Desert tech Quattro lower receiver. Will it work with .50 Beowulf??

Описание: Trying out the Desert tech Quattro AR15 lower receiver. This receiver uses special 4 stack 53 round magazine. These magazines are meant for 5.56/.223 but will it work with the monster round, .50 Beowulf??
In this segment, the presenter is testing whether the *50 Beowulf* rounds will function in their setup with the *REAP Weaponry Bullpup Chassis* and **Palmetto State Armory Jackal upper**. Here's a breakdown of the key points:

Key Points:

1. **Initial Test with 50 Beowulf**:
The presenter begins by loading the *50 Beowulf* rounds into the setup, but initially runs into issues. The rounds don't feed correctly, and the setup jams.
The issue is traced to the use of a *standard AR-15 upper receiver* without the proper *enlarged ejection port* required for larger rounds like the 50 Beowulf.
The jam happens because the round gets stuck during cycling, likely due to the smaller ejection port not being able to accommodate the larger casing.

2. **Fixing the Issue**:
The presenter realizes their *rookie mistake* and acknowledges that the *enlarged ejection port* is necessary for the 50 Beowulf rounds to cycle correctly.
After installing the **larger ejection port**, the setup is able to cycle the rounds correctly.

3. **Magazine Limitation**:
The presenter notes that *50 Beowulf magazines* can only hold **two rounds at a time**, which limits the capacity but is still functional for shooting with multiple loaded magazines.
They mention that you'll need to have a *bunch of magazines* to keep loading them with two rounds each, as the setup won't accept more than that.

4. **Conclusion**:
With the *correct ejection port* in place, the 50 Beowulf rounds cycle properly, and the setup is now functional.
Despite the limited magazine capacity, the presenter still considers the ability to shoot 50 Beowulf with the chassis pretty cool and thanks the viewers for watching.

Final Thoughts:
The *50 Beowulf* test is a success once the proper modifications (larger ejection port) are made. The presenter highlights a *rookie mistake* in not initially realizing the need for an enlarged ejection port but is pleased with the result once the issue is fixed.
The limitation of only being able to load *two rounds per magazine* is a downside but doesn't overshadow the cool factor of being able to shoot 50 Beowulf from the chassis.
