The OCL OPS/AE Midway Adapter – Raw Heat Treated is a suppressor adapter built for rifles where barrel real estate is tight. If you've got a short-barreled platform or a handguard that runs close to the muzzle, this Otter Creek Labs adapter splits the difference between full-length solutions and minimal-footprint designs. You get the suppressor mounting capability you need without adding unnecessary length to your setup or requiring a complete barrel replacement.

The Midway adapter is engineered for shooters running short, crowned barrels where standard over-the-barrel (OTB) adapters won't work because there simply isn't enough room, yet a pin-and-weld solution feels like overkill. This adapter threads directly onto your barrel, keeping your overall package compact while maintaining the interface you need for your suppressor system. The raw heat-treated finish means it's ready to weather hard use and integrate seamlessly into your rifle's existing aesthetic.

Otter Creek Labs designed this adapter to serve a specific niche: rifles with tight geometry where 1.45 inches of exposed barrel is all you've got to work with. If your barrel shoulder to muzzle crown measures that tight, and your barrel OD is .75 inch or smaller, this adapter is your path forward. It threads on 1/2×28 to match the most common rifle muzzle pitch, making it a straightforward bolt-on for compatible setups.

Frequently Asked Questions

What barrels will the OCL Midway Adapter fit?

Your barrel needs at least 1.45 inches of exposed length measured from the barrel shoulder to the crown, a maximum outer diameter of .75 inch, and 1/2×28 threads. If your setup meets all three parameters, you're good to go.

When should I use the Midway Adapter instead of other Otter Creek Labs solutions?

The Midway is the middle ground: it requires less exposed barrel than the OTB (over-the-barrel) series but doesn't add the full length of a PTB (pin-and-weld) solution. If you don't have enough barrel for OTB but want to avoid permanently affixing a longer adapter, Midway is your answer.

Does the adapter come threaded and ready to install?

The adapter is machined with 1/2×28 threads and ready for installation on a compatible barrel. No additional gunsmithing is required if your barrel meets the specifications.

What suppressor systems work with this adapter?

Any suppressor with a 1/2×28 female mount will thread onto the Midway adapter. Check your suppressor's specifications to confirm the thread pitch.
