Magpul® MOE® Carbine Stock
The Magpul® MOE® Mil-Spec Carbine Stock is light, comfortable, and tough. Its adjustment latch is shielded from being accidentally moved or snagged.
Magpul® MOE® AR15/M4 Grip
Let’s face it: The AR’s OEM grip just isn’t that comfortable. Magpul® fixed the issue with their MOE® AR15/M4 Grip. It has a noticeably steeper grip angle. No more contorting your wrist to get that high grip purchase.
Magpul® also make the grip thicker than the mil-spec grip, for better comfort. And they’ve turned the inside into a compartment to store gun oil or batteries.
Magpul® MOE® Enhanced Trigger Guard
The Magpul® MOE® Enhanced AR15/M4 Polymer Trigger Guard is way better. It’s ergonomic and gives your trigger finger much more room which is great if you’re wearing gloves.
