Weaver Thumb Nut SPR Optics 1 Inch Mount Set Review

The Weaver Thumb Nut SPR Optics 1 Inch Mount Set Made a Bold First Impression

The Weaver Thumb Nut SPR Optics 1 Inch Mount Set promises a streamlined, reliable optic mounting solution for AR-style rifles, focusing on ease of use and a secure, repeatable zero. I was immediately drawn to the thumb nut design, envisioning quicker optic swaps and adjustments in the field, a critical factor for adapting to varying shooting scenarios. The Weaver name carries a legacy, and I expected a level of quality to match.

My need arose from a desire to streamline my optic setup on my AR-15. I was tired of fumbling with tools to swap between a red dot for close-quarters training and a magnified scope for longer-range target practice. I had considered quick-detach (QD) mounts, but many seemed bulky or prone to loosening, and I needed something robust and reliable, without sacrificing speed.

Upon unboxing, the mount set felt solid and well-machined. The matte black finish was clean and even, and the thumb nuts felt substantial and easy to grip, even with gloves on. The design struck a good balance between being lightweight and sturdy. Compared to some bulkier, more complex QD mounts I’ve used, the Weaver Thumb Nut SPR Optics 1 Inch Mount Set presented a more streamlined and efficient profile.

I had also considered a LaRue Tactical QD mount, known for its robust clamping force, and a less expensive UTG Pro mount as budget alternatives. Ultimately, I chose the Weaver Thumb Nut SPR Optics 1 Inch Mount Set for its blend of a reputable brand name, the appealing thumb nut adjustment, and the promise of a return-to-zero capability, all at a reasonable price point. I was initially excited, hoping this would be the simple yet effective solution I had been searching for.

Real-World Testing: Putting Weaver Thumb Nut SPR Optics 1 Inch Mount Set to the Test

First Use Experience

My initial testing took place at my local outdoor shooting range, where I mounted a Leupold VX-Freedom 1.5-4x20mm scope onto my AR-15 chambered in 5.56 NATO. I focused on zeroing the scope and then removing and reattaching the mount several times to test the return-to-zero claim. The weather was clear, but the temperature was hovering around 40°F (4°C), so I wore gloves.

The thumb nuts made installation and removal remarkably simple, even with gloves. After initially zeroing the scope, removing and reattaching the mount resulted in only a minor shift in point of impact – less than 1 MOA. The ease of use was immediately apparent, and the mount felt secure throughout the initial testing phase.

One minor issue I noted was the thumb nuts, while easy to grip, required a consistent level of torque to achieve a truly secure fit. Over-tightening seemed possible, so finding the “sweet spot” took a little practice.

Extended Use & Reliability

After several months of use, the Weaver Thumb Nut SPR Optics 1 Inch Mount Set has proven to be a reliable and durable optic mounting solution. It has been used in multiple range sessions, a weekend hunting trip, and a carbine course in varied weather conditions. The mount has experienced temperatures ranging from 25°F (-4°C) to 90°F (32°C), and has been exposed to light rain and dusty conditions.

The mount has held up remarkably well, with no signs of loosening or shifting, even after hundreds of rounds fired. The matte black finish has shown some minor wear marks, primarily around the edges, but nothing significant. Cleaning has been easy – a simple wipe down with a lightly oiled cloth has been sufficient to remove any dirt or debris.

Compared to other mounts I’ve used, this Weaver mount outperforms cheaper alternatives in terms of durability and return-to-zero capability. While not as bombproof as some high-end QD mounts, the simplicity and robust design provide excellent reliability for the price. It certainly lives up to my initial expectations, exceeding them in some areas.
