The 24" barrel would be 17.4 lbs lighter than what I got used to humping. How is that relevant? eta- did you seriously not follow that? Nah, but the 24" barrel can hit plates off hand at 400 yards. Every 4" of additional barrel doubles an ARs accuracy, stopping power, and lethality. You should see a 28" |

Has anyone compared the toeloading characteristics of a A4 versus a M4? I don't believe this important quality has been discussed, yet.

shouldn't engagement distances dictate the barrel length used? a 14.5" M4 and a 20 M16A4 are pretty much equally accurate over 300m but its the effectiveness of the 5.56mm round thats reduced with the lower velocities.
i read AARs of operations in Iraq where it was stated that most engagements were under 100m, with many at 25m. at these ranges the M4 works fine. however with operations in Afghanistan, engagements moved to much greater distances due to the terrain. it seems ass-backward to move to a shorter barrel rifle as engagements distances increase, when your primary round is so dependent on velocity for its effectiveness. this time of moving to a shorter barrel + longer ranges also seems to be when more complaints about the 5.56mm 'stopping power' at long range started coming out |

Velocity by itself doesn't mean much.
You either make enough to frag or you don't. A longer barrel increases the range at which 5.56mm can be expected to frag reliably. At 100m, a 14.5" bbl makes plenty of velocity for explosive fragmentation. At 300m, I would want something longer. |

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.

You must shoot with children or some really shitty shooters or just trying to convince yourself you made the right choice with your 20" AR. Perhaps the point he was trying to make is that when using open sights, the 20" AR will have the advantage, because the front sight is further out there, closer to the target. |

My 20" heavy barrel is a varmint killer, don't like to carry it very far though.

Higher velocity gives the bullet more RPMs for better stabilization, so a 20" 1:9 might stabilize a heavier bullet whereas a 14.5" 1:9 might not.

I skipped the middle pages, but have we discussed that 5.56 is too flaccid and weak to reach the end of a 10.5" barrel yet?

I like my barrels as short as possible for reliable operation. That way, at longer ranges, I can use it as an indirect fire weapon to deny the enemy defilade.

I think Suppressors, and their increasing popularity and availability are part of it. Put a can on a 20" rifle, now you got a 26" rifle with an extra pound or so out on the end. Drop your barrel down and you can get a suppressed 14.5" carbine with about the same overall length, but the benefit of having a suppressor. If your 14.5" rifle isn't "doing the job", then maybe you just need a different tool. Everyone wants to think there's 1 rifle to do it all, but you run into "jack of all trades, master of nothing". And that's where other calibers come in as well, you can get shorter suppressed packages with a better round, but then you run into supply chain issues...

The reason we have 5.56 NATO and not .222 Remington is because of an arbitrary 500m steel helmet perforation requirement set by the 30 cal nazi's at Army Ordnance. They were trying to kill the SCHV rifle concept by moving the goal posts, but failed to do so.
Even 11.5" carbines exceed the capability of most soldiers at 300m. Since the "cool kids" have been stacking bodies with 5.56 Colt Commando's since the 1960's, they never got the memo that they needed 20" guns. It isn't about looks, but performance. 20" is not needed to get it done. Even the 18" SPR's have been set aside in favor of Block II SOPMOD with Mk.262 or other loads. If a carbine has already been proving itself to be more than adequate for its intended use, why would I ever want a 20" gun? Keep in mind that the minority in Army Ordnance who were proponents of the SCHV wanted 3400fps mv. |
