Otter Creek Labs 1/2x28 Midway Adapter - Raw Heat Treated Finish

Otter Creek Labs 1/2x28 Midway Adapter - Raw Heat Treated Finish

When a full over-the-barrel setup is too demanding and a standard pass-through mount adds more length than you want, the Midway Adapter steps in as the perfect balance point—delivering compact performance without compromise.

Designed for shooters working with limited barrel exposure, the Midway Adapter requires only 1.45 inches of exposed barrel measured from the shoulder, making it one of the most versatile suppressor mounting solutions available. It bridges the gap between OTB and PTB systems, offering a clean, efficient mounting interface that preserves handling while maintaining suppressor compatibility.

Engineered for reliability and precision, this adapter is ideal for builders who want a low-profile, length-conscious suppressor setup without sacrificing stability or performance. Whether you're optimizing a compact AR-15 build or working within tight barrel constraints, the Midway Adapter gives you a practical, no-nonsense way to get the job done right.

Balanced “Midway” Design
Sits perfectly between over-the-barrel and pass-through systems, offering a smart middle-ground solution for optimized rifle length and suppressor mounting flexibility.

Minimal Barrel Requirement
Only 1.45 inches of exposed barrel needed from the shoulder, making it ideal for tighter or partially exposed barrel setups.

Compact Length Optimization
Designed to avoid the added bulk of PTB systems while providing more compatibility than full OTB configurations.

Versatile Compatibility
Works with barrels up to .75” outer diameter and standard 1/2x28 threaded AR-15 platforms.

Streamlined Suppressor Integration
Provides a stable, reliable mounting interface without unnecessary system complexity.
