First Thoughts on the FAB Defense GL-Core S CP Buttstock with Adjustable Cheekrest Matte Black Synthetic for AR15/M4
For years, I’ve been searching for the optimal balance between compact maneuverability and stable shooting platforms for my AR builds. The market is flooded with buttstocks, but finding one that doesn’t sacrifice comfort for size, or adjustability for weight, has been a persistent challenge. When I stumbled upon the FAB Defense GL-Core S CP Buttstock with Adjustable Cheekrest Matte Black Synthetic for AR15/M4, I was immediately intrigued. The claims of being designed for Israeli Counter-Terrorism units, promising CQB compactness without sacrificing mid-range stability, definitely piqued my interest.
My primary AR is my go-to for home defense and occasional 3-gun competitions. I needed a stock that allowed me to move quickly in tight spaces, like hallways, but still provided a solid cheek weld for accurate shots out to a couple hundred yards.
Unboxing the FAB Defense stock, the first thing I noticed was the weight. It’s surprisingly light, even with the adjustable cheekrest. The matte black polymer feels robust and well-made. Compared to my Magpul CTR, the GL-Core S CP looked noticeably shorter, but with a more substantial cheekrest. I also considered the BCM Gunfighter Stock Mod 0 and the LMT SOPMOD, but the FAB Defense offered a more compelling combination of adjustability and compact size for the price. My initial impression was positive – it felt like a serious piece of kit. I was excited to see how it would perform on the range.
Real-World Testing: Putting FAB Defense GL-Core S CP Buttstock with Adjustable Cheekrest Matte Black Synthetic for AR15/M4 to the Test
First Use Experience
I took the AR equipped with the FAB Defense GL-Core S CP to my local shooting range, which offers both indoor and outdoor lanes. I wanted to test its maneuverability in close quarters and its stability at longer distances. The weather was typical for early spring: damp and a bit chilly. Right away, I appreciated the shorter length of the stock compared to my previous setup when navigating the tighter indoor bays.
It was easy to adjust the cheekrest to my preferred height, and the textured surface provided a secure, comfortable point of contact. The only minor issue was that the adjustment lever felt a bit stiff at first.
Extended Use & Reliability
After several range trips and a few hundred rounds downrange, the FAB Defense GL-Core S CP has held up remarkably well. There are no visible signs of wear or tear on the polymer, even after being bumped around in my range bag. Cleaning is simple; a quick wipe down with a damp cloth removes any dirt or grime. Compared to some cheaper stocks I’ve used in the past, this one feels significantly more durable and well-built.
It has definitely outperformed my expectations, offering a noticeable improvement in both maneuverability and shooting stability. The adjustable cheekrest has made a big difference in my consistency at longer ranges, allowing for a more natural and repeatable cheek weld.

The stock’s shorter length enhances maneuverability in close quarters, making it ideal for CQB scenarios.
