Ported Barrel VS Compensator??

Published on November 23, 2024
Duration: 12:59

This video compares the velocity loss between ported barrels and compensators on various firearms, as well as the impact of barrel length. The presenter, Mr. Madness, uses a Garmin X1 Pro chronograph to measure the feet per second of 115-grain 9mm Blazer ammunition fired from a CZ Checkmate (5-inch barrel with comp), CZ Shadow 2 (4.9-inch ported barrel), CZ Shadow 2 (4.9-inch factory barrel), CZ PCR (4.9-inch factory barrel), and Glock 43 (3-inch barrel). The tests indicate a slight velocity loss with ported barrels compared to factory barrels and a more noticeable decrease with shorter barrel lengths.

Quick Summary

A ported barrel typically causes a slight velocity loss compared to a non-ported barrel due to gas escaping through ports. Shorter barrels also significantly reduce projectile velocity. Tests show minimal velocity difference between compensators and ported barrels, but barrel length has a more pronounced effect.

Frequently Asked Questions

Does a ported barrel reduce firearm velocity?

Yes, a ported barrel typically results in a slight reduction in projectile velocity compared to a non-ported barrel of the same length. This is due to some of the expanding gases escaping through the ports instead of continuing to propel the bullet down the barrel.

How does barrel length affect 9mm velocity?

Shorter barrels lead to lower projectile velocity because the bullet has less time and distance to accelerate. For example, a 3-inch barrel will produce significantly less velocity than a 5-inch barrel with the same ammunition.

What is the difference in velocity between a compensator and a ported barrel?

While both affect gas management, a compensator is primarily designed to redirect gas upwards to reduce muzzle rise, whereas ports are designed for recoil reduction. The velocity difference between a firearm with a compensator versus one with a ported barrel of similar design is often minimal, as observed in this test.

What equipment was used to measure firearm velocity in this test?

The presenter utilized a Garmin X1 Pro chronograph to accurately measure the feet per second of the 115-grain 9mm Blazer ammunition fired from various firearms with different barrel configurations and lengths.
