Palmetto Stat Armory JAKL Upper Receiver with the Desert Tech MDRX Lower Receiver
n this video, we introduce a custom rifle build featuring a Palmetto State Armory Jackal Gen 1 upper receiver and a Desert Tech Quattro lower receiver. They discuss modifications made to ensure compatibility, such as cutting out the QD Mount on the Quattro lower receiver and filing down the bolt catch to allow proper fit with the upper receiver. The Quattro lower features a proprietary magazine that holds more ammunition and ambidextrous controls for faster operation, including a bolt catch/release on both sides.
In this video, the presenter showcases a custom rifle build featuring a *Palmetto State Armory Jackal Gen One upper receiver* and a **Desert Tech Quattro lower receiver**. Here's a breakdown of the key points:
Key Build Details:
The *Jackal Gen One upper receiver* from *Palmetto State Armory* is paired with the **Desert Tech Quattro lower receiver**, which is a unique combination not possible with the **Jackal Gen 2**.
The *JMac Skeleton Folding Stock* is used for the build.
Modifications:
To make the parts fit together, the presenter had to perform a couple of modifications:
1. *QD Mount**: The **Desert Tech Quattro lower receiver* has a *QD mount* that protrudes too far, preventing the *Jackal upper receiver's back plate* from fitting properly. The presenter cut this mount with a *Dremel* (though they later suggest drilling it out might have been a better option). A new *end plate* will be purchased for about $100 to fix this.
2. *Bolt Catch Modification**: The back end of the **bolt catch* had to be filed down to fit properly in the slot of the **Jackal upper receiver**, as it was engaging even with a full magazine, causing the bolt to lock back prematurely. This modification was done carefully to avoid damaging the **expensive upper receiver**.
Features of the Quattro Lower Receiver:
*Proprietary Fat Standard Magazine**: The **Desert Tech Quattro* comes with a **fat standard magazine**, providing more ammunition capacity, making it great for reducing the need for frequent magazine changes.
*Ambidextrous Controls**: The receiver features **ambidextrous magazine releases**, though the presenter notes it's not critical for them but useful for left-handed shooters. More importantly, it has an **ambidextrous bolt catch* and **bolt release**, allowing for faster and more efficient operation, especially when reloading.
Overall Impressions:
The *Jackal Gen One* and *Desert Tech Quattro* combination is described as making a really cool, functional rifle.
The build is exciting, and the presenter plans to take it out for shooting soon, though they haven’t tested it yet at the time of filming.
The rifle is designed to be versatile, with the *ambidextrous controls* adding to its overall efficiency and usability.
Call to Action:
The presenter encourages viewers to check out their content on **Rumble**, where they’ll show more in-depth projects and videos about builds like this.
Closing:
The video wraps up with a thank you to viewers and a reminder to follow them on Rumble for future content.
