Which LPM Muzzle Devices Fit Your Mount?

If you run a QD silencer, your muzzle device is the foundation. Here is what fits what.

The short version

Every LPM flash hider and brake has a .900"-24 outer thread, the same pattern used by the Q Plan-B and the Rearden Atlas. If your mount takes Plan-B devices, ours fit.

Pick by job

• Flash hider, general use: Eclipse (1.7"). It also serves as a sacrificial blast baffle, which protects your silencer's first baffle.
• Maximum flash reduction: Eclipse-L (2.1"). Not compatible with Q silencers; it bottoms out on their blast baffle.
• Recoil reduction: Liberty Bell (1.7", .30 cal bore) or Baby Bell (1.1", .395" bore for 9mm and smaller).
• Short barrel, need 16": Eclipse 13.7" or Eclipse 14.5" Pin and Weld. The 13.7" version carries the same Q silencer warning as the Eclipse-L. See our guide: 13.7" vs 14.5" Pin and Weld.

Thread pitch

Every device comes in 1/2-28 or 5/8-24. Running a 5/8-24 device on a 1/2-28 barrel? Use our 1/2-28 to 5/8-24 Thread Adapter. Not sure which pitch you have? Read our thread pitch guide.

When the silencer is off

A .900"-24 Thread Protector covers the taper and threads on any LPM, Rearden, or Q device.

See the full chart on our Mount Compatibility Guide. For the QD mount itself, see the Rearden Atlas GEN 2, or browse all muzzle devices.
