Linear Compensators — How They Work & Advantages vs. Brakes

In this interesting video, Brownells Gun Tech Caleb Savant covers the topic of linear compensators, aka “blast diffusers” or “linear blast devices”. These are quite different in function from a typical muzzle brake and they are NOT a sound suppressor. Unlike a traditional muzzle brake, a linear compensator directs the muzzle blast forward, AWAY from the shooter. This is not only good for the shooter but also for folks next to the shooter, either at the range or in a CQB law enforcement or military situation.

A “Linear Compensator”, also known as “blast diffuser”, my look similar to a muzzle brake. But it works differently. A typical muzzle brake shoots blast out the side, and can be pretty annoying for someone positioned next to the shooter. By contract, the Linear Compensator direct blast force more forward. This helps reduce perceived recoil, and importantly doesn’t send hot gasses left and ring to nearby shooters or observes. Muzzle brake output can be very annoying. This Editor once was shooting next to a .338 Lapua Magnum with a brake, just a couple feet away. With each .338 LM shot I could feel heat on arms/hands and actually feel the bones in my forearm vibrate.

Attachment Methods — Direct Thread Mounting vs. Quick-Attach Mounting
Linear compensators have become much more popular in recent years as AR-15 pistols and SBRs have proliferated. Some linear comps, such as popular models from Midwest Industries and the Troy Claymore, attach directly to the muzzle, just like a traditional flash hider or muzzle brake.

Other Linear Compensators are slip-on, quick-attach components that mount OVER another muzzle device. For example, the VG6 Precision CAGE Device (Concussion Altering Gas Expansion) attaches directly over one of their standard muzzle devices. Almost every company that makes a sound suppressor also offers a linear compensator, which typically attaches to the muzzle the same way as the silencer.
