VISM Pro Series Top Mounted Deployable Front and Rear Sight Review

Let’s Talk About VISM Pro Series Top Mounted Deployable Front and Rear Sight

Back-up iron sights (BUIS) are crucial for any serious AR platform rifle, offering a reliable aiming solution should your primary optic fail. The VISM Pro Series Top Mounted Deployable Front and Rear Sight aims to provide a cost-effective solution for those seeking dependable BUIS without breaking the bank. I’ve spent over a decade evaluating tactical gear, and backup sights are a must-have for any serious shooter.

My primary goal in searching for a new set of BUIS was to find a durable, low-profile option that wouldn’t interfere with my existing optic setup. I wanted something I could trust in a pinch, without adding unnecessary bulk or weight to my AR. The VISM Pro Series Top Mounted Deployable Front and Rear Sight seemed to check those boxes.

Upon unboxing, I was initially impressed with the sight’s sleek, low-profile design. The aluminum body felt solid, and the spring-loaded deployment mechanism had a satisfying snap. The A2-style front sight post and dual-aperture rear sight appeared well-made, though I immediately noticed a slight wobble in the front post—a concern echoed in some user reviews.

I considered other options like Magpul’s MBUS sights, known for their polymer construction and reliability. However, the VISM sights offered a more compact profile when folded down, and the aluminum construction appealed to my preference for durability, at least in theory. Ultimately, the price point combined with the promise of a robust, low-profile design led me to choose the VISM Pro Series Top Mounted Deployable Front and Rear Sight.

My first impression was cautiously optimistic. The sights looked the part and felt reasonably solid, but the front sight wobble raised a red flag that I’d need to address before truly trusting them. I hoped that a simple fix, like the Teflon tape method suggested by another user, would resolve the issue and allow these sights to perform as intended.

Real-World Testing: Putting VISM Pro Series Top Mounted Deployable Front and Rear Sight to the Test

First Use Experience

I first tested the VISM Pro Series Top Mounted Deployable Front and Rear Sight at my local outdoor range. It was a sunny day with a slight breeze, providing ideal conditions for sighting in. I mounted the sights on my AR-15, ensuring they were securely attached to the Picatinny rail.

The initial deployment was smooth and quick with the push-button mechanism. I immediately noticed, as others have, the front sight post was loose. After attempting to zero the rifle at 25 meters, I found it incredibly difficult to get it on target. The front sight post needed to be adjusted so far down that it was almost completely recessed into the housing.

After my initial experience, I was already second-guessing the purchase.

Extended Use & Reliability

After several range sessions and field exercises, my concerns about the VISM Pro Series Top Mounted Deployable Front and Rear Sight have only intensified. The initial wobble in the front sight post persisted, even after applying Teflon tape. I had to reapply the tape every range visit.

The finish has held up relatively well, with only minor signs of wear and tear. However, the overall reliability of the sights is questionable. I found the rear sight on my LR-308 build repeatedly folded down under recoil, completely obstructing my view.

Compared to my previous experiences with other BUIS from Magpul and Troy Industries, the VISM Pro Series sights simply don’t measure up. The unreliability is a critical flaw for backup sights. Durability and reliability are key when considering such a sight, especially on an AR platform.

Breaking Down the Features of VISM Pro Series Top Mounted Deployable Front and Rear Sight

