Step-by-Step Guide to Installing Your AR-15 Complete Lower Parts Kit

Assembly of the lower receiver is straightforward but requires attention to detail. Follow these steps for a successful build:

1. Prepare Your Workspace and Tools

Ensure a clean, well-lit space, along with essential tools such as punches, screwdrivers, and possibly a torque wrench.

2. Install the Trigger and Hammer Group

Insert the trigger into the lower receiver, secure it with trigger pins, then install the hammer and associated Springs, ensuring correct alignment for proper operation.

3. Assemble the Safety Selector and Bolt Catch

Insert the safety selector into its slot, ensuring smooth engagement. Attach the bolt catch and ensure that it moves freely and locks properly.

4. Attach the Pistol Grip and Rear Assembly

Secure the pistol grip with the provided screw or screw assembly. Install the buffer tube, buffer spring, and buffer spacer, tightening to manufacturer specifications.

5. Install the Magazine Catch and Release

Insert the magazine catch and spring into their designated holes, testing for smooth magazine insertion and removal.
