What is the best length barrel for an AR 15?
20″ barrels provide the most consistent performance across the widest variety of loadings. There are plenty of modern specialized loads “optimized” for use in a 16″ barrel, but the 20″ length will still do things better. Aside from the benefits of velocity, the long 20″ barrel gives a balance benefit to marksmen.
What is the best barrel length for 556?
The best barrel length for a 5.56 caliber rifle is in the 18-20 inch (45.72-50.8 cm) range. While a longer barrel offers increased bullet velocity, this benefit is offset by the greater weight of longer barrels, which reduces handling in close-quarters environments, like inside buildings.
What is the overall length of an AR-15 with a 10.5 barrel?
The AR-556 has a barrel length of just 10.5 inches and an overall length of 25.3 to 27.9 inches.
What barrel length does US military use?
One of the biggest differences between the M4 and the M16A4 is the barrel length: 14.5 inches versus 20 inches, respectively. The M16A4’s longer barrel allowed for a higher muzzle velocity and a longer effective range; conversely the shorter M4 barrel limited its performance in both categories.

Which is better a 16 inch barrel or a 14.5 inch barrel?
Pinning and welding a 14.5 inch barrel to get to minimum length get’s you the ability to mount a bayonet, and slightly shorter than a 16 inch barrel with standard flash hider. The 14.5 barrel costs you some muzzle velocity too. You should go with 16 inch barrel. I’ve got a single 14.5 pinned upper, because that is what came with a Colt M4 I have.
How big is the barrel on an AR 15?
Currently shooting 9mm and 45ACP handguns and the AR 15 holds a very strong attraction. In doing my research it seems the 5.56 guns are predominantly 16″ barrels and that is probably the direction I am going.
What’s the difference between AR 15 and 5.56mm?
A 30-shot string of Hornady 5.56mm 75 grain TAP T2 chronographed over an Oehler 35-P chronograph from a Noveske 18” SPR barreled AR-15 had an average muzzle velocity of 2779 FPS; for a difference in muzzle velocity of 44 FPS. “Foot/pounds” of energy means next to nothing for any meaningful exterior ballistics or terminal ballistics comparisons.
What’s the muzzle velocity of a Hornady AR 15?
A 30-shot string of Hornady 5.56mm 75 grain TAP T2 chronographed over an Oehler 35-P chronograph from a 16” Novekse Recon barreled AR-15 had an average muzzle velocity of 2735 FPS.
