What's it DO? Linear Comp/ Blast Device

Published on May 2, 2021
Duration: 11:00

This video debunks common myths surrounding linear compensators and blast devices, clarifying their actual function. The host explains they don't significantly reduce recoil or increase back pressure, and their sound redirection is minimal. The primary benefit is coalescing the pressure wave forward of the muzzle, making the blast less disruptive to others.

Quick Summary

The primary function of a linear compensator is to direct muzzle blast and gas pressure forward, coalescing the pressure wave further downrange. This makes the firing impulse less disruptive to teammates or bystanders, rather than significantly reducing recoil or suppressing sound.

Frequently Asked Questions

What is the primary function of a linear compensator?

A linear compensator's main purpose is to direct muzzle blast and gas pressure forward, away from the shooter and nearby individuals. It coalesces the pressure wave further downrange, making the firing impulse less disruptive to teammates or bystanders.

Do linear compensators reduce recoil significantly?

No, linear compensators offer negligible recoil reduction compared to a full suppressor. While they theoretically sequester gas, the effect on felt recoil is minimal and not their primary design goal.

Do linear compensators increase back pressure?

Linear compensators do not significantly increase back pressure. Only devices like suppressors that increase dwell time affect cycling. Linear comps have too little internal volume to noticeably alter the gas system's operation.

How much do linear compensators redirect sound?

Testing indicates linear compensators provide only a minor sound reduction, around 3dB outdoors at the shooter's ear. This is insufficient for hearing protection and not their intended purpose.
