A flash hider and a muzzle brake do different jobs. A flash hider cuts the flash you see at the muzzle. A brake cuts recoil. With a silencer on, both also serve as the mount it locks onto. Here is how our four devices compare.
Quick answer
- Eclipse flash hider: you shoot suppressed most of the time, or you want less flash when the silencer is off.
- Liberty Bell brake: you shoot without the silencer often and want less recoil, or you run a titanium Mach on a barrel shorter than 14.5".
Side by side
| Eclipse | Eclipse-L | Liberty Bell | Baby Bell | |
|---|---|---|---|---|
| Type | Flash hider | Flash hider | Muzzle brake | Muzzle brake |
| Length | 1.7" | 2.1" | 1.7" | 1.1" |
| Weight | 1.6 to 2.0 oz | 1.7 to 2.1 oz | 1.6 to 2.0 oz | 1.3 to 1.6 oz |
| Bore | .30 caliber | .30 caliber | .30 caliber | .395", for 9mm or smaller bullets |
| Thread pitches | 1/2-28, 5/8-24 | 1/2-28, 5/8-24 | 1/2-28, 5/8-24 | 1/2-28, 5/8-24 |
| Price | $79 | $89 | $79 | $59 |
All four fit common .900"-24 silencer mounts like the Q Plan-B and Rearden Atlas. All are machined from 17-4 PH stainless, heat treated to H900, with every critical alignment feature cut in one setup. Each has a 13/16" rear hex and 360 degree port orientation, so no shims are needed.
Eclipse flash hiders
The Eclipse gives substantial flash reduction over a factory flash hider. It is also designed to serve as a sacrificial blast baffle: it takes the first blast of hot gas so your silencer's own blast baffle does not have to. The longer Eclipse-L reduces flash even more than the standard Eclipse. Two cautions on the Eclipse-L: it is not compatible with Q silencers, and it is too short to pin and weld on a 14.5" barrel.

Liberty Bell and Baby Bell brakes
The Liberty Bell gives a substantial improvement in recoil reduction over a factory device, with minimal concussion. The Baby Bell is our shortest device at 1.1". Its .395" bore is sized for 9mm or smaller bullets, like 5.56. Do not use it with .30 caliber or larger.
How to choose
A brake sends gas out the sides. That cuts recoil, but with the silencer off it makes each shot louder and harsher for anyone beside you. A flash hider keeps the blast more forward and hides flash. With the silencer on, either works as the mount, and the silencer handles the gas. If you run a titanium Mach on a barrel shorter than 14.5", we recommend a brake.
Running a muzzle device with another maker's silencer? Some makers void their warranty when you use other brands' devices, so check first. Always confirm alignment before you shoot. See our Mount Compatibility Guide and Direct Thread vs. Atlas QD. Shop all muzzle devices.