Specifications

• The VISM Pro Series Top Mounted Deployable Front and Rear Sight includes both front and rear sights that deploy with a push of a button. This provides rapid deployment when your primary optic fails.
• The front sight features an A2 front sight post that is fully adjustable for elevation. Theoretically, this allows you to zero your rifle at various distances.
• The front sight height is designed for handguard rails, monolithic receivers, and gas blocks that are at the SAME height as the AR receiver Picatinny rail. This ensures proper alignment and compatibility.
• Front Sight Dimensions: 2.4″L X 1.1″W X 0.8″H, Weight: 2.0 oz. The compact size and lightweight design minimize added bulk.
• The rear sight features an A2 dual aperture (large & small) that is fully adjustable for windage. A dual aperture offers versatility for different lighting conditions and target sizes.
• A knurled windage knob makes adjusting the windage an easy task. This allows for quick and precise adjustments in the field.
• The rear sight’s low-profile design folds flat, to fit under the majority of scopes. This prevents interference with your primary optic.
• Rear Sight Dimensions: 2.4″L X 1.2″W X 0.8″H, Weight: 2.3 oz. Like the front sight, the rear sight is lightweight and compact.
• Aluminum main body with steel A2 front post and A2 rear aperture construction provides decent durability and corrosion resistance. The steel components are critical for long-term reliability.
• Mounts onto Picatinny Mil-STD 1913 rails, mounting tool included for ease of installation. Compatibility with standard Picatinny rails is essential.

Performance & Functionality

The VISM Pro Series Top Mounted Deployable Front and Rear Sight suffers from significant performance issues. Accuracy is compromised by the loose front sight post and limited elevation adjustment.

The sights do not consistently hold zero, and the rear sight’s tendency to fold down under recoil makes them unreliable in a self-defense or tactical situation. The design is aesthetically pleasing, but the functional flaws overshadow any positive aspects. They failed to meet even my modest expectations for backup iron sights.

Design & Ergonomics

The aluminum construction and low-profile design of the VISM Pro Series sights are visually appealing. The push-button deployment mechanism is easy to use, but the loose front sight post undermines the overall build quality. The sights are lightweight and compact, minimizing added bulk to the rifle.

However, the ergonomic benefits are negated by the functional issues. The learning curve is minimal. The overall design requires no specialized tool or experience.

Durability & Maintenance

The VISM Pro Series Top Mounted Deployable Front and Rear Sight appears to be made from decent materials, but questionable construction impacts long-term durability. The finish has proven relatively resistant to scratches and wear, but the loose components and unreliable deployment mechanism raise concerns about its longevity.

Maintenance is simple, requiring only occasional cleaning with a brush and solvent. However, the need to frequently reapply Teflon tape to the front sight post is a significant drawback. Overall, the sights’ long-term durability is questionable.

Accessories and Customization Options

The VISM Pro Series Top Mounted Deployable Front and Rear Sight does not offer extensive customization options. The A2-style front sight post can be replaced with aftermarket options, but that won’t fix the actual housing.

While the sights are compatible with standard Picatinny rails, there are no readily available accessories specifically designed for them. The lack of customization options is not a major concern for BUIS, but the limited upgrade potential further detracts from their value.

Who Should Buy VISM Pro Series Top Mounted Deployable Front and Rear Sight?

The VISM Pro Series Top Mounted Deployable Front and Rear Sight might appeal to budget-conscious shooters looking for a low-profile BUIS solution for range use only. It is not suitable for duty use or tactical applications where reliability is paramount.

Those who value reliability and durability in their backup sights should skip this product. Competitive shooters, law enforcement professionals, and anyone who relies on their rifle for self-defense should invest in a higher-quality option.

A thread locker to keep the front sight post from wobbling is a must-have accessory. I would also recommend a different back up sight entirely!

Conclusion on VISM Pro Series Top Mounted Deployable Front and Rear Sight

The VISM Pro Series Top Mounted Deployable Front and Rear Sight promises a budget-friendly solution for backup iron sights, but ultimately falls short in terms of reliability and performance. The loose front sight post, limited adjustment range, and tendency for the rear sight to fold down under recoil make them unsuitable for serious use.

The price point is attractive, but the functional flaws outweigh any potential cost savings. The VISM Pro Series Top Mounted Deployable Front and Rear Sight simply does not offer the reliability and durability required for a dependable backup sighting system.

I cannot recommend the VISM Pro Series Top Mounted Deployable Front and Rear Sight. Invest in a higher-quality option from a reputable manufacturer like Magpul, Troy Industries, or Daniel Defense for true peace of mind. A reliable backup sighting system is not an area where you want to cut corners.
