Infinite Product Solutions M15 x 1 – 5/8-24 Thread Adapter Review

What Makes Infinite Product Solutions M15 x 1 – 5/8-24 Thread Adapter Stand Out?

The Infinite Product Solutions M15 x 1 – 5/8-24 Thread Adapter is a seemingly simple, yet incredibly important piece of kit for owners of certain H&K rifles and older PTR variants. This adapter allows you to convert your firearm’s existing M15 x 1 threaded barrel to the more common 5/8-24 thread pattern. This opens up a world of possibilities for attaching muzzle devices, suppressors, and other accessories that might otherwise be incompatible.

I was driven to this product out of necessity. I recently acquired a beautiful, albeit older, H&K 91. I quickly realized that its metric M15 x 1 threads presented a significant hurdle in mounting any of my preferred 5/8-24 muzzle devices.

Upon unboxing, the adapter impressed me with its solid construction. The stainless steel felt robust and the machining appeared precise. Its compact size and clean lines suggested it would integrate seamlessly with the rifle.

I considered a few other options, including having the barrel re-threaded. This seemed like a costly and irreversible modification, which is why I favored the Infinite Product Solutions M15 x 1 – 5/8-24 Thread Adapter. Another option was a different thread adapter from an off-brand name, but I was willing to pay a little extra for the quality and peace of mind from Infinite Product Solutions.

My first impression was a sense of relief and anticipation. The adapter promised a straightforward solution to my threading dilemma. I was eager to test its fit, function, and impact on the rifle’s performance.
