Description
Liberty Precision Machine built the Eclipse to solve a problem every suppressor owner knows well: most muzzle-mount adapters look great with a can hanging off them and downright ugly when the can comes off. The Eclipse flips that around. It's a genuinely good-looking flash hider on its own, and when you're ready to run suppressed it mates right up to common .900"-24 mounts like the Rearden Atlas and the Q Plan-B. That dual-purpose design is what makes it stand out in a crowded muzzle device market.
What Makes the Eclipse Flash Hider Tick
Every critical alignment feature is machined in a single setup, which is the kind of detail that matters when you're bolting a can in front of a bullet. The 360-degree port design means there's no timing, no shims, and no fussing to get the ports oriented. A 13/16" rear hex lets you grab it with a wrench for quick install and removal. The .30 caliber bore keeps it versatile across a range of calibers, from .223/5.56 builds on up through .308 and 7.62 rifles.
Built to Take a Beating
The Eclipse is CNC-machined from 17-4 PH stainless steel and heat treated to H900, so it holds up to the heat and pressure that come with life right at the muzzle. It also acts as a sacrificial blast baffle, taking some of the abuse that would otherwise wear on your silencer and helping stretch out the service life of your can. Folks who've run these consistently call out the sharp machining, tight lockup on the mount, and concentricity that checks out with an alignment rod.
Sizing and Fitment Notes on the Eclipse
This is the 1.70" version with 1/2×28 threading, sized to work as a pin-and-weld option on a 16" barrel. If you're chasing a shorter barrel setup, LPM offers longer variants for 14.5" and 13.7" builds. Worth knowing up front: this particular length is not intended for a 14.5" pin and weld, and it isn't the right pick for Q silencers specifically, so match the length to your barrel and your can before you order.

Frequently Asked Questions
What suppressor mounts does the Eclipse Flash Hider work with?
The Eclipse is designed around common .900"-24 suppressor mounts, including the Rearden Atlas and the Q Plan-B. It also pairs naturally with LPM's own Anthem-S suppressor. It's a HUB-style setup, so any can running a compatible .900"-24 adapter should thread right up.
Does the Eclipse Flash Hider need to be timed or shimmed?
No. The 360-degree port design means there's no timing to worry about, so you won't need shims or crush washers to index the ports. Just thread it on with a wrench on the 13/16" rear hex and you're good, though you should always confirm alignment before running a suppressor over it.
What barrel length is this 1.70" Eclipse sized for?
This length is intended for a pin-and-weld setup on a 16" barrel or as a standard thread-on muzzle device. It is not sized for a 14.5" pin and weld, so if you're running a shorter barrel you'll want one of the longer Eclipse variants LPM offers for 14.5" and 13.7" builds.
Why does the finish look a little uneven on some Eclipse Flash Hiders?
Natural variation in the heat-treated finish is normal and purely cosmetic. It comes from the H900 heat treat process and does not affect the strength, durability, or performance of the muzzle device. Every unit is machined and treated the same way regardless of slight color differences.
