The MK4 is a precision oriented upper receiver. Accuracy and consistency is the main focus here. No frills, just the most precision you can squeeze out of 5.56 AR platform without the price tag. I guarantee Sub MOA 5-shot groups with high quality ammo. In my personal testing I have gotten right at 1 MOA 10-shot groups. These are gassed to perform well with or without a suppressor. If you plan on using a lot of steel cased ammo we recommend Carbine Buffers and Springs.
