supposed to be it was just too long and nose heavy for a "do it all" rifle.

For my purposes, the "perfect" AR would be similar to a C7A2 with a TA11E ACOG and plenty of good mags full of Black Hills 75 grain OTM. I'd use a LMT Crane SOPMOD stock and would probably free-float the barrel and add front and rear Troy BUISs.
I'm probably putting too much weight on the ability to make rounds fragment consistently out to 200 yards, but so be it . . .  |

I'm not much of a suppressor person...yeah I've used them. Not as many as others, but enough to know that they aren't worth the hassle...for me.
16" midlengths work fine for me...or carbine length... My favorite is my A4 clone. Don't know why, esp. because I traded in my A4 for an A2 after they took my M4 away. Too heavy

I wonder why it is nose heavy
. I don't think there is a prefect AR15. Pick a yardage . Do you want to get a can? Do you mind pinned on flash hiders? Is this to be fired out of a car window or prone in a field? SBR,SPR,CBQ? Your looking for an adjustable wrench when you need to find the correct wrench.

I'd prefer an 11.5" with a LMT SOPMOD and and TA50R-4.
Perfect setup for everything that wants to do me harm.

There isn't one for all situations.
The 18" does most any task, but not ideally. A 10-14.5" Carbine is generally more effective within 200m, even if the wounding ability is dimished somewhat. With a wider caliber, this limitation would be diminished as well, so bear in mind that 'perfect' may very well be a 6.8SPC close range SBR, paired with a longer range unit (18-21" in 6.5-7.62 caliber)... Then again, I have a CMMG 18" upper - love the thing, but now I'm finishing up my 14.5", which I'm suspicious will get more use than my 18" (as nice as it is) |

Sometimes 55 gr bullets may or may not break at the cannelure even if velocity is at the required 2700 FPS to do so.People come in all shapes and sizes and what may fragment in one person may not in another.Hoping for fragmentation for performance should not be reliably counted on.You have better dependability with hollowpoints.

If you bullet doesn't fragment, you will just be punching 22 cal holes in your target. Fragmentation will do maximum damage. At what distance this occures will depend on your barrel length and bullet construction. |

There isn't really a perfect rifle for all situations only compromises.
The "recce" is a compromise concept meant for a do it all rifle. I think perhaps the perfect AR-15 type rifle I have seen recently is the Barret REC 7. Light(er) than most other rifles with out the heavy barrel, in 6.8 SPC for reach and punch, silencer ready, but I dislike SIR rails. In all honesty for any mission from 3 to 600 yards the perfection is 3 different rifles. However with many of us on a budget (not all of us I see from this thread) it is impossible. IMO, the perfect rifle is a heavy barrel 16 in carbine gas system and fixed front sight. (oh no not a middy  ) with a car rail system. The rifle is set up with a red dot, sling, light (with IR filter), IR laser, and cowitness BUIS everything but the BUIS and sling should be mounted with QD levers. Over all the package should come in at around 9-9.5LBS with a loaded mag. The shooters NVGs are helmet mounted. Now a scope can be kept with the shooter and thrown on in a hurry with a QD mount. You now have a rifle that will shoot 2 MOA or better in any conditions out to 600 yards if the shooter is up to it. It is handy enough for CQB work but still capable of fast reflexive shooting out to 300M offhand. This could easily be adapted to an 18inch barrel. The fact is a rifle of these specs can be put together for under $1800, or could be when the Cherrokee laser was available from AvengeUSA, and another $1800-$3000 for night vision. Silencers are nice and could easily be added if needed. |

If your bullet fragments, then you may not penetrate your target, and a .224" hole is better than no hole. I suspect you may be thinking of bullet expansion, which is a good thing, in some circumstances, but has no dependancy on barrel length. What expansion is dependant on is impact velocity, and bullet design. Some bullets are designed to expand at higher or lower velocities than others, and some not at all. All bullets (good ones), that are designed to expand on impact, are designed to retain the maximum mass weight, in order to preserve as much of the momentum as possible, so that the expanded bullet goes as far into whatever critter you are killing as possible. The only thing you shoot with a bullet that will 'fragment' are prarie dogs or other similar sized critters. |

Hmm, .22 diameter hole clean through the target, like stabbing it with a 1/4" wooden dowel??? Or a 3x6" temporary cavity filled with blood and destroyed tissue, not to mention the hydrostatic shock??? I'll take fragments for 100 Alex.

Huh? Military ball is designed to and works best when it does fragment. Fragmentation happens as the bullet yaws and breaks apart in the target, creating a large wound cavity. Fragmentation happens AFTER penetration. The dependency on barrel length is that a minimum velocity is required for fragmentation to reliably occur with ball ammo. The longer the barrel, the higher the muzzle velocity, so your effective fragmentation range is increased. That said, since mere civilians are not restricted to ball ammo, we can pick a heavier weight hollowpoint and fuggedaboutit. |

No AR can handle ALL applications, I don't think. I like to think "general purpose", short enough and light enough for mobility, long enough to reach out to 300 meters, "minute-of-man", as it were.....
For me, perfect is a 16 inch barrel. Red dot on top. Light up front. All I really need. |

You do realize that you can put a rifle length free float handguard onto any of the barrels you listed, and then throw a site on the top rail at the end, thus giving you your rifle length sites, right? |

The perfect AR is the one you are proficient enough with to put a round where you intend it to go, any time, every time, even in the dark of night.

I agree that a silenced AR is not worth the trouble, an SBR is an extra expense that most of us can't justify, that 'long range' would likely be < 50yds, and that compact size and a good fast optic is preferred. That's why I have this one.

How much does the Tavor weigh in at? Just curios. I've fired an FS2000 a couple of weeks ago and the trigger was like using a staple gun or something. Plus, it didn't really feel all that handy. Balance nice, yes. But bulky and sort of strange feeling to me. I suppose that changes with time. I'll throw my 2 cents in. The perfect AR always seems to be the one I don't have.   For example. I do a lot of shooting with irons. And I like LW. So I gots me a LW 16" upper. Carbine. Man is it sweet. But to be completely honest with you, I think for shooting irons, the rifle set up is the way to go. I should've just built up an A1 rifle and been done with it. I think a dissy with a lw profile barrel would be great. And a middy gas system. And a stock that balances it out nicely but isn't too long. I think an A1 stock LOOKS better but a bit shorter is better. Maybe the sully stock is the way to go. Come to think of it, probably the grail is the grail. But they're all pretty nice IMHO. And almost any configuration is pretty good for alot of things. As long as you stay away from the extremes. (such as a 7" pistol or a 24" heavy barreled rifle) |

The 18" model weighs 7.21lbs. Can't tell you about the trigger feel/pull... never handled one. I have heard that the FS2000 has a real heavy, creepy trigger. Don't know if that's an inherent bullpup flaw or a carryover from the FNC, which also had a lousy trigger. |
