6 Benefits of putting a 50 BMG Upper Receiver on a AR-15 Lower Receiver

1.  Cost Savings: Building a 50 BMG rifle from scratch can be very expensive, but using an AR-15 lower receiver can save money compared to purchasing a complete rifle.

2.  Customizability: By using an AR-15 lower, you can choose the grip and stock options to customize your firearm to your liking.

3.  Familiarity: Many gun owners are already familiar with the AR-15 platform, so using an AR-15 lower for a 50 BMG upper receiver can allow them to use a familiar platform for a different caliber.

4.  Accuracy:  Big Kahuna Guns starts with a Lothar Walther Barrel, precision machined for accuracy. 

5.  Protection & Self Defense:  The 50 BMG cartridge can penetrate armor and barriers, stop a vehicle, and defend against heavily armored targets.

6. Long Range & Hunting: The 50 BMG can take down large animals with ease. It is a popular round for hunting big game like elk, moose, and bear. In some states, the 18.5” and 22” barrel uppers are popular with local hog hunters.
