Frequently Asked Questions

Can a 10-inch AR pistol be more powerful than a 16-inch AR rifle?

Yes, under certain conditions. This video demonstrates that a 10-inch AR pistol chambered in 7.62x39mm can achieve higher muzzle velocities than a 16-inch AR rifle firing different calibers, suggesting comparable or superior energy output from the shorter barrel.

Is 7.62x39mm a good caliber for short-barreled AR platforms?

The presenter argues that 7.62x39mm is an excellent choice for short-barreled ARs, including pistols. Ballistics data suggests it doesn't require a long barrel to achieve significant velocity and energy, making it a practical and cost-effective option.

How does 7.62x39mm compare to .300 Blackout for AR pistols?

The video suggests that 7.62x39mm is a more economical choice per round compared to .300 Blackout. It also implies that 7.62x39mm can deliver comparable or better energy from short barrels, making it a strong contender for AR pistol builds.

What were the muzzle velocities recorded in the AR pistol vs. rifle test?

The 10-inch AR pistol with 123-grain 7.62x39mm averaged around 659 m/s. The 16-inch AR rifle with 55-grain PMC eXtact averaged 896 m/s, and with 62-grain Mil-Surp green tips averaged approximately 907 m/s.
