Lighter is better, right? Damn right it is! Nobody wants to carry around more weight than they have to. Ask any good shooter, they'll tell you, "Sure, you might be able to carry a bunch of weight, but why do it if you don't have to?"
So, James Madison Tactical took one of the lightest AR receivers -- polymer -- and made it even lighter by fabricating the first carbon fiber/polymer hybrid 80% lower. It's super lightweight, yet stronger and more durable than other AR-type polymer 80% lowers. It comes with its own jig too, so all you need is a drill press! The finished receiver will shave those precious ounces off the weight of your workhorse too, so you can have a little more comfort during a long day of shooting.
Carbon 50 Polymer 80% Lower Features:
- Weighs just 4.4 ounces when finished
- 20% weight reduction over standard AR lowers
- Stiffer and stronger than many other polymer lowers
- Mil-spec dimensions make the Carbon 50 fit with all other types of mil-spec parts
Why a Polymer AR-15 80% Lower?
Polymer 80% lowers have been well-tested and proven among the AR-15 and 80% lower community. These ultralight lowers afford the same ruggedness as any aluminum lower, yet its construction also affords many unique benefits.
If you’re nervous about machining an 80% lower, this polymer lower will be the perfect way to ease into the practice. Polymer is incredibly simple to drill and mill, and the material is forgiving.
