This video explores the performance of an extreme 36-inch barrel AR-15 compared to a standard 16-inch. Despite its length, the custom rifle reliably cycles and demonstrates increased velocity (3,284 fps vs 2,923 fps with 55gr ammo). Accuracy testing showed it could still hit targets, though handling was challenging due to the front-heavy design.

Quick Summary

A 36-inch barrel AR-15 significantly increases projectile velocity compared to a 16-inch barrel, reaching 3,284 fps versus 2,923 fps with 55gr Underwood ammo. Despite handling challenges due to its front-heavy design, the long-barreled rifle cycled reliably and could still hit targets at 100 yards.

Frequently Asked Questions

What is the velocity difference between a 16-inch and a 36-inch barrel AR-15?

Using Underwood 55gr hunting ammo, the 16-inch barrel AR-15 achieved 2,923 fps, while the 36-inch barrel AR-15 significantly increased velocity to 3,284 fps, demonstrating the impact of barrel length on projectile speed.

Does a 36-inch barrel AR-15 function reliably?

Yes, the custom 36-inch barrel AR-15 tested in the video functioned reliably. It successfully cycled through a 20-round magazine rapidly without any malfunctions, despite its unusual length.

How does the extreme length of a 36-inch barrel AR-15 affect accuracy?

The 36-inch barrel AR-15 is difficult to balance due to its front-heavy nature, which can impact accuracy. However, it remained capable of hitting targets at 25, 50, and 100 yards during testing.

Can a 36-inch barrel AR-15 penetrate a vehicle?
