AR-15 Lower Parts Kit

The AR-15 lower parts kit is a vital piece of an AR-15 that includes the trigger, hammer, bolt catch, trigger guard, magazine catch, magazine catch button, takedown pin, takedown detent spring, and several more components. If you are looking to build an AR-15 you will need the lower parts kit in order to finish your 80% lower receiver. Many AR-15 operators choose to upgrade their lower parts kit to help provide a smoother trigger pull and a tighter shot group. The last thing you want at the range or in a defensive situation is for your lower parts kit to fail and cause your AR-15 to not fire or release the magazine.

All lower parts kits we sell are classified as Mil-spec. This means that you don’t have to buy a specific brand based on the brand of your AR. Stop settling for limited, over-priced selections – get the parts you want at a price you can afford.

Here at the AR-15 Lower Parts Kit Co. we guarantee every product we sell. We only sell American made AR-15 lower parts kits, 80% lowers, and other AR-15 parts. If a product fails because of a manufacturer defect, we’ll replace it for free.

Choose veteran owned AR-15LowerPartsKit.com and have peace of mind when looking for quality, American-made AR-15 parts.
