REARDEN PNW FH .375 5/8X24 NITRIDE

The Rearden PNW flash hider in .375 bore with 5/8x24 thread pitch is a purpose-built muzzle device for shooters running modern platform rifles that demand both flash suppression and reliability. Built on Rearden's proven design, this flash hider fits seamlessly into the Atlas, Atlas XL, and Plan B ecosystems—if you're already deep in one of those systems, this integrates without extra adapters or fuss. The nitride finish handles the punishment of repeated shooting cycles and field conditions without rust creep or finish breakdown.

Flash hiders matter most when you care about sight picture and situational awareness. Whether you're training at an indoor range, running night courses, or hunting in low-light conditions, controlling muzzle flash keeps your eyes adjusted to the target and eliminates that bloom that can wash out your optic view. This one does exactly what it's designed for—nothing more, nothing less—and the 5/8x24 thread pitch is the modern standard for .375-bore rifles, so compatibility is straightforward if your barrel is cut for that dimension.

Rearden's nitride coating is the workhorse finish: tough, corrosion-resistant, and low-maintenance. It won't look showroom-new after a season in the field, but it'll still function reliably when it matters. If you're building or upgrading a .375-bore rifle and want a flash hider that plays nice with Atlas-platform suppressors and brakes, this is the plug-and-play choice.

Frequently Asked Questions

Will this work with my suppressor or muzzle brake?

The Rearden PNW flash hider is compatible with the Atlas, Atlas XL, and Plan B platforms. If your suppressor or brake is part of one of those systems, integration is straightforward. If you're not sure which platform your other components use, verify before ordering.

What thread pitch do I need?

This flash hider has a 5/8x24 thread pitch. Your barrel must be cut for 5/8x24 threading. If your rifle uses a different thread pitch (like 1/2x28 or 9/16x24), this won't fit without an adapter.

Is the nitride finish enough protection for regular use?

Nitride is a durable, corrosion-resistant finish designed for field conditions. It handles shooting, weather, and handling well. Like any finish, regular cleaning after wet conditions keeps it in top shape, but nitride is low-maintenance compared to blued or parkerized options.

Does this come with shims or crushers for timing?

The product record does not specify whether shims or crush-wash components are included. Contact customer service to confirm what's in the box before installation.
