First Impressions of OpticsPlanet Exclusive Moriarti AR-15 16in 300 Blackout Upper Receiver, Triport
The OpticsPlanet Exclusive Moriarti AR-15 16in 300 Blackout Upper Receiver, Triport immediately piqued my interest as a versatile option for both home defense and short-range hunting. The Moriarti name, while not a household name like some of the bigger AR-15 manufacturers, has been gaining traction for offering affordable components that often punch above their weight class. The allure of a complete upper receiver in the 300 Blackout caliber, known for its subsonic capabilities and effectiveness in close quarters, combined with the OpticsPlanet exclusive “Triport” muzzle brake, sparked my curiosity.
My AR-15 has always been chambered in 5.56 NATO, but I was looking for a setup more suitable for hog hunting in dense brush. I also needed something quieter and more manageable for potential home defense situations. I wanted to expand my AR’s capabilities without breaking the bank.
Upon unboxing, the upper receiver assembly appeared well-packaged. The anodized finish was smooth and consistent, giving it a professional look. The weight felt balanced, suggesting a reasonable build quality. It wasn’t excessively heavy, which is crucial for maneuverability in the field.
I considered other 300 Blackout uppers from companies like Aero Precision and Palmetto State Armory, but the OpticsPlanet Exclusive Moriarti offered a more attractive price point. I also liked the unique design of the Triport muzzle brake and its potential for recoil reduction. Ultimately, the combination of price, features, and the promise of a complete, ready-to-install upper led me to choose this Moriarti offering.
My first impression was one of cautious optimism. While the price raised some concerns about long-term durability, the initial fit and finish suggested a product that could potentially deliver on its promises. I was eager to get it to the range and see how it performed.
Real-World Testing: Putting OpticsPlanet Exclusive Moriarti AR-15 16in 300 Blackout Upper Receiver, Triport to the Test
First Use Experience
I tested the OpticsPlanet Exclusive Moriarti AR-15 16in 300 Blackout Upper Receiver, Triport at my local outdoor shooting range, focusing on accuracy and functionality at 50 and 100 yards. I primarily used both supersonic and subsonic ammunition to evaluate its performance across different loads.
The weather was mild, but a slight crosswind presented a minor challenge. The upper receiver paired seamlessly with my existing AR-15 lower, and the initial cycling of rounds felt smooth. I was initially impressed with the reduced recoil compared to my 5.56 upper, likely due to the 300 Blackout’s inherent characteristics and the Triport muzzle brake. The upper performed admirably, with no immediate failures to feed or eject.
One minor issue I noticed during the first range session was that the muzzle brake seemed to generate more concussion than I anticipated. This directed sound waves back towards the shooter and those nearby.
Extended Use & Reliability
After several weeks of regular use, the OpticsPlanet Exclusive Moriarti AR-15 16in 300 Blackout Upper Receiver, Triport has proven to be a reliable performer. I’ve put several hundred rounds through it, and it has consistently cycled both supersonic and subsonic ammunition without any major issues.
There are some slight signs of wear on the anodized finish around the ejection port, but this is to be expected with normal use. I regularly clean and lubricate the upper receiver after each range session, and it has been relatively easy to maintain. Cleaning is straightforward, as the components are easily accessible.
Compared to my previous experiences with higher-end AR-15 uppers, the Moriarti offering performs surprisingly well, especially considering the price difference. While it might not have the same level of refinement as some of the premium brands, it delivers reliable performance and good accuracy for its intended purpose.
Breaking Down the Features of OpticsPlanet Exclusive Moriarti AR-15 16in 300 Blackout Upper Receiver, Triport
Specifications
The OpticsPlanet Exclusive Moriarti AR-15 16in 300 Blackout Upper Receiver, Triport boasts several key specifications. It features a .300 AAC Blackout chambering, which is ideal for subsonic suppressed shooting and offers greater energy transfer at shorter distances compared to 5.56 NATO. The 16-inch barrel strikes a good balance between maneuverability and ballistic performance.
The barrel features a 1-7 twist rate, which is optimal for stabilizing both lighter supersonic and heavier subsonic bullets. A pistol length gas system is used, which is standard for 300 Blackout AR-15s and ensures reliable cycling. The barrel is threaded 5/8×24, allowing for the attachment of various muzzle devices and suppressors.
It features a 12-inch free-float M-LOK handguard, providing ample space for mounting accessories such as lights, lasers, and grips. The Triport Muzzle Brake is designed to reduce recoil and muzzle rise. The upper receiver is finished with a durable anodized finish in black.
These specifications matter because they directly impact the upper’s performance and usability. The 300 Blackout caliber offers versatility, while the 16-inch barrel provides a good balance between size and velocity. The M-LOK handguard allows for customization, and the Triport muzzle brake enhances control.
Performance & Functionality
The OpticsPlanet Exclusive Moriarti AR-15 16in 300 Blackout Upper Receiver, Triport performs its intended job of reliably cycling 300 Blackout ammunition with decent accuracy. I was able to consistently achieve groupings of around 2 MOA at 100 yards with quality supersonic ammunition. Subsonic ammunition produced slightly wider groupings, but still acceptable for close-quarters applications.
The primary strength is its reliable cycling and manageable recoil. The Triport muzzle brake effectively reduces muzzle rise, allowing for faster follow-up shots. One area that could be improved is the smoothness of the bolt carrier group. It felt slightly gritty compared to some of the higher-end options I’ve used.
Overall, the upper receiver meets my expectations for a budget-friendly 300 Blackout option. It provides reliable performance and acceptable accuracy for its price point.
Design & Ergonomics
The upper receiver features a standard AR-15 design, with a few notable differences. The M-LOK handguard is comfortable to grip and provides plenty of space for accessories. The Moriarti logo is discreetly engraved on the side of the receiver.
The build quality is adequate for the price. The anodized finish appears durable, and the components fit together snugly. There is no noticeable wobble or play between the upper and lower receivers. The only slight concern is the weight of the Triport muzzle brake, which adds some bulk to the front of the rifle.
The upper is user-friendly and requires no special tools or knowledge to install on a standard AR-15 lower. The learning curve is minimal, and anyone familiar with AR-15s should be able to operate it without any issues.
Durability & Maintenance
Based on my experience so far, the OpticsPlanet Exclusive Moriarti AR-15 16in 300 Blackout Upper Receiver, Triport should last for a reasonable amount of time with proper care and maintenance. The anodized finish provides good protection against corrosion, and the components appear to be reasonably well-made.
Maintenance is straightforward, requiring only basic cleaning and lubrication after each use. The upper receiver disassembles easily for cleaning. I anticipate that the barrel will be the component most likely to require replacement over time, depending on usage and ammunition type.
Accessories and Customization Options
The OpticsPlanet Exclusive Moriarti AR-15 16in 300 Blackout Upper Receiver, Triport does not come with any accessories beyond the complete upper receiver assembly itself. However, the M-LOK handguard provides ample opportunities for customization.
The upper is compatible with a wide range of AR-15 accessories, including optics, lights, lasers, grips, and slings. The 5/8×24 barrel threads allow for the use of various muzzle devices and suppressors. The upper is also compatible with most standard AR-15 lower receivers and magazines.
