Otter Creek Labs OCL-701 OPS Past-the-Barrel Adapter

Otter Creek Labs OCL-701 Past-the-Barrel Adapter

The OCL-701 is a precision-engineered one-piece adapter designed to mount Ops Inc 12th Model, AEM5, and OCM5 suppressors to rifles where standard over-the-barrel adapters won't work.

Construction & Design

Material: H900 heat-treated 17-4 stainless steel provides exceptional durability and corrosion resistance.

Thread Pattern: 1/2x28 threads accommodate a wide range of modern rifle barrels.

Integrated Wrench Flats: Built-in wrench flats on the rear allow quick installation and removal with any adjustable crescent wrench—no special tools required.

When to Use This Adapter

The Past-the-Barrel design solves mounting challenges that standard adapters cannot:

• Barrels with an outside diameter larger than .75 inches
• Rifles with less than 2.95 inches of exposed barrel
• Compact or short-barreled rifle configurations

Important Considerations

System Length: This adapter adds 2.90 inches to your overall suppressor system length. Plan your setup accordingly.

Alignment Critical: Because the end cap sits significantly forward of the muzzle, always verify alignment with an alignment rod before firing. Imperfect barrel threads combined with a tight-tolerance suppressor bore can result in end cap strikes if not properly checked.

The OCL-701 delivers reliable performance for shooters who need a solution beyond conventional mounting options.
