Rearden Atlas / 13/16 Muzzle Device Wrench

The Rearden Atlas / 13/16" Muzzle Device Wrench is the ultimate all-in-one solution for builders and suppressor users who demand durability, precision, and versatility at the bench or in the field.

Designed to fit both Gen 1 and Gen 2 Rearden Atlas suppressor mounts, this wrench also supports muzzle devices with 13/16" wrench flats, including those from Rearden, Liberty Precision Machine, KAK, and others.

Dual Suppressor mount sizes; 1-1/4" and 1-1/16" make it compatible with a wide range of mounts (excluding Atlas XL).

Crafted from .190" thick 4130 chromoly steel, this tool resists bending under high torque. The finish is sandblasted, cold blued with Brownells Oxpho-Blue, and treated with mineral oil for rust and corrosion resistance.

Whether you’re going for maximum torque or quick adjustments, it features:

• 1/2" square drive for use with torque wrenches or breaker bars
• Dual wrench interfaces for a balance of speed and strength

Key Features:

• Fits Rearden Atlas Gen 1 & Gen 2 suppressor mounts
• Compatible with muzzle devices featuring 13/16" flats
• May fit other mounts with 1-1/4" or 1-1/16" wrench flats
• .190" thick 4130 chromoly steel – tough, bend-resistant

Care Tip: For best long-term performance, periodically rub down the wrench with your preferred gun oil to maintain rust resistance.

Whether you're installing, removing, or tuning your setup, the Rearden Atlas / 13/16 Wrench delivers reliable torque and long-term durability—all in one tool.

I have 7 Atlas mounts between gen 1 and gen 2, a mix of raw, nitride, and DLC coated. This mount fits perfectly on 6 of them, it's a bit tight on one of the Nitrided versions, so PLEASE NOTE: Due to varying tolerances and coating thicknesses, this wrench may be tight on some suppressor mounts and muzzle devices. I have tried to make this fit as snugly as possible to avoid any potential rounding of mounts or muzzle devices because I also hate when that happens to me when I'm trying to use an off the shelf wrench. The tight fitment is a byproduct of trying to keep that interface fitment as tight as is reasonable.
