Frequently Asked Questions
Are all lower parts kits compatible with every AR-15?
Do all lower parts kits come with a trigger?
No, not all lower parts kits come with a trigger. You can find lower parts kits that include only the basic components, such as springs, detents, pins, and similar items, while more expansive kits will include the trigger and, oftentimes, a pistol grip. Be sure to check out detailed product descriptions to see what is included with each kit.
