Being Specific. When talking about the baby AR I’m not talking about 9mm or 22 LR guns, but ARs that fire the standard 5.56/22 rounds with the shortest, most common barrels out there. As far as I can see the 7.5 inch AR is the shortest you can commonly find.

Does barrel length affect accuracy AR-15?

Barrel length has little to do with accuracy. If anything, longer barrels reduce accuracy potential.

Is a shorter barrel more accurate?

Longer barrels are not more accurate. If anything, it’s quite the opposite. Shorter, stiffer barrels tend to vibrate more consistently and are probably more accurate on average. However, quality of barrel and bedding are far more important, so we will leave accuracy out of this discussion.

How far will a 10.5 inch AR shoot?

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 is the twist rate of an AR-15 barrel?

For example, the barrel of the very first AR-15 made by Armalite had a twist rate of 1:14, which means that the rifling took 14 inches to complete a full rotation. This rate was marginal at best, since bullets became unstable during testing in colder, high-pressure climates. A faster rotation allows for more bullet stability.
