Fightlite MCR Dual Feed Upper 5.56mm 16.25″ Review

First Thoughts on the Fightlite MCR Dual Feed Upper 5.56mm 16.25″

The Fightlite MCR Dual Feed Upper 5.56mm 16.25″ is not just another AR-15 upper receiver. It’s a significant upgrade, transforming your existing AR-15 lower into a belt-fed, magazine-fed hybrid weapon system. This upper boasts the ability to accept both standard AR-15 magazines and M27 linked ammunition, offering unparalleled versatility and firepower.

I’ve always been drawn to the concept of a lightweight, adaptable squad automatic weapon, and the Fightlite MCR seemed to deliver on that promise. The need for a rifle capable of sustained fire during training exercises and potential SHTF scenarios drove me to explore belt-fed options without the weight and expense of a full-fledged machine gun. The dual-feed capability was the key selling point.

My initial impression upon unboxing was one of robust quality. The Fightlite MCR felt solid and well-machined, with a reassuring heft that suggests durability. The manganese phosphate and hardcoat anodized finish gave it a professional and rugged aesthetic.

Compared to a standard AR-15 upper or even other piston-driven uppers I’ve used, the Fightlite MCR is significantly more complex. I considered purchasing a dedicated belt-fed AR-15, but the ability to use standard magazines when belt-fed wasn’t needed was a deciding factor. It also edged out some other quick-change barrel uppers due to its dual-feed functionality.

I was excited but also a bit intimidated. This wasn’t just another drop-in part; this was a complete system. I was eager to see if the Fightlite MCR lived up to the hype and delivered on its promise of reliable dual-feed operation.

Real-World Testing: Putting Fightlite MCR Dual Feed Upper 5.56mm 16.25″ to the Test

First Use Experience

My first experience with the Fightlite MCR Dual Feed Upper 5.56mm 16.25″ was at a private shooting range designed for tactical training. I put it through its paces using both magazine-fed and belt-fed configurations. The range offered a mix of close-quarters and longer-distance targets.

The Fightlite MCR performed well in both dry and slightly dusty conditions. Switching between magazine and belt-fed modes required some familiarization, but the process became relatively smooth after a few practice runs. The weight increase was noticeable, but manageable.

Initially, I experienced a few failures to feed with the belt-fed system. After consulting the operator’s manual and adjusting the gas regulator, the feeding issues resolved, and the rifle ran reliably. The short-stroke gas piston operation kept the rifle cleaner than direct impingement systems.

Extended Use & Reliability

After several months of use, the Fightlite MCR Dual Feed Upper 5.56mm 16.25″ has proven to be a dependable platform. I’ve used it in a variety of training scenarios. These ranged from rapid-fire drills to simulated squad support roles.

Durability has been excellent. The finish has held up well, with only minor signs of wear on high-contact areas. Cleaning the gas piston system is more involved than a standard AR-15, but the improved reliability and cleaner operation are worth the extra effort.

Compared to my standard AR-15 upper, the Fightlite MCR offers a significant increase in firepower and sustained fire capability. It certainly outperforms it in that aspect. However, it is heavier and requires more meticulous maintenance.
