Mount Compatibility Guide
Every LPM centerfire silencer (Anthem, Mach, Torch, DUTY, and COMP) uses the industry-standard 1.375"-24 rear thread, often called HUB. You can mount it two ways:
- Direct thread: a Rearden Ti Direct Thread Adapter screws into the silencer and onto your barrel. Lightest and shortest. Every direct thread LPM silencer ships with one.
- Quick detach (QD): a Rearden Atlas GEN 2 screws into the silencer, then threads onto a .900"-24 muzzle device on each rifle. Move one silencer between hosts in seconds.
Silencers
| Silencer | Rear thread | Direct thread | QD |
|---|---|---|---|
| Anthem, Mach, Torch, DUTY, COMP | 1.375"-24 HUB | Rearden Ti DTA, 1/2-28 or 5/8-24 | Rearden Atlas GEN 2 + any .900"-24 device below |
| Spark (.22 rimfire) | 1/2-28 direct | Threads straight onto your barrel | Not available |
The Atlas GEN 2 also fits any other brand's silencer with 1.375"-24 HUB or Bravo rear threads.
Muzzle devices for the Atlas (and other .900"-24 mounts)
| Device | Type | Barrel threads | Bore | Notes |
|---|---|---|---|---|
| Eclipse | Flash hider | 1/2-28, 5/8-24 | .30 cal | 1.7". Doubles as a sacrificial blast baffle |
| Eclipse-L | Flash hider | 1/2-28, 5/8-24 | .30 cal | 2.1". More flash reduction. Not compatible with Q silencers. Too short to pin and weld on 14.5" |
| Eclipse 13.7" Pin and Weld | Flash hider | 1/2-28, 5/8-24 | .30 cal | Takes 13.7" to 16.1". 3/32" pin. Not compatible with Q silencers |
| Eclipse 14.5" Pin and Weld | Flash hider | 1/2-28, 5/8-24 | .30 cal | Takes 14.5" to 16.1". 3/32" pin |
| Liberty Bell | Muzzle brake | 1/2-28, 5/8-24 | .30 cal | 1.7". Minimal concussion |
| Baby Bell | Muzzle brake | 1/2-28, 5/8-24 | .395" (9mm and smaller) | 1.1" |
Our devices also fit the Q Plan-B mount. And the Atlas accepts Q Cherry Bomb and other Plan-B compatible devices.
Every LPM device has 360-degree ports, so no timing shims are needed. If you time one for looks, use quality shims, never crush washers.
Adapters and protectors
| Part | What it does |
|---|---|
| 1/2-28 to 5/8-24 Thread Adapter | Runs 5/8-24 muzzle devices and silencers on a 1/2-28 barrel. Adds .19" |
| Thread Protector .900"-24 | Covers the threads and taper of LPM, Rearden, and Q muzzle devices when the silencer is off |
Front end caps and the MBEC
| Part | Fits |
|---|---|
| Standard .30 cal and 6.5mm front end caps | Anthem, Mach, Torch 5.56/6mm, and DUTY 5.56. 1"-24 threads, not compatible with other brands |
| MBEC (Muzzle Brake End Cap) | LPM, Dead Air, and OCL Infinity thread patterns. The LPM pattern fits every LPM centerfire silencer except the Torch 7.62. The MBEC has a .30 cal bore, so on .375 silencers use it only with .30 cal or smaller bullets |
The Torch 7.62 has a fixed two-stage end cap. It does not accept front end caps or the MBEC.
Install torque specs are in our torque guide and the LPM Master Installation Manual. Always confirm alignment with a bore alignment rod before firing.
