AR Platform Complete Lower Parts Kits and Essential replacement Parts
AR-15 lower parts kits are essential for assembling or upgrading the lower receiver of your AR-15 rifle. These kits include a range of components that ensure proper functionality and reliability for your firearm. With a variety of options available, you can customize your lower receiver to suit your shooting preferences.
The heart of the lower parts kit is the trigger assembly, which consists of the trigger, hammer, and disconnector. These components work together to provide a smooth and consistent trigger pull, enhancing accuracy and control. The fire control group is an integral part of this assembly.
The pistol grip provides a comfortable and ergonomic hold, while the magazine catch and bolt catch allow for easy magazine changes and bolt manipulation. Safety selectors ensure safe operation, and the buffer tube, buffer spring, and buffer provide recoil management and control.
Takedown pins and pivot pins secure the upper and lower receivers together, while the trigger guard offers added protection and accessibility. Other components like the magazine release button, selector detent, and springs ensure proper functioning and reliability.
These lower parts kits offer a comprehensive package of high-quality components that are compatible with most AR-15 lower receivers. Whether you're building a new rifle or upgrading an existing one, these kits provide the necessary parts for a reliable and customized lower receiver.
Also, choose from a wide range of options to personalize your AR-15 lower receiver, from different trigger styles and grip designs to enhanced springs and pins. With attention to detail and precision manufacturing, these lower parts kits are designed to meet the demands of both professional shooters and firearm enthusiasts alike.
