Is a 16 inch barrel too long?
The 16” barrel is perfect because it’s not too long where you’re losing accuracy, but it’s not too short where you’re losing velocity effectiveness. For long-range targets, the longer the barrel the better. This is really the only case when velocity equals accuracy.
What is the muzzle velocity of an AR-15 round?
3,300 ft/s
| ArmaLite AR-15 | |
|---|---|
| Barrel length | 20 in (508 mm) |
| Cartridge | .223 Remington |
| Action | Gas-operated, rotating bolt |
| Muzzle velocity | 3,300 ft/s (1,006 m/s) |
What is the best barrel length for 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 range of an AR-15 with a 16 inch barrel?
For a standard 16” barrel shooting 223/5.56, the 50-yard zero is the flattest shooting and you just need to remember that last 200 yards you start to aim higher… and 300 yards, as long as you can see your target, won’t be impossible to hit with a red dot. For a 10.5 inch barrel, the 50 or 36-yard zero will be ideal.
What size barrel Do Navy Seals use?

Is a 16 inch barrel good for 223?
Handloading ammo with different powders and Bullets can compensate for this and a 16″ barrel can allow a higher velocity than with a Standard load. I’ve measured the muzzle velocity for a typical 5.56/223 round out of my 16″ AR-15 and it hits around 2750 fps. Out of my 20″ AR it is around 3000 fps.
How far can you shoot a 556 accurately?
Data Based Conclusions: Self-Defense: Like the Army says, the 5.56 is effective for self-defense well beyond 500 yards. Whether you can even consider a target to be a threat at that range, however, is another matter altogether. Hunting: The 5.56 consistently fails to deliver 1,000 ft lbs of energy beyond 100 yards.
