Infinite Product Solutions M26 x 1.5 LH – 5/8-24 Thread Adapter Review

What Makes Infinite Product Solutions M26 x 1.5 LH – 5/8-24 Thread Adapter Stand Out?

The Infinite Product Solutions M26 x 1.5 LH – 5/8-24 Thread Adapter is a seemingly simple piece of steel, but it unlocks a world of possibilities for owners of Zastava ZPAP92 and M85 pistols. This adapter allows you to convert the less common M26 x 1.5 LH thread pattern to the ubiquitous 5/8-24 thread, opening the door to a vast array of muzzle devices and accessories.

I recently acquired a ZPAP92 and quickly realized the limitations of its unique threading when it came to attaching my preferred muzzle brake. The challenge was finding a solution that wouldn’t compromise the firearm’s reliability or aesthetics. The Infinite Product Solutions M26 x 1.5 LH – 5/8-24 Thread Adapter promised to be that answer.

Upon unboxing, the adapter felt solid and well-made, a testament to its steel construction. Its black finish appeared durable and blended seamlessly with the ZPAP92’s existing components. Picking it up, the weight of 3.2 oz felt substantial enough to inspire confidence.

I considered a few other adapters, including some from lesser-known brands on various online marketplaces. Ultimately, I chose the Infinite Product Solutions adapter due to their reputation for quality and precision machining. I was excited to finally expand my options for muzzle devices on the ZPAP92, anticipating improved recoil management and muzzle control.

First Use Experience

My first experience with the Infinite Product Solutions M26 x 1.5 LH – 5/8-24 Thread Adapter was at my local outdoor shooting range. The weather was clear and dry, providing ideal conditions for testing. Installation was surprisingly easy, thanks to the included detent pin slots.

The adapter threaded smoothly onto the ZPAP92’s barrel, and my 5/8-24 muzzle brake secured tightly without any wobble.

Extended Use & Reliability

After several weeks of consistent use, the Infinite Product Solutions M26 x 1.5 LH – 5/8-24 Thread Adapter continues to perform flawlessly. I’ve put several hundred rounds through the ZPAP92 with the adapter installed and have observed no loosening or shift in point of impact. The black steel construction shows no signs of wear or corrosion.

Cleaning is straightforward. A quick wipe-down with a solvent-soaked cloth removes any carbon buildup. In comparison to some cheaper adapters I’ve used in the past, this one definitely inspires more confidence in its longevity and reliability. This adapter has exceeded my initial expectations.
