Its purpose is to allow suppressors with the common 1.375×24 HUB mounting pattern to be directly threaded onto barrels with 1/2×28 threads, expanding the versatility of my existing investments.

I had been frustrated by the limitations of QD mounting systems on some of my AR-15 platforms, especially regarding weight and length. I wanted a more streamlined, direct-thread solution for a dedicated suppressed rifle. The Griffin Armament DT1375X24-1/2X28 Thread Adapter appeared to be the perfect solution.

I considered a few other options, including adapters from SilencerCo and Dead Air. I ultimately chose the Griffin Armament DT1375X24-1/2X28 Thread Adapter due to Griffin Armament’s reputation for precision and the readily available wrench flats for easy installation. The others seemed to prioritize quick detach features, which wasn’t my main focus. I wanted simple and bombproof.

Real-World Testing: Putting Griffin Armament DT1375X24-1/2X28 Thread Adapter to the Test

First Use Experience

I tested the Griffin Armament DT1375X24-1/2X28 Thread Adapter at my local outdoor shooting range. It was a typical summer day in Texas, hot and dusty. I mounted the adapter on a 5.56 AR-15 rifle, pairing it with my Griffin Armament Bushwhacker 36 suppressor.

Installation was straightforward. The wrench flats made tightening the adapter onto the barrel threads simple, and it mated perfectly to the suppressor. I experienced no issues with cross-threading or poor fitment. I ran about 200 rounds through the rifle that day.

After my initial testing I did experience some carbon buildup on the threads after firing suppressed for a bit. I would recommend having some sort of thread protecting grease or anti-seize compound to minimize that.

Extended Use & Reliability

After several months of regular use, the Griffin Armament DT1375X24-1/2X28 Thread Adapter continues to perform flawlessly. I’ve used it on multiple AR-15s with 1/2×28 threads, and each time, it provides a secure and reliable connection. There are no signs of loosening or degradation.

The nitride finish has held up exceptionally well, showing no scratches or wear despite frequent use and cleaning. I’ve also used it in some light rain with no issues. Cleaning is simple: a quick wipe down with a solvent and a brush removes any carbon buildup. This adapter requires very little maintenance.

The Griffin Armament DT1375X24-1/2X28 Thread Adapter has significantly outperformed my expectations compared to other adapters I’ve used in the past. The ease of installation, robust construction, and consistent performance make it a top-tier product. It has become an indispensable part of my suppressor setup.
