Otter Creek Arms Llc OCL101 ZRO DTA 1/2x28

Overview

The Otter Creek Labs ZRO DTA is a second-generation direct thread adapter designed by Rearden MFG to bridge 1/2x28 threaded barrels with industry-standard 1.375x24 suppressors and muzzle devices. Engineered to add minimal length and weight to the system, the Gen 2 features extended wrench flats in the rear and an opened-up interior that increases internal volume while shedding 0.3 ounces compared to the first generation. Manufactured from 6Al-4V grade 5 titanium with a durable black PVD coating, the adapter weighs a mere 0.9 ounces. Its precision construction ensures a secure fit, eliminating wobble and maintaining repeatable point-of-aim retention across multiple mounting cycles for short-barreled rifles, pistol-caliber carbines, and precision setups.
