WHAT IS AN AR-15 LOWER PARTS KIT?

Don’t forget to grab an AR-15 lower parts kit to finish your AR-15 80% lower build!

Lower parts kits are composed of essential parts in the lower receiver of an AR-15 that allow it to function as a firearm. These kits will typically include an A2 style pistol grip, a pin kit, various catches, fire control group, trigger guard, buffer retainer kit, and a fire selector. 

The AR-15 lower parts kit is going to be compatible with AR builds chambered in .223 Remington, 5.56 NATO, .300 BLK, and other popular cartridges used in the AR-15 platform.

We offer mil-spec lower parts kits,  and other parts to help enhance the experience with your AR-15 build, such as the Ambidextrous Safety Selector Kit.
