5.7x28mm & the Lightweight Rattlesnake Tactical AR57

The 5.7x28mm cartridge has been a topic of interest among shooting enthusiasts for its unique characteristics and performance capabilities.

Developed in the late 1980s, this cartridge offers a high velocity, low recoil experience, making it ideal for both tactical and sporting applications.

In this blog, we dive into the world of 5.7x28mm through the lens of the Rattlesnake Tactical 5.7x28mm complete rifle and the versatile option of building your own AR57 rifle using a complete upper receiver kits.

 

Benefits of  5.7x28mm Ammo

The 5.7x28mm cartridge is renowned for its ability to deliver a high-velocity round that is lighter than traditional cartridges like the 9mm.

This results in reduced recoil, allowing for rapid follow-up shots with high accuracy.

Its performance is comparable to a rifle's, with the added advantage of being used in smaller, more compact firearms.

The cartridge's design facilitates penetration of body armor in combat scenarios, which initially led to its adoption by military and law enforcement agencies.

Building Your Own AR57 Rifle

For those who enjoy custom builds, the option to purchase just the complete upper receiver for the AR57 offers flexibility and personalization.

The upper receiver comes as a complete kit, including the bolt, a 50-round magazine, and a specific 5.7x28mm buffer, ensuring compatibility and functionality.

This setup allows enthusiasts to use their existing AR-15 lower receiver, transforming it into a high-capacity, low-recoil rifle that leverages the unique advantages of the 5.7x28mm cartridge.

The complete upper receiver kit for building an AR57 is designed for ease of installation. It's a plug-and-play solution for those who already possess an AR-15 and wish to explore the capabilities of the 5.7x28mm cartridge without the need to invest in a new rifle.

The inclusion of the 50-round magazine as part of the kit highlights the emphasis on providing a comprehensive solution that meets the needs of shooters looking for both capacity and performance.

The AR57 upper kit is available in either an AR57 16-inch barrel kit for rifle builds, or as an AR57 12-inch barrel kit for that ultra-lightweight SBR (Short Barrel Rifle) or pistol build.

One feature I love about the AR57 upper selection is that the receiver and the handguard are milled out of one piece of aluminum and feature plenty of mounting points for sights, optics, and accessories.

One can easily add optics and sights and be ready to hit the range quickly with the AR57 kit.

The Complete Rattlesnake Tactical 5.7x28mm Rifle

The Rattlesnake Tactical 5.7x28mm rifle is a fully assembled platform that is ready for action right out of the box and only requires sights and/or optic be installed.

It comes equipped with a 50-round magazine, making it an excellent choice for enthusiasts looking for extended shooting sessions without frequent reloads.

The rifle's design incorporates a 16-inch barrel that optimizes the 5.7x28mm cartridge’s velocity, enhancing its range and accuracy over other pistols chambered in the same round.

The lightweight AR57 upper pairs exceptionally well with the lightweight Rattlesnake Tactical RT15 lower receiver for the ultimate highly functional but lightweight and low-recoiling rifle.

If I had to carry a rifle around in the woods all day or be saddled with perimeter duty again on a hot summer day in Georgia, I'd want this rifle for its functionality and low weight!
