First Impressions of American Built Arms Company M-LOK Combo Pack Polymer Picatinny Rails
The world of tactical customization can be a daunting one, filled with endless options for rails, grips, and accessories. As a seasoned outdoor and tactical gear specialist, I’ve seen my fair share of attachment solutions, but the American Built Arms Company (AB Arms) M-LOK Combo Pack Polymer Picatinny Rails immediately caught my eye for its promise of lightweight versatility and affordability. Could these polymer rails truly deliver the performance and durability needed for serious use, or were they simply a budget-friendly compromise?
I needed a lightweight, adaptable rail solution for a new AR-15 build I was working on, prioritizing modularity without adding unnecessary weight. Traditional aluminum rails, while robust, often contribute significantly to the overall weight of the firearm. The promise of fiber-reinforced polymer offered a potential solution, hence my interest in the AB Arms offering.
Upon unboxing, the first thing I noticed was the incredibly light weight of the rails. The polymer material felt surprisingly rigid, and the included M-LOK hardware appeared well-made. Compared to aluminum rails I’ve used from Magpul and Midwest Industries, these felt noticeably less substantial but possessed a certain reassuring resilience. I picked the American Built Arms Company M-LOK Combo Pack Polymer Picatinny Rails specifically because it offered a variety of rail lengths (4, 5, and 7 slots) allowing me to configure my accessories exactly how I wanted.
My initial impression was cautiously optimistic. The light weight and modularity were appealing, but I reserved judgment until I could subject them to rigorous testing. Would these polymer rails hold up under the stresses of recoil and hard use, or would they prove to be a weak link in my build? Only time, and plenty of rounds downrange, would tell.
Real-World Testing: Putting American Built Arms Company M-LOK Combo Pack Polymer Picatinny Rails to the Test
First Use Experience
I first tested the American Built Arms Company M-LOK Combo Pack Polymer Picatinny Rails at an outdoor shooting range on a sunny, moderately warm day. I mounted the 7-slot rail to the forend of my AR-15 and attached a weapon light and a forward grip. The installation was straightforward using the provided M-LOK hardware.
The first few magazines were uneventful, the rails held securely, and the accessories remained firmly in place. However, after about 100 rounds, I began to notice a slight softening of the polymer around the mounting points closest to the barrel. While the rails didn’t come loose, it was a bit concerning.
Extended Use & Reliability
After several weeks of consistent use, I continued to monitor the American Built Arms Company M-LOK Combo Pack Polymer Picatinny Rails closely. The initial softening near the barrel hasn’t worsened significantly. However, I did notice some minor scratches and scuff marks on the polymer surface from contact with other gear.
The rails have remained securely attached, even after several hundred rounds of .223 and some moderately rough handling. Cleaning is simple, requiring only a wipe down with a damp cloth. Overall, the American Built Arms Company M-LOK Combo Pack Polymer Picatinny Rails has shown surprising durability for its light weight and material. Compared to my experience with aluminum rails, these polymer rails are more susceptible to cosmetic damage, but they have proven to be functionally reliable.
