First Impressions of Monstrum Guardian 3-9x32mm AO Rifle Scope
The Monstrum Guardian 3-9x32mm AO Rifle Scope enters the market as a budget-friendly option promising versatility for hunting, target shooting, and tactical applications. Monstrum touts it as a full-featured scope equipped with an adjustable objective (AO) lens, illuminated reticle, and durable construction, all while maintaining a lightweight profile. It’s designed for those seeking an affordable optic without sacrificing essential features.
My interest in this scope stemmed from a need for a temporary solution. I needed a scope to bridge the gap while saving for a higher-end optic. I was also looking for a versatile option that could pull double duty on both my AR-15 and M1A rifles.
Unboxing the Monstrum Guardian 3-9x32mm AO Rifle Scope, my initial impression was of a surprisingly solid build for the price point. The anodized aluminum felt robust, and the adjustments seemed tactile. The scope’s weight of 15 ounces felt balanced in hand.
Compared to a similarly priced CVLife 3-9×40 scope and a slightly more expensive Bushnell Banner 3-9×40, the Monstrum appeared to offer a more streamlined design and the added benefit of an adjustable objective lens. I ultimately chose the Monstrum Guardian 3-9x32mm AO Rifle Scope for its adjustable objective and the promise of parallax correction, hoping for enhanced clarity at varying distances. While not expecting the optical clarity of a Vortex or Leupold, I hoped it would be a functional and reliable placeholder.
Initially, I was cautiously optimistic. It wasn’t going to replace my high end scopes, but it seemed capable of meeting my immediate needs. It presented itself as a functional piece of equipment that could perform adequately.
Real-World Testing: Putting Monstrum Guardian 3-9x32mm AO Rifle Scope to the Test
First Use Experience
My first outing with the Monstrum Guardian 3-9x32mm AO Rifle Scope was at my local shooting range. I mounted it on my AR-15, zeroing it at 100 yards. The weather was clear and sunny.
The initial zeroing process was straightforward, with the 1/4 MOA clicks providing reasonably precise adjustments. I was able to get the AR15 zeroed in within 10 shots. The AO lens noticeably improved target clarity at different distances, especially beyond 100 yards.
The only issue I encountered was the illumination. The red reticle tended to bloom at higher brightness settings, making it less precise in bright daylight. In low light conditions, it was a benefit for acquiring targets quicker.
Extended Use & Reliability
After several months of regular use, the Monstrum Guardian 3-9x32mm AO Rifle Scope has held up reasonably well. There are some minor scratches on the finish from regular handling, but the scope has maintained its zero through multiple range sessions. I have yet to test this scope in heavy rain, though I have been in light rain and it performed admirably.
The turrets, while functional, have become slightly looser over time, losing some of their initial tactile feedback. Cleaning the lenses is simple enough, but I’ve noticed they seem to attract dust more easily than my higher-end scopes. Compared to my experiences with Vortex scopes, the Monstrum lacks the same level of robustness and refined adjustments.
Overall, for the price, it has exceeded my expectations. It’s performed its intended function well as a temporary optic while I save for a better piece of glass. It will also serve it’s function as a short/medium range scope on my AR15.
Breaking Down the Features of Monstrum Guardian 3-9x32mm AO Rifle Scope
Specifications
The Monstrum Guardian 3-9x32mm AO Rifle Scope boasts several key specifications that contribute to its functionality. It features a 3-9x magnification range, useful for engagements from close quarters to medium distances. Its 32mm objective lens allows for decent light transmission, though not exceptional in very low-light conditions.
The scope uses a Second Focal Plane (SFP) reticle, meaning the reticle size remains constant regardless of magnification. It also features a red-illuminated MOA reticle, powered by a CR2032 battery. The scope weighs 15 ounces, is 12 inches long, and has a 1-inch tube diameter, requiring compatible mounting rings.
These specifications dictate the scope’s intended use. The adjustable objective lens is key, allowing for parallax adjustment and sharper image focus. The MOA adjustments are standard, offering familiar and precise control for most shooters.
Performance & Functionality
The Monstrum Guardian 3-9x32mm AO Rifle Scope performs its core function adequately. The 3-9x magnification is versatile enough for a variety of shooting scenarios. Accuracy is acceptable, with the scope holding zero reasonably well.
However, there are some weaknesses. The optical clarity is not on par with higher-end scopes, particularly at higher magnifications. The illumination, while functional, can be overly bright at the higher settings.
The scope meets expectations for its price point, but it doesn’t exceed them. It’s a decent performer, but not exceptional.
Design & Ergonomics
The Monstrum Guardian 3-9x32mm AO Rifle Scope features a straightforward design. The anodized aluminum construction feels durable enough. The included throw lever on the magnification ring is a nice touch, allowing for quick and easy magnification adjustments.
The scope is generally user-friendly. The adjustable objective is easy to manipulate. The turrets, however, could benefit from more tactile clicks.
Durability & Maintenance
Given its construction, the Monstrum Guardian 3-9x32mm AO Rifle Scope should last a reasonable amount of time with proper care. The 6061 aircraft-grade aluminum construction suggests decent durability. The nitrogen-charged tube provides fog and water resistance.
Maintenance is simple. Cleaning the lenses with a microfiber cloth is all that’s typically required. The 1 year warranty provides some peace of mind.
Accessories and Customization Options
The Monstrum Guardian 3-9x32mm AO Rifle Scope doesn’t come with a plethora of accessories, focusing on the core functionality of the optic itself. The integrated throw lever is a notable inclusion, aiding in quick magnification adjustments. Aftermarket options are constrained by the one-inch tube diameter, but plenty of one-inch scope rings and mounts are readily available.
The scope is compatible with most standard Picatinny rail mounting systems, increasing its adaptability across various rifle platforms. While Monstrum doesn’t offer proprietary add-ons for this specific model, standard accessories like scope covers and lens cleaning kits can be easily integrated.
