Springfield RISER Mount 1/3 CO-WIT Review

First Thoughts on the Springfield RISER Mount 1/3 CO-WIT

The Springfield RISER Mount 1/3 CO-WIT is designed to elevate your red dot optic, allowing for a more comfortable and efficient shooting experience. Specifically, it enables a 1/3 co-witness with standard AR-15 iron sights. This means that the iron sights appear in the lower third of the optic’s view, providing a backup sighting system without obstructing the primary red dot. The Springfield Armory lineage suggests a certain level of quality and compatibility, making it an intriguing option for AR platform enthusiasts looking to optimize their optic setup.

I was experiencing issues with consistently achieving a comfortable cheek weld while using my red dot on my AR-15. My goal was to find a simple and effective solution for raising the optic to a more natural height, improving both speed and accuracy. The promise of a 1/3 co-witness appealed to me because I wanted to retain my iron sights as a reliable backup without sacrificing the benefits of the red dot.

Unboxing the Springfield RISER Mount 1/3 CO-WIT, I was immediately struck by its simple, no-nonsense design. The matte black finish looked durable, and the mount felt solid in hand, exhibiting no noticeable flex or play. It felt lightweight, which is crucial when adding accessories to an already weighty AR-15 platform.

Compared to some more elaborate and expensive riser mounts I’ve seen, the Springfield RISER Mount 1/3 CO-WIT stands out due to its simplicity and affordability. I considered a few QD (quick detach) options, but ultimately prioritized a secure and streamlined attachment over rapid removal. I also looked at some generic risers on Amazon, but I felt more confident with the Springfield Armory name and reputation for quality.

My initial impression was one of cautious optimism. The simplicity of the design and the Springfield Armory branding instilled confidence, but I was eager to see how it performed in the field. If it delivered on its promise of a solid 1/3 co-witness and improved shooting ergonomics, it would be a worthwhile addition to my AR-15.

Real-World Testing: Putting Springfield RISER Mount 1/3 CO-WIT to the Test

First Use Experience

I first tested the Springfield RISER Mount 1/3 CO-WIT at my local outdoor shooting range, primarily focusing on target acquisition and transitions between close and mid-range targets. The weather was clear and dry, providing ideal conditions for evaluating the optic setup. I ran several drills involving rapid target engagement at 25-50 yards, simulating scenarios one might encounter in tactical training or home defense.

The riser immediately improved my shooting posture and eye alignment with the red dot. Target acquisition felt much faster and more natural compared to my previous setup. The 1/3 co-witness worked perfectly, allowing me to quickly transition to iron sights if needed, without any awkward adjustments.

One minor issue I noticed initially was the slight increase in overall height, requiring a minor adjustment to my cheek weld on the stock. However, after a few magazines, I adapted to the new height and found it significantly more comfortable than before. There were no malfunctions or issues with the mount loosening during firing.

Extended Use & Reliability

After several months of regular use, the Springfield RISER Mount 1/3 CO-WIT has proven to be a reliable and durable addition to my AR-15. It has held zero consistently, even after repeated removal and reinstallation. I’ve used it in various weather conditions, including a few damp range days, and have noticed no signs of rust or corrosion.

The matte black finish has held up well to normal wear and tear, with only minor cosmetic scratches. Cleaning is straightforward; a quick wipe down with a CLP-soaked rag is all that’s needed to keep it in good condition. The mount continues to provide a solid and stable platform for my red dot optic.

Compared to a previous, cheaper riser mount I used, the Springfield RISER Mount 1/3 CO-WIT is a significant improvement. The previous mount was prone to loosening and shifting, causing zeroing issues and frustration. The Springfield mount provides a far more stable and reliable platform, boosting my confidence in my rifle’s accuracy and performance.

Breaking Down the Features of Springfield RISER Mount 1/3 CO-WIT

Specifications

The Springfield RISER Mount 1/3 CO-WIT (SPG GE5077MIN13RM) is a red dot optic mount designed to raise the optic to achieve a 1/3 co-witness with standard AR-15 iron sights. It features a matte black finish for durability and a low-profile aesthetic. It is categorized as a riser mount, intended to elevate the optic for improved ergonomics and sight alignment.

• Riser Mount Style: Specifically designed as a riser mount, this elevates the optic for a more natural cheek weld. This is particularly important for shooters using red dots with AR-15 platforms, improving target acquisition speed.
